How to install TWRP custom recovery (no MCU updates possible afterwards) - MTCB Android Head Units General

pakidermo5000 said:
Ok, I need some help here to understand pretty basic things. I think I am trying to do the wrong thing. I get into bootloader mode. I get the black screen and detection of "class for rockchip" in device manager.
Now, I want to flash TWRP. My idea was to get into bootloader mode and use ADB to flash TWRP. But, I cannot connect to HuiFei when in bootloader mode because adb does not see any device.
Instead, if I boot the unit and use Wifi ADB, then I can connect to the unit.
So, should I flash TWRP through wifi ADB with the unit booted, or should I do it through bootloader mode? I could probably do it via recovery, but I do not really know how (just do update from sd card and select the TWRP I downloaded from 1-2-hak ?) otherwise, how do I do it if my adb does not detect any device?
sorry for the basic questions, but it is the first time I am doing this...

You dont need bootloader to flash TWRP. You just need to know how to get there if something goes wrong.
Check this link http://www.freaktab.com/showthread....itions-from-android-No-PC-needed-For-rockchip
get the flash_image from the link.
the get your wifi adb going
do a
adb push flash_image /sdcard/flash_image
adb push TWRP_KGL-7650G /sdcard/TWRP_KGL-7650G
then i go to adb shell
usually just cp them to dev
cd /sdcard
cp flash_image /dev/flash_image
cp TWRP_KGL-7650G /dev/TWRP_KGL-7650G
then flash it
/dev/flash_image recovery /dev/TWRP_KGL-7650G
then if you want to test
reboot recovery
you will need an mouse attached.
I am gong to see if I can get the touch working in this when I get my unit back.
Do a backup of the whole system in TWRP.
Then you are pretty well set.
Not sure if you need original recovery to update new MCU.images. When i uploaded mine I just flashed back the original recovery in the same way.
You can back up the original recovery by the steps in the link above. Which is good to have a complete copy of what you have now before tinkering too.
Hope that helps.

v3 with init.d support!
Here are v3 images for both screen resolutions in both KGL and KLD variants:
KVV_KitKat_XRESxYRES_yymmdd_rooted_light_reparted_init.d_v3:
rooted:
- ClockworkMod's Superuser apk, su binary and root daemon (root daemon needed on 4.3+ roms)
reparted: (seems popular these days )
- system reduced from 768MB to 512MB
- oem reduced from 128MB to 64MB
- data increased from 1GB to 3GB
- internal sd in now a bit less than 4GB
removed apks:
- Gmail2 (available on Play Store)
- Maps (available on Play Store)
- GoogleSearch (available on Play Store)
- VoiceSearch (included in GoogleSearch on Play Store)
- Talkback (available on Play Store)
- Google TTS and its libs and files (available on Play Store)
- Adobe Reader and its libs (available on Play Store)
- Instructions (surely useless, not relevant and badly translated from chinese...)
- Chinese and Japanese Keyboards (also removed their libs that are now useless)
- Navgear (just a stupid shortcut to the selected nav app in settings...)
updated/added apks:
- Google Play Store (updated to latest version)
- Google Play Services (updated to latest version with libs correctly installed so no more Google Play Services errors! Fixed on 1024x600 v3.1 thanks to @ESTIMULO)
- Browser bookmarks sync adapter (added, missing in KLD and KGL)
- Google calendar sync adapter (added, missing in KGL)
- Google contacts sync adapter (added, missing in KGL)
modded:
- init.d support added (late in boot process so every external storages are mounted), you can drop your scripts to /etc/init.d (chmod 755)
- added compatibility symlinks for storage mount points (it may fix issues with apps using hard-coded path to access sdcards and usb, if not it won't hurt anywway!)
- flash_image binary by Androtab, with dump_image and erase image symlinks to flash/erase/dump full partitions (dump_image return an error at the end but you can ignore it, dump is valid)
IT WILL WIPE YOUR DATA AND INTERNAL SD so backup first!
Please note that 1024x600 versions are untested as I don't own such a device but it's modded the same way so it should work flawlessly.
Updated TWRP image
This is an updated Team Win Recovery Project image based on 2.7.0.0 by Abdul from freaktabs (most credits goes to him! )
Updated fstab to new KK part scheme (was mounting kpanic and oem instead of system and internal sd)
updated kernel, modules and config files (full SElinux support)
Still no touchscreen you have to use a mouse. I've spent days trying to make touchscreen work but no luck, I'm starting to think that touchscreen is handled by mcu which then emulates a touch device or some weird things like that...
Now with a 1024x600 image
Please note that 1024x600 version is untested as I don't own such a device but it's Updated the same way so it should work.

How to flash recoveries back and forth to backup/restore data over flashes
Install Jack Palevich's Terminal Emulator for Android from Play Store and use a root explorer to save the apk file to your sd card or usb storage.
Download flash_image binary and use a root explorer to copy it to /system/bin and change permission to 755 rwxr-xr-x (if you are on one of my modded fw it's already installed you can skip this step).
Launch Terminal Emulator and type su to gain root, then type cd /path/to/recovery/folder, then type flash_image recovery twrp.img
You now have twrp installed, type reboot recovery to reboot to twrp.
In twrp use a mouse and go to backup menu to backup data (do not backup to internal sd it will be formatted by update).
Now reboot to system and place update.img at the root of you external sd or usb storage but don't update if prompted
Launch Terminal Emulator and type su to gain root, then type cd /path/to/recovery/folder, then type flash_image recovery recovery.img
You now have standard recovery installed, type reboot recovery to reboot to recovery.
Now you can flash update.img from the menu using power button.
When back into Android use backed up Jack Palevich's Terminal Emulator for Android apk to reinstall it quickly without having to set up google account.
Launch Terminal Emulator and type su to gain root, then type cd /path/to/recovery/folder, then type flash_image recovery twrp.img
You now have twrp installed, type reboot recovery to reboot to twrp.
In twrp use a mouse and go to restore menu to restore data.

