First of all: Thanks to this thread, I was able to gain new "Galaxy" knowledge. A special thank you goes to @Magendanz and @mingkee, whose contributions enabled me to install various CustomROMs on the Galaxy Tab A 10.1 [SM-T510] [ gta3xlwifi ].

Completely new to me, although already known to you for two years, was Samsung's process "unlock bootloader". On my Galaxy S9+ [SM-G965F], the "OEM unlock" is sufficient to install a custom Eecovery and ROM.

The Odin error message "RQT_CLOSE !!!" [T510 with Stock Android 11.0] was unknown to me until then. The net is full of tips on "RQT_CLOSE !!!" - but none led to success. It wasn't until I read and applied @Magendanz's posting #8 and @mingkee posting #19 that I was able to overcome this previously unknown Samsung hurdle of "unlocking the bootloader".

First @Magendanz's TWRP 3.5.2 release built and [ROM][SM-T510][UNOFFICIAL] LineageOS 17.1 for Galaxy Tab A 10.1 (2019) was tried, release LineageOS 17.1 build 20200713.

In the course of further testing, this was followed by RobotHanzo's OrangeFox Recovery R11.0 [gta3xlwifi] with GSI ROMs /e/ by e.foundation IMG-e-0.17-q-20210529117214-dev-treble_a64_bvN and Andy Yan's personal builds // GSI lineage-18.1-20210713-UNOFFICIAL-treble_a64_bvS [ ARM 32-bit with 64-bit binder ], supplemented with root Magisk 23.0, Minimal microG v2.10 NoGoolag Edition, MinMicroG Aurora Services along with NanoDroid F-Droid 23.1.2.20210117 Stable Realease.

Both GSI ROMs are still buggy, for example they don't support microSD cards, although OrangeFox Recovery R11.0 as well as TWRP Recovery do, or they reboot when I change the purpose for USB connection to PTP or file transfer.

Knowing the disadvantages compared to a device-specific CustomROM, however, I'm very happy for the time being to have largely banned the 'Samsungs' and 'Googles'. Many thanks to everyone who has made a constructive contribution here.

Can you please update this to T510XXU5CUF4
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Just installed this with opengapps pico. During setup it didn't ask to restore from the cloud. Did a factory reset to try it again thinking I missed a step, but it did the same thing.

edit: Notifications had a box to finish setup and it restored apps. But after doing so, I decided to factory reset again and re-install only the apps I wanted. The backup was from the Nexus ROM and the purpose of trying this ROM was to use the Pico gapps. Restoring from the Nexus backup just put all of the unwanted stuff back.

you could install CaOS without Gapps (caos-*-a64-bvZ.img.xz) or a other GSI based ROM

CaOS:

Hello friends!

I've been using this ROM happily & successfully for years.

I see a newer TWRP is out & a newer LineageOS 18.1

Can I upgrade my TWRP with Flashify after rooting TWRP with Magisk.

Then either wipe or dirty install 18.1?

I do have the SM-T510 I just wanted to keep my chatter here since this is the ROM I'm currently on & there are so many variants the threads & sections are kind of a mess I don't want to end up getting myself into a non working state.

Would appreciate any & all advice on upgrading from this exactly ROM to newer TWRP & newer ROMs.

Thanks very much & Happy NYE! or 2022 to those already there.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rw_on_xda:
may I ask where did you see that ?

Andy Yan's ?

if yes: then he is on 19 already

"same s-h-i-t, different year (only)" :p
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] metalfreak2006:
hello I would also be interested in lineos18 or 19th but somehow neither of them works for me. i saw it on "andy's" site too
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaladhjin:
I'm not actually sure I apologize I am a bit confused there being so many variants.

Ahh I see it here in related threads.. on no I am mistaken that is 16.

I'm basically looking to update my tablet from August 08 2020 of this ROM to either the newest of this ROM or perhaps try another.

Do you have an opinion on which you like best for SM-T510?

