alright it works but now the problem is when i try to do the kernel change twrp freezes and it starts again
What TWRP do you use?
Aight, did you use the brightness fix zip or the .sh script? The zip one doesn't work, the .sh script can be found here: https://forum.xda-developers.com/t/...laxy-tab-a7-10-4-2020-lineageos-18-1.4295985/ (If you did use the zip then try this script, it should work and there is a tutorial in that post)
wait i tried the fix and it still doesnt work... weeeirdAight, did you use the brightness fix zip or the .sh script?

Would you be also able to make a kernel and twrp after this device gets Android 12 from Samsung?
Unless FBE is disabled, this behaviour is typical behaviourI have a working GSI version of Lineage 19.1 on my SM-T500 using this thread:
Hello world, I have successfully built LineageOS 19.1 with Gapps for the SM-T500 (Tab A7 10.4 2020) using Andy Yan's LOS GSIs. Lineage is current as of 3/24/2022. I have also compiled TWRP version 3.6.1, based on Android 11 (previous release...forum.xda-developers.com
However that version of TWRP would always boot back into TWRP unless you used his exit_twrp command. So I decided to install the version of TWRP in this thread. It seems to work fine. It boots into System as desired.
My issue, which is a minor one, is that each time I boot back into TWRP it goes back to the default brightness level in TWRP with the screen timeout box checked. It also does not retain the date/time setting used in the past session. The time and date is wrong. The date is an issue because of the default backup file name date code is always the same. Is this typical or am I missing something? Any suggestions?
(Both versions of TWRP had this issue.)

Thanks for bringing a nicer TWRP for GSI loading to our devices. I flashed this with no issues, but I am really struggling to get my device to boot any GSI. I am sure it is something that I am doing wrong on my end, since I have not messed with Samsung devices or any GSI installations before. Is there a change to have a more in-depth guide written up on installing a GSI on our device, or is there one already available that has similar instructions? I am planning on starting from scratch once I get home, and would like to have all of my ducks in a row before attempting again.