Just a quick update.
I have copied over multiple different SU using TWRP to my stock 1024 x 600 4.4.2 unit. All them result in the same thing. Superuser not being able to use it. I have confirmed its there, messed with permissions on su and the system folders.
On thing I noticed through the TWRP command line is that SELinux is enabled. So thinking I might to research that to figure out if I need to do anything to get around that.
Back to the drawing board.

I've updated the twrp image for 1024x600 with 100% scaling factor so it should fit the whole screen now. Grab it HERE if you want to try.
Why don't you just flash a superuser zip from twrp, it will take care of the files, permissions and starting the daemon for you. You can grab ClockworkMod's superuser installer here: http://download.clockworkmod.com/superuser/superuser.zip

Note:
You can get required files here: https://docs.google.com/file/d/0B3FXCUVt554Mb1Nnai14eWM2cWc/edit
This is not provided by me! I copied the link from @pakidermo5000's old OP-Post
With TWRP MCU-Updates are no longer possible!
Normally you do not need TWRP as any custom roms can and have to be flashed using original recovery

"Twrp image" Link is dead

Guy I know this is bringing up a thread from the dead but a question. I did install TWRP but my issue is when in TWRP to do a backup it is only backing up about 60MB of data even w/ all partitions chosen. It shows 0MB in data, is there a way I can back up the entire ROM like you can do on my android based phones w/ TRWP or CM recovery? Also I've read how to switch to stock recovery but whenn I go to TWRP and backup it just backs up TWRP backup files (ext4.win) no .img file is created. I think I just need a copy of the stock recovery.img and then i'd be golden. Am I wrong? If im not, does anyone know where I can find that?
Thanks
Dave

Must appreciated man, it was perfect. It seems TWRP is pretty much useless on these devices for bare metal backup/recovery like they are on phones.

If you must here is a website where I got it (although not much you can do with it) be sure to have a mouse as the touch screen doesn't work. If you need to revert, which you will if you plan to update you will need to find a copy of the stock recovery.

rollback recovery stock
Hi.
Do you have any idea how to get back to the recovery stock version? I installed the TWRP under Rk3188 Stereo Card, it works fine but at the time of updating the file upgrade.img does not work.
Thanks you for your help.

I have a post on this somewhere. Search for it but here is what I have documented. Here is the joying stock recovery if that'll help you. https://www.dropbox.com/s/h5o46v24911nbsp/Joying stock recovery.img?dl=0 Same process as my post on installing TWRP on these except you use this image.
Dave

Ok, let me get this straight...
1. With TWRP you can't flash mcu.img (but you can flash update.img? how does this exactly work? how do I flash an update.img from TWRP? or do I lose the ability to flash update.img as well?)
2. The ROMs do not come with recovery images and overwrite TWRP? I thought they did, like other ROMs...

DOWNLOAD THE SKIPSOFT UNIFIED ANDROID TOOLKIT *HERE* (FROM SKIPSOFT.NET)
NOTE: As the exe files are not Digitally Signed with a Microsoft Certificate they 'may' get picked up as potentially harmful by Antivirus Programs and deleted on first run. If this happens restore the file and exclude it from future scans to use it. This seems to happen mostly on AVG Free and Norton which is why I switched to BitDefender which is much better.
Credits: ChainsDD for Superuser, Chainfire for SuperSU, koush and the clockworkmod team for cwm and the universal driver pack, 1wayjonny for the adb/fastboot driver pack, Adam Lange for all his support and help with the insecure kernels.
--------------------------------------------------------------
WHAT IS THE DIFFERENCE BETWEEN PUBLIC (FREE) AND PROFESSIONAL (DONATE) VERSIONS?
THE PUBLIC VERSION OF THE TOOLKIT INCLUDES EVERYTHING YOU COULD NEED TO MANIPULATE YOUR DEVICE. NOTHING IS RESTRICTED.
ACTIVATING THE PROFESSIONAL VERSION ADDS THE MOST USEFUL FUNCTION IN THE TOOLKIT, THE ABILITY TO CHECK FOR 'AUTO UPDATES' DIRECTLY VIA THE TOOLKIT AND HAVE THEM PUSHED TO YOUR PC RIGHT AWAY AS SOON AS THEY ARE UPLOADED WITHOUT NEEDING TO DOWNLOAD THE WHOLE TOOLKIT EVERY TIME. YOU WILL ALWAYS HAVE THE LATEST VERSION AS SOON AS IT IS MADE AVAILABLE. THIS MEANS SMALLER UPDATES CAN BE SENT OUT MORE FREQUENTLY, SUCH AS ADDING A SINGLE FUNCTION, FIXING A BUG OR ADDING COMPATIBILITY FOR A SINGLE CARRIER. THE SMALLER UPDATES WILL BE COMPILED AND RELEASED TO THE XDA COMMUNITY AS A FULL (PUBLIC) DOWNLOAD VERSION SO PROFESSIONAL VERSIONS ARE ALWAYS UPDATED SOONER.
THE PRO VERSION ALSO ADDS THE ABILITY TO CHECK FOR THE LATEST VERSION OF SUPERUSER AND RECOVERY FILES AND DOWNLOAD THEM DIRECTLY TO THE TOOLKIT.
THE 'QUICK PICKS' SECTION[/B] ALLOWS YOU TO PROGRAM UPTO 10 SLOTS WITH TASKS THAT YOU MAY PERFORM ON A REGULAR BASIS OR JUST WANT TO KEEP A SET OF TASKS IN 1 PLACE. THEN JUST SELECT THE SLOT AND IT WILL REMEMBER ALL YOUR SETTINGS FOR THAT TASK AND RUN IT.
PRO USERS CAN ALSO SELECT THE "ANY BUILD" OPTION IN THE BUILD SELECTION SCREEN TO ROOT ANY BUILD (USEFUL IF YOUR BUILD IS NOT LISTED).