What do you mean about Any Yan 19. Is there a Lineage OS 19 for the SM-T510?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rw_on_xda:
then you need to bring the last stock on your device first.

go through OEM and bootloader unlock.

install nexus

it depends on your needs.

if you need google apps, go for nexus

if you don't want Google apps at all, go for another rom, e.g. CAOS (the variant without google)

AFAIK, Andy Yan has build a LOS 19:

it here:

https://xdaforums.com/t/gsi-12-lineageos-19-x-gsi-a64b-64b.4358041/page-2

I currently don't know how it plays...

@Magendanz LOS is 17.1 (only)

be aware:

if you have flashed lastest stock, you can't install @Magendanz LOS 17.1 any more

cause

boot loader version in last stock is 5

boot loader version in @Magendanz LOS needs version 4

you can't downgrade from 5 to 4 !!!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Krekle:
Does this mean you can`t install this from a tablet with Android 11?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
You could just install my latest TWRP (or Nexus Stock) and then flash Andy Yan's LineageOS GSI (arm64_bvS) to the system partition from there.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaladhjin:
So I've upgraded to the latest version of this ROM successfully but notice Magisk no longer says installed but the Magisk app is still on the tablet.

I updated TWRP but could not find a flashable zip of Magisk to flash so I'm curious.

I went through this process & patched the TWRP file so I really flash the patched img file to recovery?

There is no flashing a Magisk.zip anymore?

From existing TWRP install: (No need for data wipe.)

Hold Power & Vol Up during restart to enter TWRP recovery

Tap Install->Install Image, select your image (.img) file, pick Recovery partition, and then swipe to install

Reboot to system

What about rooting with Magisk?

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.

I looked for info here too but am not sure if I should be flashing the patched twrp img to boot or recovery. 🤔

Installation

The Magic Mask for Android

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaladhjin:
Wuh oh.. looks like I'm in trouble.. I made an error somewhere.

I flashed the latest version of this ROM & flashed an updated TWRP from here: https://xdaforums.com/t/recovery-unofficial-twrp-3-6-0-for-2019-galaxy-tab-a-10-1-sm-t510.3934805/

The ROM booted fine from there but Magisk wasn't installed.

So I found out how to patch the twrp image & I did.

I was going to reboot back into TWRP to flash the patched image to recovery hoping I was right about that & I can't get back into TWRP the device is boot looping.

I'm not sure what to do now :-/

I can't even get it to power off I hold the power button & it isn't turning completely off.

I'm pressing Power & Volume Up hoping to get into Recovery.l

Also holding Volume Up & Down to see if I can get into Download Mode.

It just keeps boot looping I can't get into TWRP or Download Mode it seems.

S.O.S.!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rw_on_xda:
if you're on the lastest stock you have 5CUJ1

@Magendanz LOS is based on 4BUA

so if you would try to flash @Magendanz LOS on the lastest stock a downgrade of the bootloader (more ?) from 5 to 4 would be involved.

and that's is *not* doable, cause a downgrade is denied, the flash will fail !
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rw_on_xda:
maybe this:

Thank you very much!

I was able to get the tablet functional again & updated to Android 11 then flashed: https://xdaforums.com/t/rom-11-0-unofficial-nexus-stock-for-2019-galaxy-tab-a-10-1-sm-t510.4234889/

Do you happen to know how to get Magisk on it I've heard some mixed reports saying it's working some saying it is not.

And it was a long time ago I did Magisk on my former ROM before all this so I don't recall whether on this model we patch boot.img or recovery.img
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Just use TWRP to flash the Magisk23.apk file as if it were a zip.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaladhjin:
You can do that?

I thought TWRP only allowed flashing .zip & .img 🤔
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I thought the same thing till this came along. Flash it as if it were a zip. If it won't work, TWRP won't list it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaladhjin:
Did you rename .apk to .zip or actually just flash Magisk.apk?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Flash apk. Don't rename.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Krekle:
Thank you sir! I almost bricked my device, but then I managed to make it come alive again. Now I will heal my mental scars and go again with Andys OS!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] -=Guybrush=-:
Hello to everyone! :) I apologize in advance because I'm almost sure it has been asked before but I can't go through the whole 27 pages, I think you can understand.

