This is UNOFFICIAL TWRP for the Pixel C. That said, the TeamWin team greatly helped me in getting this working. But at the same time, neither TeamWin nor me take any responsibility whatsoever for any undesired outcome resulting from any kind of use of this project and project files! If you don't exactly know what you're doing then just walk away and do something good. Don't touch any options of which you don't exactly know what they're for!
What works:
* So far, everything; encryption support should work, but some feedback on this would be welcome
Problems:
* The GUI will be sometimes slow, sometimes super slow. This is probably due to the high screen resolution of the Pixel C.
How to install:
- Unlock bootloader
- In the bootloader, run "fastboot flash recovery <.img file>"
- Reboot into Pixel C bootloader
- Boot into recovery (or later on/from Android through "adb reboot recovery")
If the recovery doesn't stick after booting into Android:
- Do the install procedure as above
- Do NOT reboot into Android
- Press Vol-Down + Power until you see the bootloader menu
- Select "Boot into Android Recovery"
- When in TWRP, mount system
- Using TWRP's File Manager, or using adb, delete the file "/system/bin/install-recovery.sh"
- Reboot
After doing this, OTAs won't work any longer, but they wouldn't work anyway after installing TWRP. Just so you know

SHA1 hash: 3e97aae6cc18975683eda2bd3732faaecec14166
Changelog
:: 01-19-2016-1
- Removed screen timeout by default, since the GUI is very slow and the screen unlock slider is very hard to use
- Added an option to fix the Fastboot Full Cap flag directly from TWRP; you find the option in "Advanced". If the Pixel C should ever not let you flash in fastboot, boot into TWRP, select Advanced -> Fix Fastboot, swipe to confirm, and you're set.
:: 02-11-2016-1
- Rebased on twrp/android-6.0 branch (i.e. upgraded to TWRP 3.0.0-0)
The recovery is based on the Pixel C stock kernel.
Awesome! I can survive without root for the time being but being able to enable multiwindow would be amazing!
Thanks!
Edit: I am getting a FAILED (remote: unsupported command) error and cant flash this. Anyone know a work around?
Worked fine for me with "fastboot flash recovery [image name]" did you unlock your bootloader? Also root works just fine, you just have to boot from your PC.

I did unlock my bootloader but can't get anywhere. Tried updating my sdk, drivers everything. I guess I will have to keep playing with it.
Edit: I relocked my bootloader, and then unlocked it again and now it is working. If anyone else runs into this give it a try.
it successfully installed on my pixel c. is reachable as the Android Recovery option. and boots to bootloader to allow boot of boot.img
this is a good thing. thanks to all involved.
it's been 1 month since release and good way to celebrate.
Good work. Thanks you
hooray thanks! just to clarify: I need encryption disabled to use twrp or just to flash SuperSU?
I'm currently using phhusson's noverity boot-img to boot and with a modified vendor img root is working fine while encryption is enabled ... just having to boot via fastboot every time is a bit awkward. And since I don't know what happens if the device got stuck and reboots itselfe without the modfied boot it would be awesome to have at least a nandroid backup

Hey... You can use TWRP even with encryption enabled, you just can't write anything to /data.
However for the next build I'm going to enable TWRP's decryption option and see if it works with the Pixel C. If it does I'll post a new build this evening (European Time).
I tried the systemless SuperSU on a decrypted /data partition but it wouldn't work (bootloop), clearly there's a lot of ground to cover here, but like I said maybe the decryption functionality will help us here.
EDIT: I'm also working on a boot.img with disabled forced encryption. Looks like we're going to get proper root very soon.

What works:
* Well, basically everything IN TWRP works, it's just that without a kernel that disables forced encryption this is not of very much use. I tried flashing SuperSU, but it wouldn't work properly.
Problems:
* The GUI will be sometimes slow, sometimes super slow. This is apparently still a problem with how TWRP uses the graphics mode that is used on the Pixel C. Best is if you immediately disable the screen lock once you boot into TWRP because the unlock slider is abysmally sluggish.
How to install:
- Unlock bootloader
- In the bootloader, run "fastboot flash recovery <.img file>"
- Reboot into Pixel C coreboot bootloader
- Boot into recovery (or later on/from Android through "adb reboot recovery")

Hello thank you for this. Yesterday I tried to build as well twrp but it wasn't fully working.
I just imported this config with TW_INCLUDE_L_CRYPTO := true && TW_INCLUDE_CRYPTO := true
I didnt copy paste the twrp.fstab I added but added its path to BOAR_smthing.
Also I used omnirom's android-6.0 revision with dragon's device tree.
The recovery seems to boot, as
Code:
adb devices
returns XXXXXx recovery.
Also I can reach the device's shell with adb shell. Just the screen stays black.
I was wondering if I missed something. Is your device tree available online ?

