After @geiti94 and @ianmacd started the ball rolling for the Samsung Galaxy S10 series (Exynos 9820), it was really only a matter of time until we could do the same for the 2019 Galaxy Tab A 10.1 (Exynos 7904). The kernel source was released last May, allowing me to build a custom kernel with many of the problematic Knox security features disabled. What's posted below is a work in progress, but it should suffice to unblock efforts to build custom ROMs for this impressive tablet.

Notes:
  • The current process requires you to reset to factory defaults to remove file-based encryption. Remember to backup your data!
  • Custom kernels are specific to OEM releases, and rely on the latest posted kernel source (T510XXU5CUJ1).
  • This is unofficial and unsupported, so the usual caveats apply. Since we don't flash the bootloader, you should be able recover from any problems...but nothing is guaranteed.

Not working:
  • Support for file-based encryption

These images are not supplied pre-rooted with Magisk, since it's against the terms of use laid out by Magisk's developer, John Wu. To root the TWRP image yourself, simply use Magisk Manager to Select and Patch a File. More details on this process are available from @ianmacd's topic for the Galaxy S10 series here.

Hello All,

We just received a donation of about 300 Samsung SM-T515 tablets that were used in a national survey last year to use our a different survey. About 70 of these were locked by users with google ID, I have tried Factory Reset but got the message "Your phone was factory reset. Enter your PIN to unlock it." Unfortunately, we are not able to get these PINs, how can I bypass this? I have tried reloading the ROM with ODIN3 but am still getting back to the same screen. I can't unlock OEM as it requires login into the tablet first? Any help from here the great people here?

You can't bypass the FRP lock anymore. Your best bet is to contact Samsung tech support at 1-800-samsung

not sure what went wrong for me.. was on LOS 17 with twrp 3.4.0.0. Flashed the img file through TWRP then rebooted to recovery.

Though now bootlooping with the "Tablet Bootloader is unlocked and its software can't be verified - Press power button to continue"

That message was already coming up prior to the flash though that didnt stop LOS and TWRP from working perfectly before this flash..

Cant get to fastboot or any recovery.. (oh oh)..

Assume i need to wait till it runs out of power so i can get to Fastboot.. then ill do Odin OEM and start again..

right now i cant even turn it off..

To get out of bootlooping: Hold Vol+ and Vol- together, then connect USB to a computer and hold both keys until you are back into the download mode. There is a thread on here with a more detailed explanation.

Your problem is most likely due to the fact that the TWRP version you installed does not match the OEM kernel version. (This could be explained better in the OP). Solutions are:

1. Install an old TWRP version which matches your kernel version.
2. Update the kernel source by installing the newest OEM stock version first, then installing newest (and fitting) TWRP and your custom rom afterwards.

You sir are a gentleman and a scholar! Thank you.

Thx for you great work. Latest TWRP was installed on my Galaxy Tab A 10.1 (2019) by Odin. It starts but always in portrait mode instead of landscape mode. Any idea what went wrong?

My first rule 'have the stock files, so if I funked up something I can revert back and start from scratch'

So you need to flash the stock files and start again 🤔

I believe you can download the stock file from here.

I got the SM-T515 and it is running on android 11 with firmware T510XXU5CUJ1. The strange thing is that I have also the twrp-3.6.0_11-1. How can be possible? I can't remember haw I did it.... I bought another Tab A SM-T515, same firmware but I'm not more able to install the TWRP again. I'm goin crazy. Can somebody help please?
edit: I must correct myself. I tried again with different cable and I did it. Now is all okay.
Somewere I read that it is not possible to install TWRP on systems running Android 11 but I did it

I thought that at first when I got in this state with my SM-T510 during development, but it's really just a matter of getting the timing down. You need to hold the Power + Vol Down for exactly 7 seconds and then switch to Vol Up + Vol Down as it's restarting. Might take a few tries.

Too late. It's gone. Been looking for an excuse to drop the SM-T515 for a while now and you just gave it to me. A link to the device tree is still posted, though, if you want to give it a go yourself.
Magendanz is correct as it really just a matter of timing. Took three tries here on a SM-T515 that was stuck on the TWRP slash screen. I was able to get into the boot loader mode and flash the factory firmware using Odin. Thank you Magendanz.

    Hello.
    Source code of SM-T510 Android 10
    T510XXU3BTFN
    on https://opensource.samsung.com/uploadSearch
    ...and we just got a new drop of the AOSP 10 GSI. Please stand by...

    Just a quick update: Samsung posted the T515XXS3ASK5 source last night, so I expect T510XXS2ASK5 to follow soon. When that happens, I'll update TWRP for both the SM-T510 and SM-T515.

    As soon as kernel source is posted for T515XXS4ATE3, I'll post that too.

    New build posted for T510XXU5CUF4. Note that the bootloader in this OEM firmware release has rollback prevention, so you might want to give some thought first before upgrading.
