I have rooted my m10g using magics via twrp and also applied the "no-dm-verify" patch but I didn't notice about the "forced data encryption" patcher here so that's reason why I didn't patch it at this point! anyway the data section was mounting without any problems but after I reboot recovery I was getting error In mounting the data section I just ignore it and I was able to boot into system normally but after some days exactly after "insufficient space" I just rebooted for some reasons and after that the device won't boot anymore / stucked at bootloop...!
I was able to see the home screen/touch wiz about 4 seconds and after that it's reboots again and again (In this point I tried to delete unwanted files quickly but there's no luck).
Things I have tried:
- flashed an recovery.img extracted from combination firmware and tried the "lacking storage booting" an option from stock recovery menu the device started in safe mode (It's says something like this: please bacup your stuff and then perform factory reset) but it's still won't boot (bootloop).
- twrp decrypt (I set no password there but I just tried In hope of chance) btw twrp never asked before to decrypt my data or to enter any password.
- I did twrp backup to my ext-sd and decompiled the boot.img to see what can I do (but after magics's patch I can do nothing).
- Pulled full userdata (mmcblk0p26) section also the emmc (mmcblk0) and tried to mount via linux reader windows tool / opening via 7zip but still can't access the userdata section. also tried to open the dumped userdata via hex editor but still can't see anything(looks like encrypted).
Things I want to try next:
- Format the data section after that try to restore the dumped userdata section via dd command.
- Enable usb debug at boot time and try to adb shell stop then pull all important data from the device.
- Inject custom script in stock_recovery.img to copy all internal files to the externel-sdcard (or even delete some huge files that I'm pretty sure of their path).
Notes / just to be clear:
* Flashing the stock kernel will encrypt the userdata section and the bootloop will stop but I'll lose all my data (I know that so I was just switching from the stock recovery to twrp).
* I could just perform a format data from the recovery menu / twrp or just flash the stock firmware to fix the booting problem but first I need to all my files get back.
Looking for any help in things that I want to try next.
Finally after a lot of tries I have solved my problem...!
How?
Short answer: ClassyKitchen
Long answer:
I just started creating my first rom In ClassyKitchen and I just enabled adb and removed dm-vertify via the kitchen and after the rom has prepared I just flashed through TWRP after I reboot the phone wasn't able to boot (stucked at first samsung logo) switched the device to download mode and I flashed system only using odin... after that phone started with setup wizard! and it's was still in safe mode (the backup message was still showing also) anyway I completed the setup wizard then check the home screen and apks I have installed wasn't there...!!! I opened "My Files" and finally I was able to see my files again!
I just copied all my internal sdcard to my external sdcard...!
After the copy ends I tried to exit safe mode to get my installed apks/contacts again so I just rebooted the phone to exit from the safe mode! But after the reboot "custom binary flashed bla bla".
I flashed stock "boot.img" and "recovery.img" using odin But as I said in the first post data encryption was there...!!!
Anyway I flashed full stock firmware after that I unlocked my OEM and flashed TWRP again and I restored the emmc dump using dd after restore completed rebooted the phone and it's back to it's state...!
this time I just flashed the patched boot.img (ClassyKitchen) and after the reboot phone started normally with setup wizard as said above! Connected to wifi unlocked my OEM and I was trying to get out of safe mode I rebooted and rebooted and power off but I wasn't able to disable the safe mode...!!!
I tried to root using magics but it's failed (the boot was patched by bla unsupported something like that) also the data section was still unmount able! In the TWRP
Anyway I just stopped at this point! Because I have reach my point (Getting back my sdcard data).
Notes!:
* All thanks goes to the author of ClassyKitchen.
* TWRP I was using found here.
* Odin I have used found here.
* I was using the same firmware version (PDA) installed in my phone.
* I have unlocked my OEM using this method the first time I have used it's taked from me only 3 days!.
* The idea of taking full encrypted emmc backup was by this post (I was getting some error messages so I just used "dd if=/dev/block/mmcblk0 of=/your_external-sd/mmcblk0.img" In case of "no space left error" format your externel-sdcard to ext4 and try again).
