For me, the only use case of this tablet is to run just one app (UWorld Medical), but it requires Android 9 or higher. I installed this custom ROM but it won't work since it is Android 7. Is there any way I can actually run that app? Otherwise, this tablet is just an old brick for me. Thanks!

I installed lineage without gapps, because I accidentally downloaded arm-64 instead of the arm version. I then wiped, formatted, then reinstalled lineage and the arm 7.1 pico gapps. It appears to install successfully but when I set up lineage there is no google sign in, and then once I am set up and in, there arent any google apps. I clicked mount, then selected system, then went into settings and unticked the setting that says "unmount system before installing zip". Is that the correct thing to do? Anyone know how to fix this?

I installed this rom on this tablet. The ROM is not official. One of the problems is that while using the tablet, it makes a popping noise and restarts. 2nd video is not shot. 3. Own camera app not working. Another application needs to be installed. 4.

The microphone does not work when making a video call. He has some problems. Is this ROM related? Should I install another ROM or go back to stock ROM? I don't want to go back to Stock Rome because it's old and slow

Hello,

I managed to install LineageOS following these instructions, but I can't seem to get GApps installed.

Thanks for replying! I managed to solve it in the end. What I had to do was install and boot up LineageOS, then reboot into TWRP once more, factory reset (don't know if needed), mount system partition and install GApps, rather than trying to install both at the same time.

Congratulations on the great job.

I finally managed to take a breath of my children's tablets.

Regarding the problem of adding the memory card, as internal memory. This error does not occur in version 20200512. With that, just install it. Do the procedure and update to the latest version.

The only thing I did, which is not mandatory to do, was to convert my card to EXT4.

Regarding the camera problem. Just install another camera app.

So far everything working.

But thanks once for the great job.

I managed to get into the TWRP 3.4.0.1 but I'm not able to install the rom, I'm getting this:

Updater process ended with ERROR: 7

[edit] tied to install May and September builds also tried to install by removing the asserts line but I'm still getting the error below:

Error installing Zip file '/external_sd/OS/lineage-14.1-20200903-UNOFFICIAL-gtexswifi.zip'

does anyone knows how to fix this issue?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] syan8182:
I figured out, you have to immediately press volume up and center button after the manual reboot from ODIN flash. hope this helps others.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] barrie.kenyon:
Hi Guys

I have figured out what causes my 'Custom binary blocked by FRP Lock' problem, but I am not sure how to fix it!

As suggested by _mone, I have downloaded and installed the stock Samsung T280 ROM. ODIN loaded it OK, but it then bootlooped with 'Google Services failed to load'. I booted into Android recovery, wiped everything, and it then booted into Android 5.1.1 OK.

I used ODIN to load TWRP, booted into TWRP, installed lineage-14.1-20200908 and Gapps, rebooted into Android 7.1.2 fine. Fiddled around for a bit, and then deliberately rebooted to see if it came up OK. Came up fine.

On the web FRP appears to be associated with your google account, so I now set up my Google account, loaded an app from PlayStore, all OK.

I rebooted and I am now back at the 'Custom binary blocked by FRP Lock'

so now I know what causes it, but how do i cure it?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] JuanISC:
I got it, also you can uncheck the reboot option in the second tab in Odin, then you dont need to intermediately press the power+vol up, you still need to press that combo in order to boot into TWRP

anyone found how to bypass that error 7 message? I'm very exited to try this on my old tablet, kudos to the devs involved.

I'm subscribing to get latest news updates for this.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] syan8182:
I am getting the same Updater process ended with ERROR: 7, when trying to update from May version to the latest version on 0908. I am just going to format and wipe evertthing and do a fresh install of the latest version.

How do we properly update the rom if there is a future update? like a dirty flash. Appreciated.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Fraser06:
I've observed that ERROR: 7 appears whenever you do some sort of wiping, however it doesn't appear when you try flashing again after rebooting to recovery. So I suggest trying a process like this: wipe->reboot to recovery->flash rom->reboot

I've found a way to bypass FRP or rather actually disable it, just flash the FRP Destroyer.zip from this thread. I personally used FRP + DM Verity + Force Encrypt Remover.zip and so far it's been fine. It essentially removes the partition FRP uses to store the Google account the device is locked with. I'm not aware of any issues from doing this, so as always, flash at your own risk.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Volkan2008:
Search twrp error 7 in google

i made it by unzipping the rom, entering the unzipped folder META INF --> com --> google --> android, than opening the updater script file with notepad ++. After opening it I deleted the first line and zip the rom again. Thats it

sorry If ı used english bad :D

[MENTION=6847876]_mone[/MENTION]:

First of all a big, big thanks for this rom ! Great work and exactly the rom that I was waiting for ... :) :)

May I ask you a question about MicroG ?