--------------------------------------------------------------
PLEASE READ THE *HELP* PAGE AT http://www.skipsoft.net/?page_id=1269 IF YOU HAVE ANY QUESTIONS. I HAVE TAKEN A LOT OF TIME TO WRITE IT AND SOMETHING ON THERE SHOULD ANSWER 99% OF PROBLEMS.
--------------------------------------------------------------
1. INSTALLING ADB/FASTBOOT DRIVERS
The first thing you need to do is to install the adb/fastboot drivers. These are needed so that you can unlock your bootloader, root your device and perform other adb/fastboot functions.
THE DRIVERS CAN BE INSTALLED DIRECTLY VIA THE TOOLKIT. OPTION 1 IN THE MAIN MENU.
If drivers are not installed or there is an exclamation mark next to the device:
Plug the device in to a usb cable directly connected to your motherboard.
In the Device Manager a new item, usually called Android 1.0 should pop up in the list.
Right click on the device item then left click on Update Driver Software. Select 'browse my computer' and then 'Let me pick from a list'.
If no adb interface driver appears in the list then untick 'Show compatible hardware' and find the Android or Samsung adb interface driver.
If you cannot find either of these click Have Disk, browse to the Toolkit install folder, drivers folder, click on android_winusb.inf and click Open.
Click OK and select Google ADB Interface.
Make sure you have USB debugging enabled in settings, developer options. In Android 4.2.2 or later you have to enable the developer options screen by going to settings, About on your device and click on Build number at the bottom 7 times until it says You are now a developer. If you have already enabled usb debugging then unplug/replug the usb cable.
On Android 4.2.2 or later when you replug the usb cable after enabling usb debugging for the first time you will get a popup asking you to authenticate your pc. Tick 'Always allow' then click 'ok'.
--------------------------------------------------------------
2. USING SKIPSOFT UNIFIED ANDROID TOOLKIT
When starting the Toolkit you will first be asked which device you want to work with. Working folders will be created and the device files downloaded. You will then be taken to the Model/Build selection screen where you can do a number of things (other than select your model/build): Type '00' to enter your activation code and enable pro features, 'i' will take you to the Information and Help Section, 'a' will give you information on how to add support for a new build.
Supported builds are listed in the Model/Build selection screen and typing the associated number (i.e. 11) will download needed boot and recovery files (stock and custom recovery) then check for and download the latest superuser files available and custom recovery (pro versions only), verify all the files and start the Main Menu. You can now use all the functions and tools the Android Toolkit offers. Pro users can select the "any build" option to root any build (useful if your build is not listed).
--------------------------------------------------------------
USEFUL INFORMATION
Enable Developer options for usb debugging
Go to Settings, System section, About device and tap on 'Build number' 7 times until it says you are now a developer. You can now go to Settings, System section, Developer options and enable USB debug.
How to get into Recovery Mode
1. Unplug the USB cable.
2. Shut down the device.
3. Hold down the 'HOME' + 'VOLUME UP' buttons and press the 'POWER' button for about 5 seconds to enter Recovery Mode.
How to get into Download Mode (For Odin)
1. Unplug the USB cable.
2. Shut down the device.
3. Hold down the 'HOME' + 'VOLUME DOWN' buttons and press the 'POWER' button for about 2 seconds until a WARNING! Screen appears. Press the 'VOLUME UP' button to enter Download Mode.