A friend of mine owns a Galaxy Tab 10.1 2019 LTE so the SM-T515, not the T510. By what I've understood, the SoC is the same (Exynos 7904), the only relevant difference being cellular radio.

Samsung rom is awful and he can live without the cellular part so my question is "is it possible to flash this one?".

I don't deem it that easy but on YouTube there are claims it is possible. I don't trust them and that's why I'm asking here.

Thanks in advance for your advices and have a nice day! :)

EDIT:

I've taken a brief look at that blog mentioned in those YouTube videos. Well they link to @AndyYan's GSIs which are discussed here too, just a version which is no longer available.

Based on that advice and following the naming convention, I've guessed the right and current one to download should be this one:

https://sourceforge.net/projects/an...IAL-treble_arm64_bvS-vndklite.img.xz/download

I've also found a lot of valuable stuff and informations here and here. So... A lot of work to do but what I'm looking forward to achieve seems at least feasible (given that, as I expected, TWRP seems interchangeable between the two).

EDIT:

I've deepened my research furthermore and I've come along this thread where the opener (@AlexeyPer) states to have adapted a LOS 17.1 release from @Magendanz to use it on the SM-T515 BUT without working LTE (as I already expcted). It's fine as already explained BUT there it is adviced to use the TWRP still from @Magendanz which is downloadable here where I clearly read that it is strictly linked to the OEM version which is T510XXU5CUJ1. A counterpart for the T515 doesn't seem to exist: CUJ1 does actually exist but it is quite a different thing given that the binary revision (BIT) is 8 vs 5 so I don't know how to find a reference to the right kernel source and I'm quite stuck...

Also, I've found some references where it is said that by Odin I can downgrade with no issues at all, others where it is said that downgrading (especially to a lower BIT) is just impossible: what's the truth?

Thanks as always! :)

I ended with boot loop after updating to this from Lineage OS 16 using TWRP and in same condition as

But unlike above, my tablet restarts in 5 secs before I can hard reset (7 secs) as suggested in https://xdaforums.com/t/sm-t510-t515-2019-galaxy-tab-a-10-1-hard-resets.3927366/. I tried to get into download/recovery mode by following the steps for more than an hour. Still no luck. One alternative seems to wait for battery to empty which could take days!

Is there any alternative to go to download/recovery mode quicker?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
You have to click "Options" in Odin and uncheck "Auto reboot" to keep it from restarting on its own.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AMLenoir:
I tried doing this with LineageOS 18.1 and just ended up with a bootloop. Tried flashing GApps after flashing Lineage, got "failure to mount /system_root" and all file operations produce same error.

Also after flashing Lineage I don't get the typical "Wipe Dalvik cache" and "reboot" options I usually get after flashing a ROM.

Update: Solved the bootloop.

You want a64_bvS, not arm64. The Nexus stock is labeled with a64 in the device info.

I'm still getting the "failure to mount /system_root" error. Will keep working on it.

Update 2: Apparently solved by installing vndklite version of ROM. Now apparently facing an issue where trying to install OpenGApps makes my tablet scream at me (kid you not, it sounds like an alarm going off) about not being Play Protect certified. Tried to register it but no GSF was found on the ROM.

I was able to dirty flash it once and get the Lineage architecture alongside the Nexus apps and features, but I can't for the life of me remember how I did it or reproduce it.

There is no reason to waste time on Lineage OS 18.1 when Lineage OS 19.1 is almost ready.

This tablet runs ARM version of OS, but has ARM x64 hardware. Is there no way to port x64 OS on it?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I'm waiting on an MTP fix (#2270) before I release the LOS 19.1 build.

Samsung hasn't released a 64-bit OEM release for this device, so we'd have to adapt a vendor partition from a similar Exynos 7904 model like the Galaxy A40. If anyone has the time and skill to do this, please let me know.

Change Log:

20220417:

Based on the latest build of LineageOS 18.1 GSI (20220414) with April 2022 Security Patch.

Updated to the latest Android 11 OEM kernel and vendor partition (T510XXU5CVB1).

Update to TWRP v3.6.1 custom recovery on AOSP 11.