Not yet. I'm going to upload it later on to the TWRP devs for official inclusion.
You need to merge the minui patch so TWRP can use DRM for video on the Pixel C; there is no fb0 device.
there were some new boot images out today. i flashed one of them. when i boot to recovery the sdcard is not able to be mounted. do you have any suggestions on what i need to do or look at in order to get it fixed?

Because /data is (force-)encrypted. I uploaded a new TWRP build with various fixes but decryption doesn't work.
What I also found out is that the boot image for the Pixel C is NOT an Android boot image (!), but a ChromeOS one. This puts a lot of things in doubt, for example I am not sure if systemless SuperSU can handle this.
But, I'm working on all that (working on boot img without forced encryption right now, but so far it doesn't want to boot completely)
OK, so, I'm running the device unencrypted now, but there are many issues still to resolve.
OK guys, if you really want actual SuperSU, and other root stuff, and decrypted /data, here's how it works but it's complicated and will only work tethered as far as I can tell.
First, download this boot image: dragon-boot-encryptable-01092016-1.img
Now here are the steps:
- make sure you have a stock boot.img handy in case something goes wrong (as usual I can not take responsibility but chances of bricking are extremely slim if you know what you're doing)
- boot into fastboot
- flash the above boot image to boot ("fastboot flash boot dragon-boot....")
- flash the TWRP recovery (latest version) ("fastboot flash recovery twrp-dragon-...")
- hold power+vol down pressed.. the device will turn off, keep it pressed even as it turns off, it will turn on again and you are in the coreboot menu
- select "Android Recovery" which will start TWRP
- in TWRP, select system as read only when it asks ("never write onto the system partition").. my boot image does not disable dm-verity which seems to be still in effect, so if you change /system, the Pixel will refuse to boot (even though it's unlocked... no idea)
- once in TWRP, go to "Wipe" and then choose at the bottom "Format Data" (just wiping will not work)
- when that's done stay in the recovery
- get SuperSU 2.66 from somewhere and flash it through TWRP (using sideload for example)
- when it's done, go to "Backup" in TWRP and only backup boot (the kernel) - no password - no compression
- somehow copy the backed up kernel from the device to your computer ("adb pull" for example), but in no case let the Pixel boot into Android
- when that's done, tell TWRP to boot back into the bootloader
Now get ready to be real quick...
- boot (just boot, not flash) the TWRP backed up boot image (it's 32MB large and called boot.emmc.win, but it's all good): "fastboot boot boot.emmc.win" (and now you have to be rather quick)
- It will boot up for a second and then go back to the "The OS will boot in 30 seconds screen"
- Again press power+vol down and hold it, even as the device turns off, until you're in the coreboot bootloader
- There, choose fastboot again
- And once again boot the boot.emmc.win image ("fastboot boot boot.emmc.win")
- Now let it boot up
- If everything went OK you should be in Android, with decrypted /data, and SuperSU should be installed and working
If you want to avoid being encrypted again (although SuperSU should survive that) you will have to boot tethered everytime using that boot.emmc.win image.
Known Issues: Somehow because /data is decrypted, "Security" settings in Android will crash. Hopefully you don't need anything in there. You might also want to skip setting a lock pattern or pin when doing the initial setup, it might crash too.
So far, I tried installing AdAway using root which worked just fine.
If someone figures out how make this untethered: you da real MVP!
Thank you sir!! I will report back if I encounter any undocumented issues.
OK so I've managed to install Xposed, was pretty straightforward except for the tethered boot. Still looking into making it untethered.
since your modified boot and no encryption it seems to be smoother in graphics. in any event, the thing worked in format of data and install of the supersu zip. so, well done.

