I assume this one will work: https://samfrew.com/download/Galaxy__Tab__A__-2019-__/lu35/XAR/T510XXU2ASK5/T510OXM2ASK5/

I did install two software updates on the tablet. Sorry for asking but where are the precise instructions? OP didn't include them.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] riverstyxxx:
I keep hitting a brick wall at every corner I turn. Won't even let me sideload the official firmware. Pictures attached, please help.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] riverstyxxx:
Got it working. Not sure how though. I did reinstall the latest firmware with odin, that probably fixed it.

TWRP

I have unlocked OEM in developers option, checked USB debugging then when I restart and go to downloading it says volume up to continue long press volume up to unlock bootloader or volume down to cancel. Then when i go into Odin and but twrp-3.3.1-6-T510XXU2ASK5-20200215.tar.md5 in AP and hit start it either does nothing or fails am I doing something wrong?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
You stated the three options but don't say which one you chose. You need to choose the long press option to unlock the bootloader. This will also cause the tablet to perform a factory reset. At that point, you need to let it boot, enable wifi but skip the rest of the setup process. Then you need to enable developer mode again. Only at that point can you go back to download and flash TWRP.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rynbdr:
Thanks I just got it to go through but thank you for your quick response.

Thank you for everything works awesome even got it rooted easily
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I've only rooted by flashing a custom ROM and then rooted via Magisk. If you intend to keep the stock ROM, there is a step by step tutorial for doing it but I can't help with that.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Skyfire1:
Which one, any recommendations for custom rom ? Thanks :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I'm using the Nexus 10 right now but part of the fun of TWRP is that you can try a ROM and make a backup and then try another. I've had as many a six different ROMs stored on one of my tablets.:good:
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I just released a TWRP build for the T510XXS3ATB4 kernel, which just had its source posted by Samsung today.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 0KimT1:
Rn I'm rooted via magisk and on the december 2019 patch.

Would it be possible to update to the march 2020 ota update without losing anything by flashing BL,AP and CSC_HOME in odin?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 3c:
I just did this on a S10+, worked like a charm. However on the Tab A I remember I had to use a beta version of magisk from a different repo, which I assume is now part of official build, but might be worth checking.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] avalx:
I did this successfully, but if you want to keep root I believe you have to patch the AP tar file before flashing!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 0KimT1:
Please excuse my lack of knowledge, but how should I go about patching the AP tar file?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 3c:
That was IMO implicit, but I suppose it is not clear to everyone.

Put the AP file on your device, open it with magisk (install, from file, etc...), then copy back the magisk_patched.tar found in download folder back to your PC. That's your new AP file, rooted.

Make sure to patch all files: BP, AP (the tar file), CP and HOME_CSC.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] avalx:
I followed this instructions: https://topjohnwu.github.io/Magisk/install.html#magisk-in-recovery

BTW, how did you root the first time? I used the same instructions everytime.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 0KimT1:
wth i just read through the link u sent and i've never patched any of the AP/BL/CSC files using magisk manager.

I unlock the bootloader, flash twrp, format data (because the files are all encrypted), flash multidisabler without restarting, format data again, restart to system (don't know if this is necessary), boot to TWRP, install the magisk zip file et voila.

Is there something I'm missing? Or am I doing it wrong? because magisk works completely fine on my SM-T510.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] avalx:
Well then, I guess you can try the same again - without formatting data, but I don't know if this will work. I don't have TWRP installed (yet), so I do as per instructions from the link.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 0KimT1:
I just realised that I don't actually care about staying rooted after updating, as I can simply reflash magisk through TWRP and that doesn't require me to wipe any data.

My main goal is to not have to wipe anything whatsoever, so I don't have to reinstall all my apps and relogin on everything.

So having said that, If I flashed the unmodified stock AP,BL and HOME_CSC files from the march update zip I downloaded off samfirm, then would the only issue be that I lose root?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] avalx:
Probably, but I can't say for sure, maybe somebody more knowledgeable will confirm that.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 0KimT1:
Soo i tried flashing the stock tar.md5 files and everything seemed to be going well except when the tab booted up, it went straight to some OS recovery saying my data could be corrupt so i ended up having to wipe everything ?

i uninstalled magisk before flashing the new update so i don't know why it went wrong

does this mean i'll end up having to wipe everytime i update?