**FAQ**
Q. Help me I can't find my build in the Model Selection Screen
The Toolkit includes a selection of Insecure Boot Images to cover all the different builds available. As there are very many different builds it is impossible to include an image for every single build but some builds share the same Boot Image. If you have a build that isnt listed on the Model Selection Screen you can therefore use a similar build. The best way to go is up to the next available build as it should offer more compatibility with the build you are using but if that isn't available then try the next build below your one as it should still be almost identical as long as it is the same version (ie. 4.1.2).
The Model Selection Screen is there so that if a task in the ToolKit requires an insecure kernel [to perform adb root commands] and your phone doesnt already include one, a compatible boot image [with an insecure kernel included] can be flashed to provide adb root access.
If you have a Custom Rom flashed to your phone then it will most probably have an insecure kernel included so it doesn't really matter if your build is not listed on the Model Selection Screen and when asked [by certain functions] if you have an insecure kernel on your phone you can answer 'yes'. However if the function fails then your kernel may not be insecure in which case you can flash one from the ToolKit. If you need to do this make sure the right build [or closest available build] is set so you flash the right image for your phone.
----------------------------------------------------------------------------
Q. What is ADB Shell?
Adb shell is a linux command line tool (because android is based on linux) used to send commands to your android device. For S-ON devices, this is crucial for modifying files in the /system partition (where the rom sits) as you cannot modify anything in /system when the rom is running without S-OFF like removing system apps.
----------------------------------------------------------------------------
Q. Why do I need to back up my IMEI/EFS and how do I do it?
There well protected section of your device that is virtually immune to any kind of flashing and manipulation (unless of course you know how to access it). This part of the device contains information such as IMEI (or MEID and ESN in the case of CDMA devices), programming parameters for the device such as your account information (phone number, etc), data provisioning parameters, and a whole bunch of other things that, when not handled properly, can render a device completely useless. All of these are contained in the infamous \EFS folder. If anything messes with your EFS folder, unlike flashing a device (which could potentially lead to bricks as well) it could render your device completely useless as it will no longer be recognized by your carrier. If you are not planning on flashing anything to your device and want to stay on pure Stock then you may never have any problems but it is still advisable to backup this information just in case (better to be safe than sorry).
This feature will be added to the Toolkit after testing has been completed.
----------------------------------------------------------------------------
Q. Does flashing a custom image increase my flash counter?
Any image that is flashed via Odin that has been modified will increase the flash counter that can be viewed in the Download Mode on your device (if booted by holding the Volume Down, Home and Power buttons). You can reset the flash counter using an app by Chainfire called Triangles Away and can find instructions on how to use that in the Downloads section in the Toolkit.
----------------------------------------------------------------------------
Q. Will flashing Stock ROM via odin using the toolkit replace everything that was flashed before? recovery? etc?
Yes a Stock Image flashed via Odin will replace all your key partitions (boot, recovery, system) with the stock firmware. If you want to reset the phone back to an 'out of the box' state then you want to enter recovery and do a wipe first which will reformat your userdata partition.
----------------------------------------------------------------------------
Q. I flashed Custom Recovery but each time I reboot the Stock Recovery is back
There is an auto recovery restore system on certain Stock Android Builds that will reflash the Stock Recovery if you flash CWM on a Stock Rom.
Use Root Explorer to Mount the system folder as R/W (or use a free app from Google Play such as ES File Explorer). Rename the files /system/recovery-from-boot.p and /system/etc/install-recovery.sh (requires root). Now when you flash Custom Recovery it will NOT be overwritten after a reboot. You can also do this via the Toolkit.
----------------------------------------------------------------------------
Q. My AntiVirus program says the Toolkit files may be harmful
The exe compiled files are not digitally signed with a Microsoft certificate (as they cost money) so certain AntiVirus programs (mainly Norton and AVG Free) may pick it up as potentially harmful when it is not. They will pick up ANY file that doesn't contain a purchased Microsoft certificate in the same way. Just Restore the deleted file and exclude it from further scans and it will be fine. Or switch to a better AntiVirus program such as BitDefender.
----------------------------------------------------------------------------
Q. I flashed the Toolkit Boot Image, now my wifi + bluetooth won't work
The boot images are made from Stock with only needed changes made to the insecure boot images [modified adbd, default.prop and rc.local edited] and will work on all stock roms. If you flash them to a custom rom and the rom has been altered or uses a custom boot image then it will boot but certain modules may not load such as wifi or bluetooth. In this case you can use the boot image to root or perform adb root functions but will need to flash back the boot image for the custom rom to get other functions working again. This is not a fault of the Toolkit but a difference to stock in the custom rom.
----------------------------------------------------------------------------
Q. I am having trouble getting adb working with the drivers installed
Try switching your connection type from media (MTP) mode to camera mode (P2P). To do this open the notification area, click where it says connected as and change from MTP to PTP.
----------------------------------------------------------------------------
Q. I want to send my device back for warranty purposes
1. Follow the instructions to reset your flash counter with TriangleAway.
2. Download and flash a Stock Firmware image from the download section.
3. Boot into Stock Recovery and perform a wipe/factory reset
.
Your internal storage will be formatted and data and cache wiped. Your device should now be back to an out-of-the-box FULLY STOCK state with the flash counter [shown if you boot to download mode manually] reset and ready to send back.
----------------------------------------------------------------------------
Q. When connecting the phone I get 'USB Device not Recognized' and no serial number shows in the ToolKit
I actually had this problem recently and what fixed it for me was to make sure that the drivers have been installed, then shut my phone down plug the usb cable in and restart it. The phone booted up and the device was recognized and drivers installed correctly. May not work for everyone but worth trying.

CWM is the experimental port from emwno in *THIS* thread.
I need people to test if the insecure boot image flashes and whether the root process works.

Flashing custom recovery shouldnt affect the boot process have you tried just holding the power button for about 15 seconds to force a hard reboot?
Are there any lights or anything on the screen?

As stated the cwm port is still experimental but it is being worked on by emwno and im sure he will get there.
Has anyone tried the root procedure yet with the insecure boot image? I really need some feedback here.

Hey mskip,i just downloaded the toolkit and went through the insecure kernel process with no problems,tho i had already rooted using the Framaroot app. I also installed cwm and booted into it,although it's a little buggy it's useable ,just need something to flash in it now

Glad its all working ok. Did you go through the ALL-IN-ONE process? Just wondering if you had installed busybox as I need someone to make a NAND backup from the backups section. If you can do that and then post a screenshot of the files (filenames and file sizes) then I can update it to a public version

Glad its all working ok. Did you go through the ALL-IN-ONE process? Just wondering if you had installed busybox as I need someone to make a NAND backup from the backups section. If you can do that and then post a screenshot of the files (filenames and file sizes) then I can update it to a public version

Looks good
Now I just need someone with a full stock firmware flashed that can test the ALL IN ONE process and perform a NAND backup to make sure it works from scratch. Any takers?
Mark.
I will try once I'm home

i use your nexus 4 tool kit a lot and was excited to see this one
i had already rooted via the framaroot app. was able to successfully load up CWM recovery (although it needs some help but i see in the other thread its being worked on).
also ran a backup successfully.