Sorry for my bad English x).

Hello,
Problem - Device keep on rebooting showing Mi logo (every 2 sec), Does not boot into system
What I did?
exteneded system partition to 1.2 gb - success
flash Marshmellow custom rom - success
misinstalled system ui of theme - system ui stopped
reinstalled clean rom from custom recovery - success
then it does not boot into system - keep on rebooting at mi logo (every 2 sec)
tried fastboot rom - failed (remote size too large)
rebooted into recovery
flash stock partition via adb - success
fastboot flash (with flash all) - success (says miflash - operation compeleted successfully)
Still it does boot into system - keep on rebooting at mi logo (every 2 sec)
Help?
if you can access recovery now then go to recovery and take a backup of current rom. The wipe everything except internal storage and then restore the backup.
maybe it'll fix it because thats what happened to me too after flashing the MM custom rom. Every time i was rebooting the phone kept bootlooping at Mi Logo.
Hmm i ll try but i have to install twrp from adb for backup.
Cwm backup not promising.
You think there ll be problem in hardwere?
No problem in hardware.
and yes do it twrp only. never try cwm.
the thing is i am not able to enter into recovery mode at all.
No recovery and fastboot accessible.
Then connect it to PC and tell me what name the device manager shows for the device.
fastboot is accessible.
i've flashed fastboot rom from miui. successfully completed. but it won't boot.
yesterday it booted into system so i was charging the phone, as soon as i removed charger it went the same boot looping.
now,
clicking flash_all_except_storage from fastboot command
it shows one line in every process - 'target reported max size 80909989 '
process goes on and success.
but does not boot into system. same bootloop.
one strange thing is,
when i connect to pc, - just by pressing vol down button i'm entering to fastboot. (even without holding power button)
does this mean there's something wrong with power button which causing cont. reboot? i mean it cont. forcing system to on and off? :s
Nothing is wrong with the hardware. In this situation the phone boots into fastboot by pressing vol when plugged in.
You didn't answer my question. What does it show in device manager on PC.
sorry for late reply , net connection loss
device manager
1st one is android booloader interface
other devices - bluetooth peripheral devices
Did you use miflash tool to flash fastboot rom
yes,
flashed successfully says miflash.
While flashing using miflash did you select all files in advanced menu properly.
Like all the bat, mbn and xml files.
i didnt try all the file separatly.
trying now.
Then go to advance and choose all the respective files properly.
1st one - flash_all_except_storage.xml
2nd one - nvflash_all.bat (leave it as it is)
3rd one - MPRG8974.mbn
4th one - 8974_msimage.mbn
5th one - rawprogram0.xml
6th one - patch0.xml
i found
flash_all.bat
could not find nvboot script
flash programmer
boot image
could not find kernelflinger image
could not find UFS provision image
RAW xml file
patch xml file
should i go with files?
Which MiFlash tool are you using.
I used the 2014.05.09.0 version
Try this one.
And extract the fastboot ROM twice till you get the images folder inside the "cancro_images_V7.0.****" folder. There you'll fill all the files.
Then in miflash click browse and select that images folder.
And in advanced options select the respective files which are there outside the images folder.
2015.10.28 version
i ll leave the navboot as it is.
giving it a try.
appreciate your help brother.
If it doesn't work then try my version.
It has proper names of files. To avoid confusion.
And all files are there in fastboot ROM except nvboot
i checked on miui
no halos.bin
tz.bin
these all files?
p.s.
operation completed successfully but same boot loop.
trying your version now.
So, i was flashing cm13 and everything went well until i did something stupid. I accidentally wiped the newly installed system because i thought it said 'wipe system cache' but it said 'wipe system' only. I was using cm recovery. I erased the zip file after i flashed so i dont know what to do anymore. Please help me!. i can still go into recovery and fastboot mode and thats all....
Push a ROM file through adb. In TWRP, there's an option called "adb side load". Use that.