As far as this is not an official LOS build, is it possible to include the 'signature spoofing patch' (https://github.com/microg/android_pa...master/patches) into this rom ?

Or, alternativly, include MicroG 'completly' into the rom ?

The reason why I ask is that I think there are a lot of people around who like to have a Google-free phone (without GAPPS), but like to have messaging and location services that is provided by MicroG. The inclusion of the signature spoofing patch would be an important first step for installing MicroG by ourself ..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Fraser06:
What I mean by wiping is by doing any wipe command prior to installing the rom, say wiping the cache. When the error appeared in my device, I just rebooted it to recovery again and tried to install it. It worked that way for me, but if it doesn't work for you, you could instead try [MENTION=11105955]Volkan2008[/MENTION]'s advice a few posts above me and modify the zip by deleting some lines in the updater script.

I've had the same issue after the flash of the newest TWRP ...

So my tested fully working steps are:

- Flash stock rom

- Enable developer options in stock

- Enable USB debugging and unlock bootloader (don't know the right english term)

- Flash TRWP 3.4.0-1_mone...tar in ODIN

- As soon as the tablet boots reboot in recovery (HOME + VOL UP + POWER)

(because the 3.4.0-2_mone...tar doesn't boot after the flash)

- In TWRP install 3.4.0-2_mone...img , then reboot recovery

- In TWRP wipe cache/dalvik/data, then format data

- In TWRP install the rom

(+ install widivine blobs if needed)

(+ install Magisk 20.4 if needed)

- Reboot system (first boot will take around 5 minutes, so be patient ..;) )

The stock rom can be downloaded via SamFirm (windows programm), should be easy to find :)

---------- Post added at 08:51 PM ---------- Previous post was at 08:31 PM ----------

@_mone:

Found two issues (except these the rom is fantastic, thanks for your hard work :) )

Like already mentioned the camera is crap ..

But that doesn't matter that much because open camera work perfect. Can be found in FDroid store or even Google play store

However most tested other camera apps aren't working too, so imho something with the camera api is broken/incorrect ..

Maybe you can cheek the LOS14 devices trees of the SM-T580 (gtaxlwifi) or even SM-G800F (kminilte) of the for an optimized code ?

The developer of the kminilte (spookcity) had the same issues in his first LOS14 builds, but found a perfect fix ..

Second issue is the GPS

This doesn't work for me, no satellites found (neither gps nor glonass), all satellite-testing apps will fail or at least report that they couldn't find any ..

I don't have any workround yet for the gps location issue, tips/hints warmly welcome :)

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] _mone:
Apologies for this recovery mess with ODIN, but this device has "secure boot" enabled and we need special tools to sign the .img. We now have them!

I've uploaded a new recovery build (TWRP-3.4.0-3).

The 3rd is always the good-one, right!? It should be!

From now on our recovery.img and boot.img will be properly signed as the stock-ones, so there shouldn't be anymore issues with ODIN.

See this and this commit for the tools.

As always: Flash at your own risk. If anyone flash it with ODIN let me know how it goes.

P.S.: I'm reading every post in this thread and I'm aware of bugs and suggestions reported.

Can you confirm the gps issue ?

I'm not sure whether it is my single problem because I've patched your rom with the nanodroid-patcher to be able to install MicroG. Maybe it's an MicroG issue ?

Another question:

Adaptive brightness isn't implemented but I think that wasn't in stock also, right ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] barrie.kenyon:
Hi, and thank you to _mone!

I have now got my T280 running the latest rom. A steep learning curve, but I am finally there.

My first install was blocked by 'FRP Lock' when I rebooted. As suggested by _mone, I reloaded the stock rom and started again.

This time I loaded up the lineage rom and gapps, and found an FRP removal site at samsungsfour.com. It did not work for me. Back to loading the stock rom, and start again.

This time I used the 'FRP Destroyer - flashable zip' suggested by Fraser06 and it has worked. I came across the wipe problem, rebooted into recovery again and it loaded up with no further trouble. I loaded the Open Camera app, also fine.

My T280 now runs the new rom and everything works. Emails, web browsing, BBC News, Cool Reader ebook app, sudoku, Facebook, fantastic!

Thank you to _mone and all the other people who have provided advice and guidance.

Keep up the good work. (I am looking forward to Lineage 17.1 now!)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] _mone:
Yes. No gps at all. I was working on it this morning.. no success yet.

About adaptive brightness.. not sure about stock but we don't have a light sensor so i guess it wasn't implemented in stock neither.