[UB]FOTA TWRP/PhilZ installer APK and Flashable ZIP recovery

F2FS improves the benchmark score in most (if not all) devices by around 20%..
For testing:
I have modified an APK containing Aroma Installer to flash recoveries to fotakernel for our ZR's. This is an initial release..
It contains 2 recoveries.
PhilZ Touch and TWRP with f2fs (TWRP) support which has been tested and working in both Resurrection and Validus builds/ports and should work in all cm11 and CM12/CM12.1 with f2fs working in cm12 after march this year
Install the apk and flash either Philz or Twrp through the app in the drawer..
And no, this is not Xperia Recovery manager.
The recoveries are both contained in the app so making it 22MB to download.
The TWRP 2.8.7.0 has new graphics and f2fs support
PhilZ is stock 6.57.9 cwm v6.0.5.1 shared by @uncomment
Download APP here (contains the 2 recoveries mentioned above): Removed because of bugs.. will fix and upload to new link..
TWRP 2.8.7.0 f2fs with updated graphics flashable zip: https://drive.google.com/file/d/0B3slVcYWwXQ-RjNKUDhWWk5OemM/view?usp=sharing
(This is the latest recovery from TeamWin with their new blue theme.. I personally didn't like all that blue so I changed the images.. See screenshot below)
Philz Touch 6.57.9 flashable zip:https://drive.google.com/file/d/0B3slVcYWwXQ-MEd4TU1vb0NYcmc/view?usp=sharing
Flashable ZIP stock TWRP 2.8.7.0 with f2fs:
Put the zip in you sd card and flash through recovery.. This will push the twrp 2.8.7.0 f2fs to your fota kernel, reboot recovery after flash...
Download: https://drive.google.com/file/d/0B3slVcYWwXQ-YTB6V1N0eEx5SU0/view?usp=sharing
Please test (recovery.img)
UPDATED TO TWRP 2.8.7.0
Download here: https://drive.google.com/file/d/0B3slVcYWwXQ-SjJRRjdyZ2pzeXc/view?usp=sharing
Instructions are the same as below...
This is TWRP 2.8.6.0
Download here:
https://drive.google.com/file/d/0B3slVcYWwXQ-Q0pEYzlFSjhPNFk/view?usp=sharing
Place the recovery.img (it is named twrp.img when you download but rename to recovery.img) to you internal storage and use adb or emulator (download Android Terminal Emulator free from Store) commands to install to your Fota:
su (enter and grant root access if using Emulator)
dd if=/sdcard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel (enter)
If you use Xperia Recovery Manager app by @championswimmer, rename the recovery.img to twrp.img and put in the TWRPXperia folder on your sd-card and flash to Fota through the app. Confirmed working.
If the image doesn't install correctly, please flash this hack:

Only cache and data/ ext-sdcard is convertible for now, if you try to convert system, you will brick your phone..
Use the following method to convert:
Convert to f2fs by pressing Wipe > Advanced Wipe > select the desired partition > Repair or change filesystem > Change filesystem > f2fs
Some added info by @nostupidthing
with f2fs twrp installed, i've changed /cache and /data into f2fs without wiping. you just have to backup /data, then format it as f2fs, click "use rm-rf instead for format" in twrp settings, then restore /data.
If any one is looking for a theme for twrp recovery, i found an excellent theme here: http://forum.xda-developers.com/android/themes/theme-twrp-materialised-dark-light-play-t2915584
(Download resolution 720x1280 for ZR)
As an added service I am willing to personalize the splash screen at recovery start-up should you have any request ie your name, flag etc but i will insist that "TeamWin" will be present somewhere on your personalized splash.. After all, we all benefit from their hard work.. Do not expect your request to be done within the hour but periodically check and i will upload and link as and when you request is done..
Massive thanks to @uncomment and @o-l-a-v and @Olivier and @blastagator and @qsnc including @nostupidthing for testing and for making this possible. @SdtBarbarossa for the app!!
the "now changing the microsd to f2fs" is not necessary for /data & /cache. you may or may not like to do it, and i ended up not doing it because copying my several gbs of files out of the microsd takes so much time and i just gave up..
but if anyone wants to do it, basically you just copy the files to your PC, then format the microsd to f2fs, then copy the files back there.

I agree with you.. I have formatted my ext sd card but like you said, took ages to copy the content to pc and back again.. In my opinion not worth doing if anyone, like me, use the ext_sd card for storage of music and downloads etc.. Cache and data absolutely worth doing tho.. A great many thanks for your comments and help doing this..
sent from Paul's phone
one more thing. backing up /data via twrp will not back up your "internal sd" files, like camera photos if you store them internally instead of on the microsd, so you have to copy those yourself as well.
Added flashable zip to op... Should make things easier..
the 2.8.7 flashable zip works, bro. thx.

Great
BTW, I would suggest you to set TWRP's file manager to open SDCARD1 by default instead of SDCARD0, if possible, or even both to let users choose. I'm not sure if this is ROM or Recovery dependent because it worked this way through the latest Validus ROM. I'd bet on the recovery side though.

