This is not Samsungs Android 10;). ATM for me Root didnt work, or better its not booting the root section - got only bootloop. But i dont have much more time to play around.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Roarmaster:
Right, if you want more info, also only magisk stable works. Beta or canary does not yet work.

After installing nexus, installing the multi-disabler script & then formatting the device is recommended. Then you can install magisk after booting into the rom first.

But yes, Samsung's Android 10 does look nice

Edit: you probably have to upgrade your Samsung firmware to Android 10 before doing all of the above

I followed the instruction on my SM-T510, but after flashing the TWRP via Odin the Tablet goes into the boot loop. When I get to TWRP all I can see is a number of random folders under sd_card root directory. The only fix is to go back to download mode and flash the official ATE3 firmware.

I have the bootloader unlocked, OEM is greyed out showing it is unlocked, USB debugging enabled but anytime I flash TWRP to AP with Odin I will lose the ROM! Any idea what could be wrong?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hanspampel:
If you followed the instructions, you would never see that kind of folders.

like it described in OP did the trick to decrypt your internal storage. But remember, all your stuff get lost. If you need multidisabler etc., use an external sd card.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] fmaher:
You are 100% right, I missed wipe DATA and had no idea how to install multidisabler as I had no way to mount the internal storage and copy the zip file. Many thanks for that.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
You missed the step to FORMAT data. Wiping data only erases PART of what is on the data partition and does NOT remove encryption.:( That is also why you need to move the zip files you will want to flash with TWPR to the external storage PRIOR to flashing TWRP. Otherwise you will need to remove the SD card from the tablet, use a PC to copy the zip files to it, and then remount it in the tablet.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hanspampel:
The only way to install root is via patching the twrp. SuperSU didnt work with newer devices. Its EOL, dont use it anymore. Use Magisk, not the zip cause its not working with SAR-devices cause there is no ramdisk in boot.img anymore. Use the search for how-to of patching twrp etc.

Or compile a kernel with build-in magisk yourself.

Trust me I did too. So I saw a link at notes on top of this page for stock. It will start you back at Newest Stock updated. click link follow till you find US and download. Depending on speed depends on how fast download is. Odin 3.14.4 is what I used. Use first three files only once you unzip. BL AP and CSC are the ones you will fill in. Read file names it will tell you where they go. And Basically going back to stock. Regroup as I am and when all esle fails you have this to go back to stock. Then regroup. I missed somewhere 2. Its been a long time since i have rooted anything so. Good Luck

Things have advanced a bit. Like an idiot, I flashed TWRP for SM-T515. Now I'm no longer stuck in a bootloop, but I'm stuck on the first boot screen (the one with the yellow exclamation mark). I tried flashing the stock rom and TWRP again and again, but nothing works. I am still stuck on the boot screen.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 4929york:
The link you posted is out of date. It is for the earlier version of stock. You have to flash one of the ROMs based on the BTFN version of stock. Either the Nexus ROM or the LOS 17.1. With either one, you have to flash it twice. After flashing the first time, you have to boot into TWRP and FORMAT the data partition. FORMAT not just Wipe, in order to get rid of the Samsung encryption. Then go back and flash to ROM again, to get the unencrypted data partition.

Hi Magendanz,

Please release the TWRP for Android 10. Samsung has release the source code of Android 10.

Thanks in advanced.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
If you search this thread, you'll find out that there's an incompatibility with the OEM system image that causes a boot loop. The latest TWRP image based on the Android 10 kernel works fine for custom ROMs, though, which is why I've included it with the latest Nexus Stock. That version would also work with AOSP or LineageOS GSIs.

If someone were willing to grab me a logcat for the boot sequence with TWRP and the OEM system, that would definitely help troubleshoot. I just haven't had a lot of spare bandwidth lately, and this task is pretty low on my To Do list.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] dunhill_:
Thank you for your effort.

I have tried this version of TWRP with stock firmware T515XXU4BTFK and got stuck at boot logo. So I think this version of TWRP has been built under Android 9 source code. Now I understand the problem.

I am ready to be a tester to fix this problem, but I do not know how to get logcat as you want when stucking at boot logo.

Please give me an indication to get the logcat

I have built twrp for T510 using Android 10 sources and my daughter's tab boots fine under latest Stock ROM.

I tried both twrp rooted booting and also stock boot.img rooted booting and it works fine. I used your Device tree, a self compiled custom kernel with BTFN sources and PIE TWRP sources and all good
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Well, that's strange, since that's exactly how I built the TWRP that's included in my Nexus Stock custom ROM. I will verify and then post my version based on the BTFN kernel source.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
So, here are the builds from early August that were made with the BTFN kernel source. If we're now convinced that this is working okay with stock OEM ROMs, I'll update this on the main page.

So, this latest release based on the T510XXU3BTH4 kernel seems to be working fine for me, but I have noticed that you've got to be very patient with OEM system images. It may look like it's hung on the SAMSUNG logo, but after about 5-10 minutes it will reboot and then proceed normally. I assume that Samsung is doing some kind of integrity check on the image, but that's just a guess.

Okay, that's decided it. I'm scrubbing this thread of any reference to the SM-T515. You'll need to find someone to build TWRP for that model who actually has hardware on hand for testing.

BTW, your device is not bricked. Just download the latest OEM firmware and flash with Odin to restore. Hold Power + Vol Down for 7 seconds to hard reset and then Vol Up & Vol Down (with USB cable connected) to enter Download mode.

Dont remove it, i can test it. I may have installed the wrong version.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
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.

You gotta do like you said, hold the two volume buttons while plugging in the cable. If there are no prompts to follow on screen you can load Odin on your PC right away and flash TWRP again or even go back to stock.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I think that old version of TWRP for SM-T515 still has the bug where it hangs on launch when it sees file-based encryption. You're just going to have to get the timing right on the hard reset to Download mode or wait for the battery to drain (which could take a week).

Change Log:

v3.5.0_9-0:

Updated to T510XXU3BTK1 posted kernel source.

Updated to TWRP 3.5.0 release built from android-9.0 branch.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
So, a new release was just posted that uses the T510XXU3BTK1 kernel, but for future reference:

While not true initially, the tarball (.tar.md5) version now includes just the recovery and vbmeta partitions. This is the bare minimum to allow you to boot to recovery and from there TWRP will allow you to do anything else you need, such as running multidisabler. You can even update TWRP form the .img file, since at that point you've already replaced the vbmeta partition to disable Android Verified Boot.

Since TWRP includes its own kernel, it can run independently from whatever kernel you've got in the boot partition. So, you should now be able to install TWRP over pretty much any OEM firmware release, newer or older.