Or mount OTG in TWRP to flash a ROM.
if you have TWRP, just turn it on using the specific combination of the keys. Then directly connect to the pc using the data cable and it will show the internal storage of your device. Copy the cyanogenmod 13 from your pc and flash it. Peace!!
Download tool in original android development thread and go into fastboot mode connect to PC and in tool chose option flash cm 12.1 .....it Dow. Required files than flash it by enter
And its done
Os file is approx around 1gb
Dear friends I need help!
I've tried to flash my tablet but I've got an error message while flashing Katkiss 6.0
What I did:
downloaded Rom.(md5sum is OK)
my bootloader is ww_epad-11.4.1.17-20140711
recovery CWM v6.0.5.0
previous rom zoombi pop
/format data
wipe data factory reset
install zip from sd card. (from internal storage or micro sd card)
And I have got the following error (in attachement)
Please help, my tablet boot only recovery now.
Thanks in advance for the help
trying to boot in fastboot mode when children let me try that...
Edit: fastboot ok.
I placed the the files
KatKiss-6.0_TF701T_033.zip
open_gapps-arm-6.0-pico-20170120.zip
UPDATE-SuperSU-v2.79-20161211114519.zip
In
C:\Program Files (x86)\Minimal ADB and Fastboot
ok I don't know how to proceed now.
Seems I cannot change the recovery from CMW to TWRP,
My bootloader is 11.4.1.17 and the tutorial to install TWRP says in capital red:
MUST BE ON A BOOTLOADER 11.4.1.27, 11.4.1.29 or 11.4.1.30
So how can I do?
I there a way to upgrade the bootloader to be able to install TWRP?
Or should I Flash the custom rom from fastboot?
My TF701 in not booting anymore.... only bootloader and recovery CMW
the positive thing is :
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
15C3E10090400000011FA8580 fastboot
Please help
I have been able to flash CROMI X (unfortunately with strong battery drain) so CMW is able to flash but for some reasons not Katkiss 6.0.
I have been told that my problem is not ROM related... So it is recovery related?
What is the better option to get katkiss on my tablet? Flash the recovery to get TWRP even if my bootloader is 11.4.1.17 and the tutorial to install TWRP says in capital red:
MUST BE ON A BOOTLOADER 11.4.1.27, 11.4.1.29 or 11.4.1.30????
There is a technical reason about this warning?
Edit: I found this on an old post:
You can try this:
Download the stock recovery from here: http://droidbasement.com/db-blog/?p=3210
Copy the image to your fastboot folder.
Download the Asus firmware, unzip the file once and copy it to your internal SD.
Boot tablet into fastboot
Issue this command
Code:
fastboot boot recovery.img
Note: Do not flash the recovery, just boot it.
It should recognize the firmware file on your tablet and flash it.
Click to expand...
Click to collapse
Would this method work to get the latest stock rom from Asus?
Got your PM and will try to find some time at work today. Hang in there and don't do anything to make it worse
Ok, work was crazy busy so it took a bit longer.
If you flash a recovery that is incompatible with the bootloader nothing happens. Until you use the recovery... That could permanently brick the tablet. So heed the warnings, they are there for a reason.
Ok, let's try to get you on the latest bootloader. It's no suprise at all that nothing boots if you try to flash a Android 6 rom on an Android 4 bootloader....
Download either WW or US package from here: https://forum.xda-developers.com/showpost.php?p=61045480&postcount=2
That zip contains the latest bootloader and a compatible TWRP recovery. Flash the zip in your current recovery just like any rom, then reboot.
When you flash a bootloader or recovery you actually write those files to the staging partition. On the next boot the bootloader will unpack it and write everything to it's proper place.
So it's essential that you flash, then reboot. Does not matter that the boot does not go anywhere. The first part, flashing the contents of /staging to it's partition(s), will happen anyway.
You should see a brief blue bar filling up when that happens. It does not take long.
Boot back into fastboot and check your bootloader version.
Enter recovery through RCK and that should be TWRP now.
Then format /data. Do not wipe it, format it. Do not interrupt it. Wait for it to finish even if it takes an hour (a full battery is a must before you start this). The format command is under the Wipe menu.