It's party of the recovery but a few spaces down from the top in file manager is external_SD and a few spaces lower is SD_card so should be easy enough to find the way around..
BTW I've made new images and things for twrp which makes it a little easier to see but I'm waiting for permission from someone as I used their ui.xml to make that.. Will be added as soon as

What kind of apps were removed? and can I go back to normal if I dont want this backup anymore? will it erase all my data?
my worthless T-mobile one refuses to enter recovery
wont work too vague

Your asking 2 questions thinking they are related. The rom is unlocked meaning you can change it if there was a rom for it bootloader is unlocked so tou can modify the recovery bit sim lock is another thing they are not related in any way shape or form. If tour asking id it can be sim unlocked then yes it can be but that proceas is not like flashing a new rom to make that part work sim unlocking would work on the ohone on stock or not that just depends on who you got the phone feom like tmobile or metro tjey have presequets on how to sim unlock or you pay someone to do it for you
So in other words just because you have custom recoveey or rom or not sim unlocking is another process that has nothing to do with the phone being stock or not if that makes any sense
Thanks for the answer. Do you know how or who can remove sim lock from a K20 Plus? The original network is MetroPCS.

Backups need to be i in twrp/Backups/LGxxxxxxxxxx (model/serial of phone) folder for twrp to see them, not on root of sd card.
If you haven't made a twrp backup, just do a backup of boot to create the proper folder and copy the 2016-12-31--20-18-59_NRD90U folder from the downloaded zip into it.
Thanks, now I am having another issue, I think I can resolve it I can't get twrp to mount /system rw so restoring backups is failing.
Is anyone else having this problem? What I did to fix it was open terminal in twrp, and type "mount -o rw,remount,rw /system" which seems to have worked, this was after installing the no-verify and a SU

You have to create a new backup folder , containing only one item. And then take the file that you have of all your real backups , and put it in that spot , if ur backup location is SD card , then this can easily be done useing Sun 3.0 micro SD card reader , or other method. The TWRP will see the file then. If ur backup is in internal memory , u just do the same thing. Useing minimal adb and fastboot (fromXDA). Otherwise TWRP will not see the backup file. There r a couple of videos on Utube as well , that cover this process.

Yes did that, got that sorted, thank you, I was asking specifically about if anyone else had system that was Read Only, would not allow Read write.
Is this based on a stock Google rom? I'm about to be getting this phone tomorrow through Metro, but I hate the LG UX UI and would rather it be vanilla Android 7.
Worked for mine but xposed makes it boot loop...

[Recovery][Stock OOS]Oxygen OS Stock recovery with ADB enabled

While waiting for a working TWRP for all those needful of the possibility to access their file system from recovery, e.g. for removing an offensive magisk extension preventing boot I repackaged the Stock OOS recovery but with ADB enabled.
Prerequisites:
Oneplus 8 Pro
unlocked bootloader
access to fastboot on the phone
adb and fastboot
Installation:
Reboot the phone to fastboot, then flash the recovery from fastboot with the command
Code:
fastboot flash recovery <filename>
(with <filename> being the name of the recovery in the format of "recovery.img" you wish to flash)
Uninstall:
Same as installation, but flash the original stock recovery instead.
Usage:
Boot up recovery, enter encryption key if file system is encrypted. Then connect the phone to PC and you are ready to go with adb. E.g. by using
Code:
adb shell
to open a shell and access the file system. Magisk modules are located in /data/adb/modules, deleting the corresponding directory there will remove the module in question.
Step-by-step this would be:
Code:
cd /data/adb/modules
to change to the Magisk modules directory
Code:
ls
to list the content of this directory, each module has its own directory, usually with a well-recognizable name
Code:
rm -r <directory>
to delete the directory in question. Tip: in console TAB-autocomplete works
Downloads:
10.5.4 BA Recovery
Modified 10.5.4 BA recovery from GDrive
Original 10.5.4 BA recovery from Gdrive
10.5.5 BA Recovery
Modified 10.5.5 BA recovery from GDrive
Original 10.5.5 BA recovery from Gdrive
10.5.6 BA Recovery
Modified 10.5.6 BA recovery from GDrive
Original 10.5.6 BA recovery from Gdrive
Notes of caution:
ADB security is disabled as I could not get the recovery to allow for authorizing a connected computer. As a consequence any computer connected is automatically authorized in ADB, although with encrypted filesystem at least no data is accessible without the key.
with direct ADB access to your file system you can easily wreck you phone requiring a factory reset or even reinstallation of the OS from fastboot - please be careful on what you are doing
Credits: Thanks to osm0sis for Android kitchen and all great developers for the Oneplus devices, specifically mauronofrio for his TWRP efforts.
Description of method to modify recovery by yourself:
Prerequisites:
Android Image Kitchen (credit to osm0sis for providing this tool)
the original recovery image file (henceforth called "recovery.img"). You can extract this yourself from an update zip file by unpacking "payload.bin" and then use a tool like payload_dumper (credit to vm03 for providing this) to extract the recovery.img file
Now do the following:
unpack image with Image Kitchen --> this will create a "ramdisk" and a "Split_img" directory with the unpacked content within
navigate into the "ramdisk" folder and use a text editor (on windows preferably Notepad++) to edit the file "prop.default"
look for entry "ro.adb.secure" and change entry value from "1" to "0". Note this entry can occur multiple times (I noticed twice), change each --> this will prevent adb from asking for authorization (the recovery does not provide such a dialogue)
look for entry "ro.debuggable" and change this from "0" to "1" --> this actually enables adb
look for entry "ro.secure" and change this from "1" to "0" --> may be unnecessary but I wanted to avoid brick in case a modified recovery would result in such a behaviour
save textfile
repack the image with Android Image Kitchen and voila:
you have a new modified recovery image you can flash
Thanks for this...
On fastboot we have to flash the modified recovery img?
EDIT : Nevermind haven't read the whole OP
I have a noob question: this won't affect data or magisk right?
To remove a module , command should not be :
( rm -rf < directory> ) ?...