Result of TWRP installation with Odin

I tried to apply the ones presented by Magendanz in the original tutorial. I follow all the instructions to install TWRP on Samsung Galaxy Tab A10.1 SM-T515 (2019). The process seemed to start well, but after staying 5 minutes in Figure 1, the answer was FAIL! (succeed 0 / failed 1), as shown in Figure 2. Why doesn't it work for me? Where am I wrong? I Mention that I tried several times and had the same result.

I'm sorry but I don't know how to insert images from my computer.

Samsung Galaxy Tab A10.1

I managed to install ROM-T515XXS4ATB4-20200319112130 and everything went very well. I even did it twice to check myself. After that I tried to install TWRP, but I got an error. Probably not a version for my tablet. My tablet is T515XXS4ATB4. Do all the characters in this code have to match exactly? There is a custom TWRP version for it?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hanspampel:
Read and understand what youve read.;) Actually there is no twrp for atb4 for t515 (=lte device), only for wifi version (t510). [MENTION=903232]Magendanz[/MENTION] have to compile it. Sources are up;). [MENTION=8493577]papagalus[/MENTION]

You have to wait for fresh version.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yeah, the sources finally went up

yesterday

. The first one Samsung posted for ATB4 was for the wrong device.

I've built the custom kernel and TRWP, and just need to package together the tarball. Give me an hour or two.

UPDATE: New builds for T515XXS4ATB4 are now posted. The usual caveats apply, since I don't have the hardware to test these.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] papagalus:
I tried to install it and ... FAIL!

I have complied with all the requirements of the tutorial and still do not succeed.

Used two Odin variants: 3.14.1 and 3.14.4 and with both I got the same result.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Okay, I think it may be time to drop support for the SM-T515 entirely. It just isn't practical to build it blind, without any hardware for testing.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] papagalus:
I'm very sad that you make such a decision. For us, the many and inexperienced, you were a reliable help. I thank you for your work.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Yes, it is sad. But it was also inevitable. There just aren't many people who try to combine a smartphone with a tablet. That means that those who do have what are known as "orphans". It is just too difficult to dev when you don't own the hardware and it is rare to find a dev who does own an "orphan".

I know there are people with poor eyesight who prefer a tablet because of the larger screen, but there are other ways of accomplishing that. (Right now I have a 10" T720 acting as a phone, but it is doing via wifi with MagicJack.) But if you insist on buying a phablet, you can't expect the support you'd get with a tablet.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] klock:
I got TWRP installed but now it just gets stuck at the splash screen. Waited 15 minutes. Holding power button doesn't do anything so I hold the power and volume down until it resets, but it goes back into TWRP and gets stuck again. Is there anything I can do?

Edit: Looks like I got an older version by recommendation of some website. I should be able to wait until the battery has died, give it some charge, then go into download mode again, right? Because right now I can't escape booting into TWRP and can't use ADB.

Edit 2: Nope. As soon as I plugged it in it tried to boot up and went back to the TWRP splash image. Is this device done for?

Edit 3: Saved. From a dead battery, I could enter download mode by holding both volume buttons and plugging in, and then use Odin to reapply the correct version of TWRP from here. Whew!

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ASHLEY117:

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ASHLEY117:

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
That's excellent news! Yes, I'll keep up the T515 builds of TWRP as long as we don't hit a difficult issue to troubleshoot. I'd appreciate you doing regular smoke testing when they're posted, since I can't do that myself.

Hi there,

i already succeeded flashing twrp on my t510 with atb4 firmware. Now I want to repeat it and could not manage it anymore. The flashing of TWRP stuck at about 80% and doesnt finish.

I did the following:

- Flash of ATB4 (BL, AP, CSC) with Odin 3.13.3

- Boot and enable USB debugging (is this necessary?)

- Flash TWRP => Stuck!

Do I miss something? It is weird because I already managed it some days ago and could not repeat...

Just for info: If somebody needs root:

Rooted with TWRP and ATB4 the following way:

Install TWRP

Install Multidisabler 2.3 (general type)

Format Data

Boot to system

Configure (developer options, etc...)

