@_mone Will this custom ROM have more builds? There are a lot of details that I found amazing and I really wanted new builds to be released. I'm also having problems with apps in the factory system, I can't install because Android is 5.1.1. Thing this ROM solves. Keep developing, it's magnificent so far and we believe (at least I believe) that it can help hundreds or even thousands of people who have the Sm-T280. :)We support you and we don't want her to be left in the way.

Hello,

first of all, thank you for porting @_mone.

Unfortunatly GPS still seems not to be working correctly. I get an almost instant 3D fix with GPS test after flashing this stock ROM: T280XXS0ARJ2_T280AUT0ARJ2_HOME.tar.md5. As soon as i install the last linage OS, it won't accquire more than ten satellites and never get fix. Also GPS time is set to somewhen in 1979.

Is there any chance to fix this?

Regards,

Frankie
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] baucelabs:
I'd like to try this Lineage build, but it says firmware required is: T280XXS0ARJ2

I did a factory reset and my firmware is T280XXS0ARK3/T280XAC0ARK3.

Device says that the latest updates are already installed.

Would this build potentially still work on my device, or might attempting flash brick it?

Would my process be to flash the required firmware instead, even though it's for a completely different region? (No North American/Canadian regions for T280XXS0ARJ2.)

Can't find a source for these firmware roms that isn't sketchy or doesn't require installing malware.

edit: scratch that... I have a Galaxy Tab A6.. I'm out of luck I guess... very odd that the model number matches SM-T280.. is it really the same model for both A6 and A7?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] baucelabs:
So I found a source for my stock firmware as well as the required firmware for this build of Lineage.

Apparently even though my device says "A 6" when it boots.. apparently it's still a "Samsung Galaxy Tab A (2016, 7.0, Wi-Fi)". The naming conventions are confusing.

I guess I'll give this a try later, since I should be able to restore stock firmware if something goes wrong.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] chomsky55:
Could you post a link to that firmware please.

I flashed this ROM on my tab A 6 and now I get a error when booting: custom binary blocked by frp lock. The tablet shuts down after that so I'm kinda screwed if this ROM doesn't work and I'll have to go back to the official firmware which is android 5.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] fassal:
I think this is because there was still a google account in use on that device before. There are manuals how to fix this (something like removing the google account or disabling android device protection). Also make sure to enable OEM-Unlock in developer settings while using the stock ROM. I also suggest downloading stock firmware with SamloaderKotlin from the official samsung server.

I didn't read that line (idiot me) and after flashing the ROM, the tablet just bootloops into the LOS animation.

Is there a way to go back to stock ROM?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DallasBelt:
Okay, I was able to go back to stock firmware. But if it is not from the same region that the custom ROM requires, can I flash the T280XXS0ARJ2 one and then flash LOS? Or the bootloop I got it's not related to that?

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Rainshine:
Appreciate any troubleshooting tips; From TWRP I did the standard wipe/install/mount/install, and everything seems to be fine. No bloatware, running faster, no 3.5 GB of space inexplicably gone.

Except. I basically only use the tablet for three things: VLC OTG, reading ebooks, and Pandora.

I've got no sound. I thought I heard some sound at some point during the first power on, but I definitely don't have any now. No speaker, no wired headphone, no bluetooth sound. Multiple reboots, went in and played with the sound levels, I can't get it to make a peep, and could use some tips to figure out what's wrong.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] tmuhlhausen:
i have tried flashing this multiple ways with success, upon reboot it gets FAP locked
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] tmuhlhausen:
i have successfully installed it, and preformed a reinstalling using ARM Nano 7.1 Gapps. i am unsure why the first time i got an FRP lock. i managed to install it with odin to flash the recovery then quickly booting into the recovery and installing the lineage14 ZIP package with ADB, whilst also wiping dalvik cache & cache. Once finished then i mounted the system still inside twrp 3.4.0-3, and de-selected wiping dalvik and the cache going into ADB sideload. on the computer i initiated the command in adb to sideload the gapps and upon reboot everything looked proper. i will edit though if i encounter issues. mind you..... i am not connected to the internet yet.