So, followed these instructions and whenever I try to reboot into recovery I get the no command screen. Am I missing something? lol
Edit: So figured thats the stock recovery stuff. Got to the stock recovery but can't get into twrp
2nd Edit: I redownloaded the file and didnt rename it shorter this time and now it works...weird

Thank you for those informations .
Thank you so much for this! Aside from the laggy UI, which isn't an issue since we got TWRP (f yes!!!), this is amazing. Do you foresee any issues flashing fonts? I am not familiar with ChromeOS and Android structure combination as it seems there is a lot of talk about. Flashing a file that replaces the stock fonts with the ones of my choosing hypothetically should not pose a problem to /system/fonts/, correct? Thank you for your work
I just decided to move to CM12.1 on my Droid Turbo (XT1254) after the 1/27 Snapshot (YOG7DAO3J1) was posted. I am running this with TWRP 2.8.7.0, BHB27 Kernel, and OpenGAPPS 5.1. So far, almost everything has been fantastic and the performance of the device is like night and day compared to the Verizon software.
My problem is that the CM12.1 ROM has my device encrypted to begin with, which is nice but giving me trouble. I can't get into TWRP to install Xposed framework or other .zips via ADB. I have tried the following:
Disabling require password on startup
Changing the password in Android
Changing the password from root ADB shell
Using a pin
Trying "default_password"
Can anyone give me a solution or some advice? Any help is greatly appreciated!
Having same issue with TWRP not recognizing any decryption password given... Any ideas out there? Is TWRP incompatible with Droid Turbo HW Encryption, or ?

This thread is kinda old and I assumed nobody really knew what was going on with it either. I ended up just not using the encryption. The first time around mine was encrypted without me knowing, which was the issue. I just wiped all partitions and flashed the ROM again...
I am having a similar issue so i thought i would chime in, despite the older thread. I had a stock ROM that was encrypted and I was able to unlock and root with SunShine fine. Flashed on TWRP 2.8.7 and ran into a "Unable to mount storage. Failed to decrypt data" error. Updated to TWRP 3.0.0 and still have the same issue. Still working through a resolution as the phone is still functional if I just boot normally. When you mentioned you wiped all partitions, what process did you use? If i can just get access to the interal storage I can flash a ROM and be good to go.

