Great ROM ! Installed ROM through TWRP and installed Magisk. Root is functional.

The issue is - USB transfer of files through the PC does not work. Device manager detects it as a MTP USB Device. I tried enabling the " Use USB for " file transfer in Lineage. Uninstalled drivers and reinstalled and replugged the device several times. It shows nothing in My computer. Any suggestions please ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
Alternative is to use MyPhoneExplorer where you can enable Wifi connection for data transfer or synchronization.

Hi there - I am searching now but - I am in a bootloop. I am moving up from some of Magendanz previous builds.

I went into TWRP (3.5.1?) and loaded the latest TWRP 3.7.0 to the BL slot. Then clicked on reboot and it is just boot looping through the boot loader unlocked warning, then the Samsung Galaxy TabA logo, blank screen - over and over again.

I have tried all the button push/hold combos I can think of but ... nothing.

Any help greatly appreciated.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
Which build, old build could be necessary to update firmware first.

Shutdown the tablet and go to download mode and use Odin.

https://www.hardreset.info/devices/samsung/samsung-galaxy-tab-a-101-2019/download-mode/
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
Thanks - but it won't let me shutdown either

But - I booted my windows laptop now - and with it plugged into the pc and Odin running I can get the loop to stop...

Press and hold Vol+ and Power​

When Logo blinks – quickly go to press and hold Vol+ and Vol-​

That brings up the blue odin download page.​

Actually - repeating to check my work - and it is even easier than that - just plug in the USB to the pc with Odin running (actually - Odin doesn't need to be running either...)and press and hold Vol+ and Vol- and it opens the blue custom OS warning screen.

But clicking key combo to shutdown just starts the boot loop.

I guess I am ready to Odin up to T510XXU5CWA1??

I was planning on reading up a bit more but - remind me of a few points

Do I want to load the BL from this stock rom?

Then - I load the AP and then the CSC?

Thanks for the quick reply!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
PS - Not 100% sure - but I would guess I was on Nexus_Stock_AQ_T510XXU3BTH4-20201130

And yes - I see what I did there - updated twrp to a new firmware rev without doing the firmware first.

I need to get more sleep at night and stop with the pizza after midnight...

Thanks again for your QUICK help!!

So before I brick this really good - do I want to "Odin" the BL over or since it is unlocked do I want to leave it alone?

Etc etc?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
The Nexus ROM is old. Flash the latest firmware T510XXU5CWA1 in AP slot of Odin application. After Restart phone again in download mode you can flash the custom ROM (tar) in AP slot. This tar include the TWRP.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
Yep - sorry - I Odin'd the stock BL, AP and CSC.

Started up - enabled developer and usb debugging

Then booted back into download and Odin'd LOS20 .tar over and the blue downloader screen on the tablet quickly says "Only official released binaries are allowed to be flashed(BOOT)"

So - thinking of Odin my old copy of the Nexus rom .tar over including the BL.

Reboot and enable developer and usb debugging.

Then Odin the new T510XXU5CWA1 over just the AP

Then boot and see where I am at??

I read the entire thread now - but not exactly sure the best way to get out of where I am at?

Thanks again @waterpolo for your help.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
Did you use the HOME_CSC to clear the data?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
Well - I have tried a bunch of different things - nothing helping here.

I think I have updated the bootloader and now I can't get it to rollback. I tried going back to my previous stock - Nope - I get a fail to flash.

Tried to Odin the newest Twrp - fail

I downloaded @waterpolo 's latest patched boot.img but think I need to get TWRP working before I can get that to help.

Sadly - I am getting comfortable with Odin and remember a few things - but I fear I have already messed it up and not sure how to get it solved.

Thanks again for any tips, tricks, ideas.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
The latest firmware must be your way out.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
No - is that the trick? Technically - I wiped the tablet with android factory reset prior to this entire process.

So I now just tried to Odin that over - success. It rebooted with a little android guy working spinning circle thing.

I verified USB debugging was still on and then tried to Odin LOS20.tar and got the same "Only official binaries..... " error.

Am I stuck at stock?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
@waterpolo - man thanks for hanging with me. Not sure what I am doing wrong. I got the factory update to Odin over. I confirmed - I'm running Android 11 now and Build - RP1A.200720.012.T510XXU5CWA1

I just don't know how to get twrp-3.7.0_11-0-T510XXU5CWA1-20230330.tar.md5 or lineage-20.0-20230901-UNOFFICIAL-T510XXU5CWA1.tar.md5 to Odin install.

Both are giving me "Only official released binaries are allowed to be flashed" errors.

I am using Odin3_v3.14.4.

I mean maybe I can live on STOCK 11 :ROFLMAO:

:ROFLMAO: - But I would love to see LOS20 on this.

Thanks again!

Below answer came from search with Google on XDA:
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
@waterpolo - thanks again for your help. I did a search and came up with KG:Prenormal stuff and lots of videos claiming some odd solutions. But my OEM Unlock toggle was always visible and on.

Anyway I slept on it and tried again today. Nothing really new - but this time TWRP went in successfully with Odin. It auto rebooted into TWRP and per the instructions in post 1 I did a factory reset wipe and then in TWRP I clicked reboot to download - this opened the light blue download screen on the T510 but it didn't have any of the verification or integrity checks. I was able to Odin install the LOS rom without any issues.

I am not sure why it worked today but I am happy and currently setting up Lineage on my newly revived Samsung!!