Unfortunately the formatting in this kanged TWRP is pretty buggy, but I still like it better than CWM.... If you get lots of error messages after the format (cannot mount this, cannot mount that) go into Wipe > Advanced > select Data > Change or repair file system > Change file system > choose ext3 and execute
Note: The button you have to swipe is pretty "sticky". Swipe it slowly and fully
Reboot to recovery
Go back into Wipe > Advanced etc and change the file system back to ext4
Reboot to recovery
Now everything should be ok, try to mount/unmount data.
Finally you are ready to flash Katkiss
If the bootloader flash does not work, we can try to flash Asus firmware in fastboot, but try the above first.

Thanks a lot to take time to help me.
Will try that tonight and I'll let you know the result.
Thanks a lot!
It was just like you said.
I had to format to ext3 and ext4 because I had errors.
Battery seems to be very good. Just the screen display is very white, needs color saturation and contrast I guess...
Thanks again you save my tablet.
Now that's what I like to read! :cyclops:
Hi everyone. Got a puzzle for you forensic data recovery guys out there. I am a fool having a bad day today. For the first time in 10 years of screwing with Android, I backed up my ROM with twrp and also backed up my sms and calls, but then managed to somehow forget to copy those files off the internal storage before trying to flash my phone to LineageOS and botching the internal storage. Here is what happened.
0) Before state: Rooted (I think) and for sure running OxygenOS 5.0.3, flashed via TWRP. TWRP version 3.2.1-0. 128 GB OnePlus 3T
1) Backed up System, data, etc to backup on internal storage via TWRP. Booted into OS and backed up SMS and calls to .xml file.
2) Wiped data, system, cache and dalvik/art cache.
3) Downloaded LineageOS w/ microG via zip in TWRP and attempted to install. Received error that I needed to update the modem to at least 9.0.3.
4) Mounted storage from TWRP and copied in Stable9.0.3+Firmware+Modem_OnePlus+3T.zip. Ran the install and was successful.
5) Installed lineage-17.1-20200826-microG-oneplus3.zip via TWRP. Left prompt to install TWRP checked and booted into OS.
6) Upon boot, saw the message: "Decryption unsuccessful" The password that you entered is correct but unfortunately your data is corrupt.
7) Rebooted back into TWRP to mount storage. Could not get anything to mount because it would not accept my decrypt passcode.
8) Figured TWRP bug, flashed twrp-3.4.0-0-oneplus3.img via fastboot. Could decrypt now with passcode but all storage read 0MB
9) Flashed modem back to OnePlus3T_5.0.3-25-05-18-FIRMWARE-flashable.zip via adb sideload method which is what I assume I was running before since that was the OS version. Rebooted
10) Booted back into TWRP, discovered I still couldn't see files. Downgraded TWRP back to 3.2.1-0 via fastboot.
11) Unable to decrypt from TWRP or even install zips. No change at any point in the OS. Flashed TWRP back to 3.4.0.0.
12) Ran adb shell twrp decrypt XXXXXX (where XXXXXX is my pin) which gave me this message:
Attempting to decrypt data partition or user data via command line.
(then it returned to shell so I assume it worked)
13) Ran an ADB pull command (adb pull /dev/block/dm-0 backup.img). There is obviously something there because it downloaded 111 GB worth of .img file (which I'm 99% certain was the amount of space I had used on the phone). Tried to open the .img file with multiple EXT4 programs and they all said the file/partition was corrupt.
14) Tried to wipe data via TWRP. Failed to wipe because it couldn't be mounted. Followed this:
https://************/how-to-fix-twrp-unable-to-mount-storage-internal-storage-0mb/
15) Ended up with MTP mount of 101 GB free space. Everything seems to be lost on the phone at present. No programs I use to recover the data off the MTP mount (just doing a raw file scrape) can see it as a OnePlus in Windows.
After finding a better guide on XDA, it sounds like this is a known issue that happens when you go from 5.0.x to 9.x on this phone where your encryption breaks and you lose all files. Unfortunately I saw that about 15 minutes after step 14...