Thanks for your comment, but technically no
The - f flag is used to omit prompts before each removal, which may or may not be helpful - depending in how sure the user is on what he does
I chose the safer variety in my example, confident that users with more knowledge can always look at the "rm" man page to decide what command they want to use...
But again thanks, I do appreciate your help!

Correct, the recovery resides in a separate partition and flashing it doesn't do anything anywhere else.
In fact the recovery looks and behaves the same when booting into it, the change only becomes apparent by being able to use adb in recovery.
@s3axel can we use this recovery to escape bootloop due to install unsupported theme or any issue from substratum?
Or maybe just flashing stock boot IMG on fastboot is enough...

It should be possible as the recovery gives you full access to your file system and so, given you know what to remove/change, it should also be possible to recover from issues as you mentioned.
My problem: I have no idea where themes or substratum additions are installed directory-location wise, will need to research a bit. Or maybe someone else can chime in on this, then I could update OP with info on that as well...
Ok one more question..
Can we flash zips through the recovery?...
Via ADB sideload?.. maybe..

Because on pixel4 XL you can reboot to stock recovery and choose the the option ADB sideload...

What an incredibly helpful response. Sorry but if there's something that'll decrypt and allow me to backup and recover, of course I'm going to try and find it. And I suspect most other people here would too.

I don't know presently, usually I compare recoveries or I (or other users) add recoveries for other regions which they made by themselves. When recoveries are the same of course they can be used
RIght now I cannot download the 10.5.5 AA firmware (download aborts after some time), I'll add the recovery once this is working... EDIT: seems OP pulled the downloads, so no luck at the moment...
If there is a working twrp in China then perhaps it's worth making contact with them to see if either:
A) they can let you have it
B) they can help you fix this one?
It's presume the former would make the most sense, with permission I see no problem in obtaining it or linking it, certainly not taking about it. Makes no sense to just avoid an obvious assist whilst we all struggle without twrp.

[ROM][SM-T500] Samsung Galaxy Tab A7 10.4 (2020) - LineageOS 18.1

Update: March 24 2022: This ROM has been retired and a new one based on LOS 19.1 (and TWRP based on Android 11) have taken its place. New thread here: https://forum.xda-developers.com/t/...4-2020-lineageos-19-1-and-twrp-3-6-1.4421365/
---
Update 9:46am EST July 15 2021: new builds of TWRP and LineageOS with TWRP touch fixed and LOS w/ space for Gapps is now live.
WARNING: USE AT YOUR OWN RISK.
I have successfully ported TWRP and Lineage OS 18.1 to the Samsung Galaxy Tab A7 10.4 (2020), aka SM-T500. This is my first time porting TWRP or LOS, so there may be issues unknown about at this time. Thus far, the only known issue is that the touchscreen in TWRP does not work. This can be worked around by using a USB mouse and/or accessing the device via ADB.
Here are the steps to follow:
Update your device to the latest stock ROM (as of this writing) either using the built-in system updater or via Odin. You want the build that ends with "3BUF3".
Unlock device bootloader using instructions from other threads. This will wipe your device.
Boot into download mode and flash "vbmeta_disabled_R.tar" via Odin in the "Userdata" slot to disable verified boot. This will wipe your device again.
Boot device back into download mode and flash TWRP via Odin in the "AP" slot. If you boot up into the stock ROM rather than booting directly back into download mode then go through the initial setup process of the stock ROM and enable developer tools and ensure OEM Unlocking is still enabled (VaultKeeper can possibly undo OEM Unlocking if you get to the ROM but don't go into Developer Tools and view OEM Unlocking is enabled, so make sure to do this).
Boot device into TWRP (recovery mode) and format (not wipe) your data partition. Then reboot back into TWRP.
Push LineageOS (super.new.ext4.img) to device. Ideally push it to an SD card formatted with ExFat or EXT2/3/4 (FAT/FAT16/FAT32/VFAT won't work due to file-size limitations).
Install LineageOS image to "Super" partition. Make sure to select "Install from Image" in order to show .img files in the install selector screen.
(Optional) Push NikGapps Omni to your device and install the zip. Make sure you include a "nikgapps.config" file in your "/tmp" folder that is configured to install to "system" rather than "product" or "default".
Reboot to system. You should now be in LOS with Gapps.
(Optional, but recommended): Install Magisk via TWRP
(Optional, but recommended): Run fix script to fix brightness slider not working and to make Magisk work. If you didn't install Magisk but only want the brightness fix, just enter "n" when prompted in the script. To run the script:
NOTE: Script has .txt file extension to allow hosting on AFH. Remove that so it's just .sh to match the instructions below.
Download and push to device when booted into TWRP
adb push sm-t500_fixes.sh /tmp
Enter an adb shell
adb shell
Change directories and set permissions
cd /tmp
chmod +x /tmp/sm-t500_fixes.sh
Run script
/tmp/sm-t500_fixes.sh
Tips:
If you are not seeing all of your storage space in the OS on the internal flash, boot to TWRP and format data.
Flash TWRP via "AP" slot and flash VBMeta_Disabler via "Userdata" slot in Odin.
Flash LineageOS as an Image, not as a Zip.
For Gapps, use the latest NikGapps for ARM64 and Android 11/R.
For Gapps, make sure you install to the System partition and not Product. To do this you need to slightly modify a nikgapps.config file. Instructions on that can be found on the NikGapps site.