If anyone ends up here searching with a similar problem - one hint I can offer - if you ever do get into TWRP, then reboot into Download mode and it seems it doesn't have the "Official binaries..." check.

Hey waterpolo - Thanks again.

What about T505N?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
Did you flash a multidisabler as well.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
Nope - good catch. Now before I screw something up - I just flash this ontop of everything with TWRP?

Also - lots of folks are posting about flashing AndyYan gsi - is that something worth doing?

Thanks again,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
flash on top.

I did install a newer system partition of the AndyYan GSI.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wantpizza:
Re AndyYan GSI

1. To do that I will have to wipe my user partition - or just the system partition so nothing else has to get re-installed?

2. Did you notice any/ alot of improvements?

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
1. No data wipe. Only system partition install.

2. Security fixes

In thread https://xdaforums.com/t/lineageos-20-0-android-13-sm-t510.4566269/post-89486287 is mentioned that the LOS21 from Feb 2024 is working, but the build after not. May be this is also applicable for the latest build.

Suggestion to keep LOS20 which is working fine.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] brewer75:
Thanks, and I will just stay on my current build for a while. I saw that post but hoped Andy Yan had corrected the problem since he issued kind of rapid new builds on LOS 21. Oh well, l'll just keep trying his new ones and maybe one of these times it will work!

Duuuude, you haven't flashed a custom recovery, you're still using the stock Android recovery. You need to follow the instructions on page 1 of this forum.

Did you unlock the bootloader? Were you able to update the recovery or install TWRP? You won't be able to install LineageOS with the stock recovery installed.

Do you use Odin 3.14.4?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rw_on_xda:
something between download AND (load into odin OR the subsequence download to the Tab) damages the image somehow !

check list:

- USB2 ports tried (not USB3)

- odin was started with admin rights (ODIN right click => run as admin) ?

- any virus scanner active ? (try to run windows in safe mode, => F8 Key)

- bad RAM ?

- partly damaged filesystem (=> check disk)

- tried to exchange ODIN with same version (clean uninstall => new install)

- lastest Samsung driver in place (after new install => reboot needed)

- tried to start with a clean flash, e.g. flash stock => check bootloader/OEM => Magendanz image ....

same ODIN error flashing stock ???

- tried to flash with a different windows box ?

attached is a screenshot when the T510 is in download mode

look at the 2. last line !

RP SWREV: B:5 K:5 S:5

same on yours ?

if NOT or to get a clean state:

- reflash stock and let it full boot !

- recheck OEM and bootloader unlock !

both seems to be allways the best option, when all (see my check list) was okay

AFAIK, "B" stands for bootloader or binary and a mismatched binary is in the Odin error message !

maybe something with your last stock flash went wrong ... ?

other important lines are the 5. and the 6.: both should be "OFF" !

The error message is covering up what you are flashing, but going back to the original message, it appears you are trying to flash only the AP and not BL and CSC. If so, that is a problem, You should never flash AP without BL and CSC.

My mistake. I thought he was trying to install the latest stock ROM. The LOS ROM is based on the latest stock ROM so there is no reason in shouldn't flash. Weird. If flashing the latest stock ROM worked and dev and OEM re-enabled, I would try renaming the file to remove the .md5 extension and flash it just as a tar which skips the md5 check.

Hello, I'm trying to setup this rom with a google child account using family link. After adding the account and logging in to my main, it wants to update play services and fails (I've also tried using the latest MindTheGapps from the website). Any way of adding a child account to this rom or do I have to go back to stock for that?

Is there a possibility of having full arm64 support?

I want to use some apps that are arm64 only (youtube revanced for example) but this rom is arm32.

As far as i know the exynos SoC on the tablet is arm64.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] strikoo:
For me it's a lot responsive. I'm still blown away how much it's better. it's stable, and battery feels the same. I did a "dirty" upgrade. Just awesome.

I'm using revanced without issues. In this build name is a64 attached suggesting arm64.

Can you give annother app that doesn't work for you so I can test it?

@Magendanz

Thank you
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jimkoutso2008:
There is a difference between a64 and arm64.

a64 means arm32 with an arm64 binder. (Which I have 0 idea what that means).

Looking at hardware info apps I see that the os is running on arm32 (while the SoC being arm64) so there is no point in telling you an app that doesn't work.

And about revanced working, huh the installer was telling me that arm32 is not supported. Maybe they put support for arm32 now, will give it a test.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Stolper:
Thanks for this ROM, working like a charm! However I noticed it changed widevine to L3, coming from L1. I tried Universal SafetyNet Fix in Magisk and it passed SafetyNet checker. However it is not fixing the widevine issue. Is there any solution? I'm hoping it can still be fixed since I use it mainly as a video device.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I believe that just unlocking the bootloader changes the device to L3. It isn't the fault of the ROM. Personally, I think streaming in high res formats on a 10" screen, is a waste of resources anyway. But to each his own. If it is that important to you, and Magisk can't solve the issue, then your only recourse is the revert to stock and relock the bootloader.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wiljedat:
Thanks Magendanz, installation was relatively easy and the tab runs smoothly. Exept for two thingies;

1) When reboot I have to 'powerbutton' away the samsung bootloaderwarning (no biggie)

2) After screen timeout the screen blackens but then comes back up again. Have to switch it off with the physical on/off button to kill it. (no biggie either)

The powerbutton on reboot is not necessary. Wait a few seconds and you will see the LineageOS boot animation.
