[ROM][OFFICIAL][13] LineageOS 20.0 for the SM-T290 (gtowifi)

[tymclrewhjbcpo]

It's been a while this tablet was running old software, so I decided to clean install lineageos but I'm facing with this error when I flash recovery.tar via odin and try to boot into recovery. The recovery.img was downloaded from lineageos downloads page. Bootloader is unlocked by the way, I'm stuck.

What bootloader version has your tablet? Check so in download mode.

Try to install TWRP 3.7.0 on it. Then use TWRP to flash the LineageOS ZIP.

The TWRP package will flash the Android 9 bootloader which will probably allow it to work.

I get SW REV CHECK FAIL : [aboot]Fused 4 > Binary 3 whenever I try to flash twrp, I believe it's due to me who made a unawarely mistake updated to version T290XXS4CWC1, the recent twrp is incompatible with bootloader 4 I think. Apparently, I'll stick with the stock rom onwards.

It is not that TWRP needs to change anything. This is due to Samsung's new policy which will reject to flash TWRP. At the moment there is no way to get around it and will probably need to stick indeed with the stock ROM.

Finally I'm running LOS 13 on my Tab A8 2019
But cost me 16 bucks, I bought a used motherboard from ebay that wasn't upgraded to latest bootloader

I just installed LOS 20.0 on my Sm-T290 And it's running very smooth, and everything works well. Thanks so much for this work.

Just installed latest nightly build, everything is smooth, but how can i get my ds4 controller work? Another BT controller works good, but ds4 just connecting, but not work at all, even i installed magisk module onecontroller.
Could someone check if dualshock controller works or not ?

UPD. rolled back on build 20-06 this is the last one with dualshock 4 supporting.
Last 2 builds from 27-06 and 04-07 there are no DS4 support

 

[Kaldun13]

I dont know why i decided to update fw using this instruction but as i had LOS20 installed with los recovery i got blue screen on boot "secure check fail : boot.img"
At the end of that instruction said after all of it if i have custom recovery Download this downgrade package, but the linked file "1-downgrade-aboot.tar" no more available.
So i stucked on it. Should i flash stock rom first ?

UPD just flashed last T290XXU3CVG3 official rom via odin, than installed LOS20 again.

Bootloader U4/s4 update killed every custom things.

Unfortunately, indeed. But let it be a warning for everyone. If your device still has an older bootloader, only maximize the upgrade to U3! U4 will make you need to stick with this slow stock ROM forever.

Is there not a way we can petition Samsung (& others) to unlock their boot loaders at end of life for their devices. Luckily I didn't have this issue but it would be nice to be able to use our hardware the way we want.

Lol, they want you to buy a new device instead. That's why the lock the bootloaders. Security is just a pretext.

Hello @lifehackerhansol,

If Android 14 becomes a stable release and gets published, plus LineageOS 21 of course, would you then upgrade this to LineageOS 21?

I think your device came with Android 10, isn't it? Currently, we do not really have a fix for this, but the screen is accessible over ADB with screen mirroring.