I have successfully ported TWRP and Lineage OS 18.1 to the Samsung Galaxy Tab A7 10.4 (2020), aka SM-T500. This is my first time porting TWRP or LOS, so there may be issues unknown about at this time. Thus far, the only known issue is that the touchscreen in TWRP does not work. This can be worked around by using a USB mouse and/or accessing the device via ADB.
Here are the rough steps to follow:
Unlock device bootloader using instructions from other threads.
Patch stock ROM (AP) using Magisk, then flash rooted ROM. Will likely need to wipe device after this.
Boot into rooted ROM and ensure "OEM Unlocking" is still enabled in "Developer Tools".
Boot back into download mode and flash "vbmeta_disabled_R.tar" to disable verified boot.
Boot device back into rooted stock ROM to ensure things are still functional (may require a device wipe at this step).
Boot device into download mode and use ODIN to flash TWRP recovery.tar file via "AP" slot.
Boot device into TWRP to verify functionality (hold Vol-Up + Power during boot).
Access TWRP via adb using "adb shell" or with USB mouse (touch functionality currently not working).
Format data partition on device.
Via ADB shell: twrp format data
Via USB mouse: Wipe -> Advanced -> Format Data
Boot device into download mode.
Via ADB shell: twrp reboot download
Via USB mouse: Reboot -> Download
Flash LineageOS tar file via ODIN using the "AP" slot.
If device boots into TWRP after flashing LineageOS, use USB mouse to select: Reboot -> System
Device should boot and stall for ~1m at the Samsung logo screen with red text below, then should go blank and then display LineageOS boot image.

Great news!! But I think you need to post it in the ROMs, Kernels, Recover thread.
awesome. Will try after work. Also I think you posted in the wrong section.
Which slot to flash the vbmeta?

AP
Thanks,
After flashing the vbmeta it booted into recovery automatically after what looked like a bootloop in progress, so I wiped with factory reset and then it rebooted fine. (still not sure exactly what the vbmeta does I was hoping it would make it so i didnt get that stupid pop up asking me to hit power button to continue booting due to it having the patched os) anyhow booted fine and twrp installed as you stated without touch screen but mouse with otg works fine. (great job so far) On to LOS... I think I should have checked oem lock before flashing LOS as when I installed I get stuck at boot screen that says oem lock is on... must have been from my factory reset... (facepalm)
Nope... Still sticking on boot with the following showing on the screen...
RPMB fuse not set
RPMB Provisioned
Current BInary: Custom (0x30f)
FRP Lock : OFF
OEM Lock : ON (U) {this was off verified before flash}
KG Status : Checking
Waranty Void : 0x1 (0xE02)
Quallcomm Secureboot : Enable
RP SWREV : B3 (1,1,1,3,1,1) k3 s3
secure download : enable
grdm status : normal (d0000501)
did : 041ce2d22dba
this is displayed in the corner on the bootscreen and looks like it belongs on the download screen, anyhow booting into twrp from this point works however factory reset fails with unable to mount key(something and key(something else) i figure i will let it sit a while as I know sometimes it just takes first boot a while to go through however it doesnt seem to be the problem. Have you had a positive install of the LOS? I am wondering if I had maybe gotten a bad copy of the file. When i go to install I get a pass in odin so not quite sure where to go from here other than back to the factory image any help to get this going would be great... I took on this task cause i needed someting to take my mind off the severely crappy week I have had... so looking forward to anything you can share here...
Actually, userdata is the slot I always use. It might work in both though.
Something to mention: there is not enough space on the /system partition to flash Gapps. I created a build that supports it (with a resized /system partition) but I couldn't get it to flash via Odin. The only way I got it to work was by flashing it via TWRP as an img file. I will be posting that soon. Unfortunately that will be the end of development for now as I hard-bricked the device and need to wait for a repair or replacement. Should be back developing in 2 weeks.
Nevermind what I said here.

You may need to get an otg cable for a USB mouse and choose "reboot system" from the gui. Alternatively, look at the /dev/block/by-name/misc partition and try blanking that out with dd. That has worked sometimes.

Also, from an adb shell, try "twrp reboot". Supposedly that should boot to system, but I feel like in testing I got mixed results. According to the TWRP documentation though that should be the answer.

I was able to use adb to run the TWRP Format Data command and it rebooted the tablet and now LOS has booted up. I think I'm good!
Looking forward to see how this develops
Rom is fast and snappy. Brightness control does not work. I haven’t played too much because of work but that’s what I’ve found so far
Can a mod move this to the rom release section?

I've not been able to flash this yet but I know that the latest TWRP versions have a way to fix the system partition to accept gapps. /Wipe/Advanced check system then resize. Sometimes you have to do it more than once if it is a large gapps.

I will look into that, but I'm not optimistic it will work. This device does not separately present the system partition, rather it uses a super partition which contains system, vendor, product, and odm. TWRP only shows me the super partition for working with. I was able to resize the system partition by expanding the Lineage image and file system on my pc to match the original stock system partition, then rebuilt the super image with the other partitions it needs.