Replaced default wallpaper with custom one inspired by my Nexus ROMs.

Boots normally for offline (cold) charging.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sorinakis:
Applied it over 17.1, all good, rebooted and now it loops on boot loader. I am not even able to to go to target-Download, it just ignores my power+vol-dw / power+vol_up keys. this is going to be hard to restore :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] woutercools:
I was once in the same situation.

The solution was to let de battery drain completely, then connect the tablet to your pc and perform a start to bootloader (power+vol_up). Then flash with Odin.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I've never had to let the battery completely drain. The trick is to press and hold Power + Vol Down for exactly 7 seconds (just enough for it to reset), and then switch to Power + Vol Up or Vol Up + Vol Down to enter recovery or download mode, respectively. It takes a few tries to get the timing right, but definitely much faster than waiting for the battery to drain.

I suspect the problem above is that you didn't first flash the T510XXU5CVB1 OEM firmware before flashing the custom ROM. There is no dirty flash support from Lineage 17.1 to Lineage 18.1.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sorinakis:
of course I've tried a dirty flash, rules are for wimps :)

That was the plan, to let it drain, I was not aware of the 7 seconds thing. I'll try it right now.

LE: the 7 sec thing doesn't work, will have to wait for it to discharge - you know your ROM can keep my tablet working for almost a week without recharging? Why are you making it work so well, now I have a lot of time to wait :P
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] chris6273:
Same issue here I'm afraid. Followed the instructions to the letter as-well.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Okiera29:
I have had luck just timing it right. I have also just waited for the the bootloop to restart and then, while holding power and volume down, plugging into the PC really quick. I usually get everything set first, USB C plugged into the tablet and partially plugged into the PC. You can get the cable to just where it rests in the USB port, but is not seated. Hold down power and volume down. The minute the tablet goes dark plug the USB in. Continue to hold down the power and volume down till either the recovery or download screen shows up. Again, this might take a few tries. It is a long story why, but I got really good at it after a while as it took me about 2 weeks to find a version of 12.1 that would work with our tablet.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] chris6273:
I've finally managed to get it to work after flashing the stock ROM (Download mode by holding Vol Up + Vol Down on the bootloop) and starting from scratch. Once I had TWRP installed (By copying over TWRP files to stock firmware file & replacing two conflicts, running through Magisk patch then flash modified stock AP using Odin then run Magisk again after booting), I had to follow these steps:

Enter TWRP recovery (Vol Up + Power),

Factory reset via Wipe -> Format data,

Flash "lineage-18.1-20220417-unofficial-t510xxu5cvb1.zip" using TWRP,

Flash "Magisk-v24.3.apk" using TWRP,

Reboot,

Run Magisk and allow it to do its thing (Including reboot),

Success!

I'm unsure whether the Magisk stuff is necessary for everyone but if it is or is supposed to be common knowledge, it would be good to have the additional steps added to the OP instructions please.

Thank you @Magendanz for your hard work on this ROM.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sorinakis:
I had to wait for the battery to discharge, then I was able to put the tablet in Download mode by pressing Vol+ and Vol-.

Fired Ondin, installed the stock ROM, did the Date/Time trick to be able to see the OEM Unlock in Dev Settings, reboot Vol+&Vol- and unlock bootloader there, then it worked as intended.

The battery life is still amazing on this ROM, good job @Magendanz !
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] testUser89:
ROM works and can even be used with an older version of the security patches as long as you flash the correct (older) TWRP after flashing the ROM (although the pain of doing a full device update by flashing the newer stock rom first, is worth it).

But I have the following issue: I cannot connect to a specific WiFi network created by my Fritz Repeater 1750E, it is the one to which the device was connected before the upgrade of the ROM (I used an older version from last year before). All other wifi networks work.

It is basically the same issue as described here for the SM-T580:

https://xdaforums.com/t/wlan-wifi-c...lineage-18-1-release-january-22-2022.4398991/

It is stuck at "saved" and "Failed to connect to network". I am sure this is not a password issue. Anybody has got any ideas?

same with androidn 12