So far, the only way I have been able to get encryption working with CM12.1 on the Droid Turbo is to do the folllowing (Note: This assumes you have bootloader unlocked and TWRP installed as your recovery):
Part 0: Make sure you have what you need
1. Stock Droid Turbo Firmware SU4TL for your device
2. The version of CyanogenMod 12.1 that you need. I recommend a Snapshot, but it's up to you.
3. TWRP 3.0.0 or later for your Droid Turbo.
Part 1: Final set up (Yes, we do this first)
1. Download CM12.1 & Download OpenGapps arm for 5.1
2. Wipe device (system, data, cache, internal storage), copy CM12 install zip and opengapps install zip via USB to device.
3. Flash CM12 and OpenGapps in TWRP
4. Set up device how you want it to be (install your apps, set up your accounts, etc).
5. Set whatever lock-screen PIN / Password / Pattern you are going to want on your phone in general!
6. Make a Nandroid backup of your 100% set up phone in TWRP
7. Copy your backup TWRP folder to your PC.
Part 2: Encrypt device and put everything back how we want it.
1. Flash stock Verizon firmware (SU4TL) via Fastboot. Do not flash stock Recovery, but put back TWRP if you did somehow (I use a simple bash script I have attached below).
2. Boot device, go through initial set up, don't download apps (we're going to be wiping the device soon).
3. Make sure your battery is 80%+ charged, and your device is plugged in.
4. Set a password or PIN on your phone.
5. Encrypt your device (this will be fairly fast, as /data is empty, but you should be asked for your encryption password on boot.)
6. Reboot to recovery. TWRP will ask you for your password to decrypt. It should work with no problem.
7. Copy your backed-up TWRP folder with your CM12 install to your device via USB. The TWRP folder goes in the Internal Storage root directory.
8. Still in TWRP (Do not reboot), go to Restore, and select the backup you just copied over. This will replace the stock rom with your CM12 backup.
9. Your CM12 install will be restored, but your device will remain Encrypted.
10. Reboot into CM12. Win.
You will need to decrypt your device every boot with the password that you selected when you initially encrypted your device. Your lock-screen password CAN BE DIFFERENT. That is why I do it this way. I have a fairly long password to decrypt my device on boot-up, but a pattern as my lock screen. That way I can quickly get into my phone during daily use without having to constantly type in a fairly complicated password.
My Mi5 was on MoKee rom (mashmallow), with encryption on(it seems to do the encryption the first time I boot MoKee rom, as I input a pin at the time). It seems to work fine: I had a PIN (call it P) set to unlock device. I need to input it every time I reboot device, and TWRP can also use it to decrypt data.
But it turns out I don't like Mokee and would like to use CM 13 instead. So today I booted into TWRP, wiped everything, and flash CM 13 stable build from 12202016. That goes well. First time boot CM 13, it ask me to set a PIN. I just used the same PIN (P). Now CM 13 boots fine. It will ask me PIN once on during boot process, and once more for first time unlock screen (from then on I can use fingerprint to unlock). Not sure why it need PIN twice, but at least I can live with it.
The problem is: now if I boot into TWRP, it will tell me 'PIN incorrect, failed to decrypt data. So I can only go into TWRP without access to data partition, which means it's useless. I have never set a different PIN other than 'P' on this device, so I'm not sure how I could progress with TWRP. I'm using lastest official TWRP for gemini (3.0.2-3). Anyone with more experience, please help. Many thanks.
--EDIT--:
Turns out I need to set "lock screen - input pin when booting" to 'On'. Then I only need to input PIN once during normal boot, and can use that PIN in TWRP to decrypt. It's not intuitive at all, but that solves the problem.
****ing TWRP, i wasted a lot of time on this fking bug
Same issue after new ROM installation
I own a Redmi Note 4 and had a pin (call it Q) that decrypted the data with no issues on startup as well as in TWRP decrypt. Now, recently I installed Resurrection Remix v7.0.0 Android Pie from v6.x.
Now whenever I try to open TWRP and decrypt with the pin Q, it says "decrypt failed" but it works whenever I reboot the device and it asks me to enter pin before startup.
I also could not find "Input PIN while reboot" in the settings, maybe due to new android version policy or because device is already encrypted.
Please help.
TWRP Version: 3.2.1-0
Log:
Updating partition details...
done...
Unable to mount storage
Full SELinux support is present.
Failed to decrypt data.
--EDIT--:
Just downloaded the latest TWRP (3.2.3-1) image from the official site, used "adb push <TWRP image> <location in device>", then "Install" and "Install Image" in recovery and it solved the issue. I used "/sideload" as device location to "adb push" because "/sdcard" wasn't mounted maybe due to encryption.

what are you trying to say on this part? sorry i am lost
Hello!
So recently I was able to install LineageOS 18.1 (GSI) + GApps on my Samsung Galaxy Tab A 8 (SM-T290) tablet and wanted to share how I did it. I noticed a lack of decent step-by-step guides to modding this tablet so I figure I'd share what I learned through scouring multiple threads and through multiple headaches. Fun fact: I also got this working with LineageOS 19 (GSI), however it ran pretty poorly and Android 12 is ugly as hell so why bother anyway? ALSO interestingly enough, you'll see I wrote [SM-T290N] in the title as well. That is the model of the Kid's Edition of this phone, which happens to be the one I had. So I can confirm this process works for the Kid's Edition of this tablet as well as the original.
Some Things To Note
Below I'll list the software/firmware I used in this process. You don't necessarily need to follow this exactly but I don't see any reason not to. The end result is a working install of LineageOS with GApps so if that's what you want I would just follow along step-by-step. ALSO I'm writing this from memory so if I make a mistake please let me know and I'll try and correct it.