EDIT: Absolutely Impressed... no crashes or FRP locks and the rom is extremely stable minus the fact the camera does not work obviously. Which is not a big deal... you just have to download any standard camera apk for android 7.1.2 and sideload it before you boot your rom inside the recovery.

There is not much need for a new rom for this model considering its hardware capability is almost maxed out as is, i was going with the impression this version of lineage 14.1 was not stable based on my own and others reactions. but it is however a stable rom and seems to be suffient for this tablet

I did find some difference. For example CPU speed and RAM:

Samsung Galaxy Tab A7 4 x 2GHz & 4 x 1.8GHz (Qualcomm Snapdragon 662)

RAM 3GB

Samsung Galaxy Tab S6 Lite LTE

4 x 2.3GHz & 4 x 1.7GHz (Samsung Exynos 9611)

RAM 4GB

I think if the CPU is not the same it could be that this ROM is working. But I don't understand that. Does anyone know if it works or not?

Hey,

can someone please explain to me why it matters that the device had the stock ROM "T280XXS0ARJ2" installed before?

I've had no clue what ROM my device was using so I installed LineageOS 14.1 ("lineage-14.1-20210209-UNOFFICIAL-gtexswifi.zip") anyways and it works - except for audio.

I did more research and found my device reports [ro.boot.bootloader]: [T280XXU0AQA4]
[ro.bootloader]: [T280XXU0AQA4] using getprop.

So I guess this means I was using T280XXU0AQA4 before?

According to https://samfrew.com/de/model/SM-T280/region/DBT/ these were the last two versions.

Since I try to understand what a custom ROM actually modifies and what not, I want to understand why this matters (assuming the sound would work if I installed T280XXS0ARJ2 and then LineageOS again).

The LineageOS replaces boot (kernel) and system, right? So these can't be relevant.

But what on the stock samsung ROM is different between T280XXS0ARJ2 and T280XXU0AQA4 that can have an impact on the audio? Is it the bootloader?

btw: For those having issues rooting LineageOS 14.1 with SuperSU: I had the same issues and patched the SuperSU installer for my SM-T280. I guess it should work for everyone: https://xdaforums.com/t/sm-t280-sup...es-broken-kernel-image.4492241/#post-87434813
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] RFZ:
So, I compared T280XXS0ARJ2 and T280XXU0AQA4, and it raised more questions ;)

Are these stock ROMs incremental updates?! The latest one is missing some files...

I guess the bootloader is sboot/sboot2, so updating to T280XXS0ARJ2 won't change it.

SPRDCP/SPRDDSP are identical, so they won't change anything either.

system and boot are irrelevant when I install LineageOS afterwards.

recovery is irrelevant.

So what could make a difference are cache and hidden. cache is not really relevant to run the device, but the fact that it is included in the update implies that it probably contains stuff that will run once when the device is first booted after the update? 🤔

Where does the String [ro.bootloader]: [T280XXU0AQA4] come from? If it comes from the bootloader, then it would show T280XXU0AQA4 even when I actually run on T280XXS0ARJ2 🤔

So I can't even be sure if my device was running on T280XXU0AQA4 or T280XXS0ARJ2 before I installed LineageOS 14.1?

EDIT: Never mind... I noticed I had audio when using the headphone jack. Since the tablet was disassembled before (battery replaced) I assumed maybe it was a hardware issue. I disassembled and assembled it again and now the audio works.

So I guess I can confirm it also works fine with T280XXU0AQA4 ;)

Today recently, I have returned from the stock rom, I installed it normally, adding to the steps, format the data.

(Update) I've noticed that if I leave the Bluetooth on, the problem with the wifi disconnecting disappears for good. And with the random reboots, I haven't been able to find a solution, but I have noticed that if an application is the problem, installing an old version, it works without reboots.