My next thoughts would be to:
a) downgrade everything (ROM, firmware, etc) and then try to push the 111 GB .img file back to the phone via ADB, then flash a stock OnePlus 5.0.3 ROM over it to see if I could get the internal storage to mount again. Don't even need to boot into the OS--just to get the internal storage mounted again through TWRP.
--OR--
b) convert the .img file to a .raw and then possibly a .vhd and use Recuva or something to scan the image of the phone and see if I can find those .xml files and maybe a twrp backup if I'm lucky. Although if the entire .img contents is still encrypted and not actually just a corrupt android filesystem, I think I am hosed on this option.
I would prefer option a) but I didn't know if anyone had any insight on this. I thought maybe there would be a way for me to get into the filesystem via ADB maybe and clear out some botched encryption cache or keystore/etc in order to get it to mount again. I'm also not sure if you're able to downgrade the firmware or modem either from 9 to 5 (even though I never got errors on downgrade). Thoughts? Am I just royally hosed?
Tried option b. Nothing but garbage. I made a backup of the .img file this time... so still would be willing to try option a) unless anyone thinks that this is impossible.
Edit: yep... may be too late... https://forum.xda-developers.com/on...-9-0-3-5-0-8-firmware-barrier-t3941164/page18
To my knowledge the data partitions content is unrecoverable lost after the reboot from 5) to 6). The img contains the messed up (and still encrypted) dm0 container but without the enctyption footer which is "outside" the dm0 container in sda15 (aka userdata) partition. To decrypt the img you are missing the device dependent key (an encrypzed partition can be decrypted only on the device the enctyption has been done on) as well as the encryption footer (which is messed up after the reboot).
Format data (not only wipe!) and start over.
Thanks for the reply. That makes sense and is what I was afraid of.
I wonder if it would be possible to regenerate the crypto footer by doing something like this to get the HMAC keys and then flashing a rom to recreate the cryptofooter and then editing the key values to reflect the old cryptofooter values based on the KeyMaster extraction via this exploit.
http://bits-please.blogspot.com/2016/06/extracting-qualcomms-keymaster-keys.html?m=1
It might depend on how much of the cryptofooter is left and whether or not 5.0.3 is vulnerable to these CVEs...
I’m not sure if I know enough about the KeyMaster structure to know how to rebuild it even if I were able to retrieve the HMAC keys.
I also know TWRP now supports EDL so perhaps there is something with a Qualcomm tool I could yse to assist.
Obviously this would mean security issues for everyone on these older builds if I am able to regenerate the crypto footer.
Are you aware of adb commands or likewise that I could run to survey the KeyMaster damage?
As stated: to my knowledge the data is lost after the first reboot with the 9.0.x bootloader.
If you search the official los thread (don't remember if 17 or 16) you'll find some detaled postings on restoring the keys after updating the bl from 5.0.x to 9.0.x. The user, who has examined that has failed, but perhaps it helps to shine some light on your questions.
Getting Failed to clear BCB message: failed to open /dev/block/boot/device/by-name/misc: No such file or directory after phone crash
cant solve this please help
tried edl recovery flashed well but didnt solve problem
i have unlocked the bootloader and flashed many raw firmware didnt solved problem
flashed twrp sucessfully but cant mount storage intenal storage 0mb and cant swipe anything
get this message everytime in recovery
Getting Failed to clear BCB message: failed to open /dev/block/boot/device/by-name/misc: No such file or directory after phone crash
please help
I have no idea it helps, I had my phone crash on me and me trying my old-and-tried flashing etc. I did not have such BCB message, but it sounds like there is an issue with the partitions or partitioning.
There are nice YouTube videos at least that show how to flash the stock ROM (not giving link here for advertising etc).
it boils down to (FIRST get your data off the phone as you are going to lose this)
- TWRP being bootable
- in TWRP: factory reset, wipe data
- flash stock ROM twice: to partition A and after reboot to TWRP, to partition B. I do not know why this needs to be done, love to learn it by myself.
- flash without wiping a custom recovery if wanted.
- restore your data