What You'll Need
Your tablet
A USB Cable to connect your tablet to your PC
A 4GB+ MicroSD card
A Windows PC
Some patience
Instructions
Preparing Your MicroSD Card
1. Place the LineageOS 18.1 .img file from this thread (On SourceForge, there is a section below the files about the naming conventions and how they relate to the hardware of your device and configuration of your ROM. I used the lineage-18.1-20220315-UNOFFICIAL-arm64_bvS-vndklite.img.xz image for my device. If your device is slightly different, you can use Treble Info to determine what ROM you should use. Just make sure to use the VNDKLITE rom if your device supports it.
2. Place the multidisabler .zip folder on there as well. This will preserve encryption provided by TWRP after rebooting.
3. Finally, place the MindTheGapps .zip folder on your SD card (make sure to get the correct version. In my case this was the 11.00-arm64 version).
4. Insert your MicroSD card into your device.
Unlocking the Bootloader
So the first thing you're gonna want to do is unlock your OEM bootloader on your Samsung device.
1. Go to Settings->About Phone->Software Information and look for a field called "Build Number". Tap this Five Times until you see a notification saying developer settings were enabled.
2. Go to Settings->Developer Settings and look for the setting labeled OEM Unlock and turn it on.
If you don't see this setting try connecting to wifi, changing your date and time to around two months prior (I set mine to back to May 2021 since the firmware I was using was set in July 2021), then go back to your developer settings and switch them off and back on again. You should now see the OEM Unlock option.
Click to expand...
Click to collapse
3. From here, you can reboot your device into Recovery Mode by holding the Vol+ and Vol- buttons when the device begins to boot again.
4. You should see a blue screen with some options. Press the Vol+ button to enter Download Mode. This is where you'll use Odin to flash the firmware you need as well as TWRP.
Flashing Firmware
So when I attempted this process I used Magendanz's Unofficial TWRP 3.6.0 as it is the only version of TWRP I found for this device. I also used Odin v3.14.1_3B Patched from this XDA thread. Magendanz's TWRP requires you to have the T290XXU3CUG4 Firmware (I used the XAR region) in order to flash TWRP to your device (you can check wether or not you already have this firmware on your phone by looking the About Phone section again). It takes a while to download though make sure you have some time.
1. Download Odin and run the program. Unzip your firmware folder and use the relevant files when selecting the BL, AP, CP, CSC fields in Odin. I didn't use the HOME_CSC just leave it blank.
2. Connect your device via USB and Flash this firmware to your device.
3. Once your device restarts, go through the setup process and then repeat the Unlocking the Bootloader instructions above in order to make sure it is unlocked again.
4. Reboot your device the same way as stated above.
Flashing TWRP
Before starting, be aware that after you flash TWRP to your device, your device will restart and attempt to open the stock system again. You're going to want to hold the Power and Vol+ buttons simultaneously. You will likely get a warning screen saying that the bootloader is unlocked and may ask you to do a factory reset, this (I believe) is fine. The key here is that once you press the Power Button to continue (as instructed on the warning screen) you'll want to immediately press and hold the Power and Vol+ keys for around 6 Seconds before letting go again (you should be seeing the Samsung Galaxy Tab A logo screen). After letting go, wait around 3-4 seconds, if nothing changes, restart the device by holding all three buttons (Power, Vol+,Vol-) and attempt the process again. It's a pain in the ass but you'll get it eventually. Just make sure not to let the device boot into the system again as that can cause problems in TWRP and you'll likely have to start the process over (from flashing the firmware).
1. Once your tablet is once again in Download Mode, open Odin again and flash the TWRP (tar.md5 file) to the AP (recovery) partition. Do not use any of the other partitions.
2. If this is successful, your phone will begin to reboot. Quickly press and hold the combination of buttons Power and Vol+ until you see the warning dialog pop up. Once you do, release all buttons and be ready to quickly press and release the Power button continue, and then immediately after press and hold the Power and Vol+ buttons again for 6 seconds. After around 6 seconds, release all buttons. Wait around 3-4 seconds and, if the screen does not change to the TWRP logo, restart the device by pressing and holding all buttons simultaneously and try this step again.
3. If you have entered into TWRP, congrats!
Installing Custom ROM + Software in TWRP
1. The first thing you'll want to do is select the Wipe->Format Data. Type 'yes' and hit enter (or swipe I forget which).
2. Next, select Install, and then select your MicroSD card as your storage device. You should see your zip files (if not switch from the install image option).
3. Install the multidisabler, do not reboot
4. Go back into Install and select Install Image (might not be the exact naming) option. Select your MicroSD card as the storage device again and install the LineageOS 18.1 rom. Do not reboot.
5. Go back into Install and select your MindTheGapps zip file and install it.
Now, a lot of people run into a problem when trying to install Gapps which is your device complaining about no more available space in the system partition. If this is the case, go back to Wipe and select Advanced Wipe. Select your system partition and then select Change or Repair Partition. Once you're here you should see the size and available space of your partition. You'll want to hit Resize Partition and let it do it's thing. To confirm it worked, go back to Wipe->Advanced Wipe->Select System->Change or Repair Partition and your available space should be much larger now. Now just attempt to install MindTheGapps again.
Click to expand...