Boot to TWRP

Install Magisk 20.4.zip (regular version, no canary)

Format Data

Boot to System

=> Root and TWRP

Question:

I already rootet my A40 mobile the same way. Why is it necessary to patch the AP-File from orignal stock rom? I never did.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] pheraspu:
I did this with T515XXS4ATE3:

ODIN AP:

Flash TWRP.tar

twrp-3.3.1-7-T515XXS4ATB4-20200420.tar.md5

TWRP RECOVERY:

Flash multidisabler-t51x-1.41.zip

Wipe DATA (format)

BOOT TO Recovery

Flash MAGISK

RESTORE DATA (from your previous backup if you had TWRP installed)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ruffyrisco:
Multidisabler 1.41 didnt work for me... :confused: I used the newer version of the standard multisdisabler.

You booted directly into recovery again and installed magisk? I did the long way with complete system setup. Directly booting into recovery would speed everything up! :good:

With my A40 I could flash magisk directly after multidisabler. But here it didnt work...

Hello I have a problem my galaxy tab will try to boot into trwp recovery but it's stuck on the picture screen, I can't get it into download mode again. As soon as the Samsung logo appears there is a yellowbox with a.!

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
That older version of TWRP will hang on the splash screen if the user partition is encrypted. You need to update TWRP or format the user partition, which you could potentially do via adb shell. (Even from a hung splash screen, I was often able to connect via adb shell.)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Doodlebob1:
Any links to get all the files or a guide on how to do it ? i dont hear any connections sound to my computer if i plug it it its not being recognised at al
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yeah, I think that first release didn't even connect via ADB when it hung on the splash screen. You'll probably need to flash the OEM firmware and start all over, this time with the latest TWRP release.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Doodlebob1:
i would do that but i cant get it into downloadmode so i can start over it keeps restarting and when it starts it goes straight to the twrp recovery right after the warning screen , vol up and vol down doesnt help because it keeps turning on i cant get it to turn off and it wont go to download mode
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Plug in the USB cable, press and hold Power and Volume Down for 7 seconds until the screen goes black and then immediately switch to Volume Up & Volume Down. This should get you to Download mode.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Doodlebob1:
wow i am trying this the past to 2days to get it into download mode but that worked thanks do i have to reflash everything or just the trpw?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Actually, flashing the latest TWRP should do it if you haven't triggered VaultKeeper. No need to revert to signed OEM firmware.

I've always found that the OEM Unlocking option reappears after flashing the stock OEM firmware. There are also other little tricks that you can play with the date to work around the VaultKeeper timer. A quick search of the Galaxy S10 forum should reveal them.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] redexit:
Thank you. My understanding is that there was a trick to get around the 7 days of wait time by changing the date and time or downgrading the OS, but after the update in last January or December and with the newer devices, there is no other way but to actually wait. I am really hoping that I am wrong in this, since this is truly annoying. EDIT: I did search to find any updated methods, but so far I haven't successful.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Yes, I don't believe the kernels in recovery and boot have to match, so running a newer one in TWRP should be fine.

I would be cautious about installing a newer version of NoKnox on stock T510XXU1ASC7, though, as then you're mismatching vendor and system partitions. Those versions need to match.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] themontyhouse:

After 7 days, I was able to successfully install TWRP, NoKnox and Magisk. Thank you very much! The question that I have now is that somehow I am not able to encrypt the device. It starts encrypting and after a few minutes, it just reboots and the device is still not encrypted. Is this because of the NoKnox that I installed? If so, do I have any option to encrypt the device (and still be able to use TWRP)? Thank you.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
Perhaps. There are two settings that we might try reverting in the custom kernel that could have affected this.

CONFIG_ENCRYPTED_KEYS=y
CONFIG_SECURITYFS=y

Frankly, I wasn't sure what these did, but was just following the lead from another Tab A Samsung custom ROM dev that had them disabled. Since [MENTION=991723]ianmcd[/MENTION] didn't change them for the Galaxy S10, I'll try rolling it back on the next release.

Frankly, my bigger priority right now is to get it so that TWRP doesn't hang on an encrypted userdata partition. That's proving to be a major PITA.