Final Steps
Once you reboot you should be able to successfully reach the setup screen for Lineage. Go through the steps of setting up your device as usual and be sure that Gapps are installed. Go ahead and re-enable developer settings and enable USB-Debugging and Root Debugging. The reason for this is that, when I first installed Gapps, Google Play Protect would keep throwing warnings at me about my device not being Google Play Certified. This means I couldn't actually use any of the google play services. If you run into the same issue, here are the steps you can take to fix it:
1. First, go into Settings->Apps and find your Google Play Services app. Clear the cache and delete the app data, then reboot your device. If you try and sign into the Google Play store and you are able to without getting any play protect warnings, then you're good you can disregard the following steps.
2. If you are still receiving these warnings, you'll want to head over to this site and follow the instructions (I'm not gonna tell you how to use ADB here). Once you submit your framework ID, reboot your device. Everything should be working fine now.
And that's it! If I am forgetting any steps please let me know, again I am writing this from memory of the process so it may be missing some minor details. I hope this helps!!!
How's the stability, speed and the responsiveness on Lineage with a t290? I have mine rooted debloated and twrp installed but it is slow on stock OS

It runs surprisingly well! Much better than stock. There’s virtually no input lag and the battery life is also very solid on lineage.
Where i run into some lag is when trying to use apps that have embedded video in them. For whatever reason the T290 cannot handle video very well at all.
So yeah I would definitely recommend trying it, it’ll really breathe new life into that tablet

Glad it worked out for you! Let me know if you have any more questions and I'd be happy to help.
Hi! is this applicable also for SM-T295?
for those trying to figure out the Google Play Certified page with the adb command
Code:
adb shell 'sqlite3 /data/data/com.google.android.gsf/databases/gservices.db \
"select * from main where name = \"android_id\";"'
do : adb shell
first then paste in :
sqlite3 /data/data/com.google.android.gsf/databases/gservices.db \
"select * from main where name = \"android_id\";"
and it shouldn't give you the error
i must say. linageos on my sm-t290 is really nice
its fast and smooth way much better then stock fw
i would reccomend anyone with a t290/t295 to install this GSI
Im into a bootloop right now after a few fails with installing Lineage on my SM-T290..
Seems like i cant install any rom? not sure how to fix this issue, can anyone point me in the right direction?
Im able to get into TWRP and download mode. but cant install any rom?

Hello!
So recently I was able to install LineageOS 18.1 (GSI) + GApps on my Samsung Galaxy Tab A 8 (SM-T290) tablet and wanted to share how I did it. I noticed a lack of decent step-by-step guides to modding this tablet so I figure I'd share what I learned through scouring multiple threads and through multiple headaches. Fun fact: I also got this working with LineageOS 19 (GSI), however it ran pretty poorly and Android 12 is ugly as hell so why bother anyway? ALSO interestingly enough, you'll see I wrote [SM-T290N] in the title as well. That is the model of the Kid's Edition of this phone, which happens to be the one I had. So I can confirm this process works for the Kid's Edition of this tablet as well as the original.
What You'll Need
Your tablet
A USB Cable to connect your tablet to your PC
A 4GB+ MicroSD card
A Windows PC
Some patience
Instructions
Preparing Your MicroSD Card
1. Place the LineageOS 18.1 .img file from this thread (On SourceForge, there is a section below the files about the naming conventions and how they relate to the hardware of your device and configuration of your ROM. I used the lineage-18.1-20220315-UNOFFICIAL-arm64_bvS-vndklite.img.xz image for my device. If your device is slightly different, you can use Treble Info to determine what ROM you should use. Just make sure to use the VNDKLITE rom if your device supports it.
2. Place the multidisabler .zip folder on there as well. This will preserve encryption provided by TWRP after rebooting.
3. Finally, place the MindTheGapps .zip folder on your SD card (make sure to get the correct version. In my case this was the 11.00-arm64 version).
4. Insert your MicroSD card into your device.
Unlocking the Bootloader
So the first thing you're gonna want to do is unlock your OEM bootloader on your Samsung device.
1. Go to Settings->About Phone->Software Information and look for a field called "Build Number". Tap this Five Times until you see a notification saying developer settings were enabled.
2. Go to Settings->Developer Settings and look for the setting labeled OEM Unlock and turn it on.
3. From here, you can reboot your device into Recovery Mode by holding the Vol+ and Vol- buttons when the device begins to boot again.
4. You should see a blue screen with some options. Press the Vol+ button to enter Download Mode. This is where you'll use Odin to flash the firmware you need as well as TWRP.
Flashing Firmware
So when I attempted this process I used Magendanz's Unofficial TWRP 3.6.0 as it is the only version of TWRP I found for this device. I also used Odin v3.14.1_3B Patched from this XDA thread. Magendanz's TWRP requires you to have the T290XXU3CUG4 Firmware (I used the XAR region) in order to flash TWRP to your device (you can check wether or not you already have this firmware on your phone by looking the About Phone section again). It takes a while to download though make sure you have some time.
1. Download Odin and run the program. Unzip your firmware folder and use the relevant files when selecting the BL, AP, CP, CSC fields in Odin. I didn't use the HOME_CSC just leave it blank.
2. Connect your device via USB and Flash this firmware to your device.
3. Once your device restarts, go through the setup process and then repeat the Unlocking the Bootloader instructions above in order to make sure it is unlocked again.
4. Reboot your device the same way as stated above.
Flashing TWRP
Before starting, be aware that after you flash TWRP to your device, your device will restart and attempt to open the stock system again. You're going to want to hold the Power and Vol+ buttons simultaneously. You will likely get a warning screen saying that the bootloader is unlocked and may ask you to do a factory reset, this (I believe) is fine. The key here is that once you press the Power Button to continue (as instructed on the warning screen) you'll want to immediately press and hold the Power and Vol+ keys for around 6 Seconds before letting go again (you should be seeing the Samsung Galaxy Tab A logo screen). After letting go, wait around 3-4 seconds, if nothing changes, restart the device by holding all three buttons (Power, Vol+,Vol-) and attempt the process again. It's a pain in the ass but you'll get it eventually. Just make sure not to let the device boot into the system again as that can cause problems in TWRP and you'll likely have to start the process over (from flashing the firmware).
1. Once your tablet is once again in Download Mode, open Odin again and flash the TWRP (tar.md5 file) to the AP (recovery) partition. Do not use any of the other partitions.
2. If this is successful, your phone will begin to reboot. Quickly press and hold the combination of buttons Power and Vol+ until you see the warning dialog pop up. Once you do, release all buttons and be ready to quickly press and release the Power button continue, and then immediately after press and hold the Power and Vol+ buttons again for 6 seconds. After around 6 seconds, release all buttons. Wait around 3-4 seconds and, if the screen does not change to the TWRP logo, restart the device by pressing and holding all buttons simultaneously and try this step again.
3. If you have entered into TWRP, congrats!
Installing Custom ROM + Software in TWRP
1. The first thing you'll want to do is select the Wipe->Format Data. Type 'yes' and hit enter (or swipe I forget which).
2. Next, select Install, and then select your MicroSD card as your storage device. You should see your zip files (if not switch from the install image option).
3. Install the multidisabler, do not reboot
4. Go back into Install and select Install Image (might not be the exact naming) option. Select your MicroSD card as the storage device again and install the LineageOS 18.1 rom. Do not reboot.
5. Go back into Install and select your MindTheGapps zip file and install it.
Final Steps
Once you reboot you should be able to successfully reach the setup screen for Lineage. Go through the steps of setting up your device as usual and be sure that Gapps are installed. Go ahead and re-enable developer settings and enable USB-Debugging and Root Debugging. The reason for this is that, when I first installed Gapps, Google Play Protect would keep throwing warnings at me about my device not being Google Play Certified. This means I couldn't actually use any of the google play services. If you run into the same issue, here are the steps you can take to fix it:
1. First, go into Settings->Apps and find your Google Play Services app. Clear the cache and delete the app data, then reboot your device. If you try and sign into the Google Play store and you are able to without getting any play protect warnings, then you're good you can disregard the following steps.
2. If you are still receiving these warnings, you'll want to head over to this site and follow the instructions (I'm not gonna tell you how to use ADB here). Once you submit your framework ID, reboot your device. Everything should be working fine now.
And that's it! If I am forgetting any steps please let me know, again I am writing this from memory of the process so it may be missing some minor details. I hope this helps!!!

bro, I have a problem, my tablet is in a bootloop and I don't know what to do, try with other custom roms but it's the same, what do I have to do so that when I install a custom room it doesn't give me that error?
Flashing the Gapps package resulted in an error: Failure to mount '/system_root' (Invalid argument)

Sorry for the bother, new to Android modding scene.
I went into the recovery menu (oem unlock on) and tried to flash TWRP as written on this guide, but I get a secure check fail : aboot on my device and fail on Odin. What do I do here?
Edit: Aparently my device is SM-T295, basically the LTE version of the same device, which is why it isn't recognising it. My bad.
Do you have any video to teach better ???

Shouldn't matter, TWRP is the same for both variants.
There's two ways to get around the secure check fail problem:
After updating via Odin, make sure you immediately interrupt the boot and force reboot into Download Mode. Then, flash TWRP.
Or, after updating, allow your device to boot to Android, skip through the setup wizard (make sure you connect to the internet), and enable Developer Options. Ensure OEM Unlocking is there and grayed out. If not, leave it for a bit until it is. This disables Vaultkeeper on the bootloader. Then, reboot to download mode and flash TWRP.
In both cases, after flashing TWRP, DO NOT let the device boot into Android. Force boot into recovery, then install the Multidisabler from here.
Now to my own problem...
I don't know what I did differently (or wrong) but I cannot get LineageOS to boot correctly on my T290. I was running 18.1 before. I recently updated to CVG3 and followed the same process as I did before - flashed TWRP, then installed the LineageOS GSI to /system.
18.1 continuously bootloops without even loading LineageOS.
19.1 gets to the LineageOS splash screen, and occasionally the setup screen, but continuously reboots also.
After flashing TWRP, I'm installing the multidisabler, then wiping /system, /data, /cache.
Any idea what I'm doing wrong?
@J.Michael any thoughts? You're more familiar with Samsung than I am

I think I have a solution.
I see that you are installing the multidisabler after you booted TWRP and by wiping the partitions, however, what you are supposed to do is this:
After you have booted into TWRP and have swiped to allow modifications, go to Wipe> Format Data and type yes. Don't reboot, and don't wipe any other partitions.
After that, go to install and then install the multidisabler, don't reboot.
Then install the latest LineageOS gsi to the system partition, and finally install gapps, then reboot.
Make sure you are choosing the arm64_bvS_vndklite variant, otherwise it will bootloop.
Hope this helps!

Okay, so install Multidisabler AFTER wiping data. I'll try that.
I'm using the bgS image so it's already got Google apps. I didn't have any success flashing any of the Gapps packages on the vanilla images.
Is Multidisabler still necessary on Android 11 on this device, or do we just need a patched vbmeta.img?

Yes, Multidisabler is necessary, otherwise it'll bootloop. I haven't tried anything with a patched vbmeta and frankly don't want to.
The bgS version will work just fine for Android 11.
Currently running Android 13 with LineageOS 20.0, the bvS version. Gotta say it works great. MindtheGapps 13 will work, I haven't encountered any "This device is not certified" issues.

Do I need to wipe /system or /boot or anything before installing? I did exactly as you said - rebooted to recovery (was running Samsung stock), formatted data, installed multidisabler, then installed a LineageOS 19 image to /system. It begins to boot (LineageOS animation) then reboots.
Are you using Andy Yan's builds?

Nope, you don't have to wipe any other partitions, only format data
Yes, I'm using Andy Yan's builds. I'll link the thread here: https://forum.xda-developers.com/t/gsi-13-lineageos-20-trebledroid-based.4517345/
If I may ask, which type GSI from Andy Yan did you use?

Flashing the vndklite one now to see if it works
If I can get this working, I plan on using a bgN flavor so I can just install Magisk, since I don't use SuperSU
Edit: vndklite is bootlooping too
