Can you provide kernel source, device trees and vendor trees?

 

[tqmatvey]

after flashing and testing for a bit i noticed that Shim level is way higher than on stock or any gsi i have used
the higher the brightness, the worse the situation is.

after opening and closing any app, its back to normal a bit better but shim is still very high and noticable compared to any gsi or stock

turned off the device (didnt shutdown) after a minute or so, turned on, it flickered and shim is back until opening any app

if you are interested in more details or logs, let me know

i will have this build flashed for at least few days to test

hi! thank you for feed back.
brightness value are default. not device related. pls check vendor overlay.
Atm dont have pbty to share device/vendor.
Kernel is here https://forum.xda-developers.com/t/...tb128xu-kernel-sources.4583191/#post-88570739 dtb and dtbo are used from stock.

 

[tqmatvey]

you may want to add direct github kernel link to main post since its required by xda gpl rules, your post may get banned and we definately dont want that xD

Hi! Thanks for sharing your work on the forum. As per the post above, we require a direct link to the kernel source in the first post to ensure GPL compliance. As a courtesy, I've edited the first post and added that for you (from the source link you have mentioned in your other thread), so you're good to go. But please remember to do so in the future whenever you're creating threads sharing your development work.

uhhhh

LOS-20.0-20230611v2-UNOFFICIAL-tb128fu.zip

i kinda "semi-hard bricked" the tablet... not with the ROM, but in some other way, can you pm me on telegram if you could help?...

 

[tqmatvey]

and i cant properly flash lineage now, it crashes the moment i start flashing it.., flashing super_1 to super doesnt fix it

 

[tqmatvey]

welp, after flashing all the partitions manually, i ended up in crashdump, thats my "semi-hard brick", only stock flobal fw kernel works, any other kernel, zui, CAF, crashdump...

 

[tqmatvey]

flashed stock kernel from global fw and lineage booted, everything is laggy (also thanks to my semi-hard brick), i guess this tablet can just go to the shelf...

 

[tqmatvey]

oh **** and i dont have wifi unless i flash stock vendor with stock kernel :| and the display doesnt rotate at all, even if i force landscape, it stays in portrait.. bug of stock kernel. please help, i just dont know what to do, flashing zui from qfil doesnt help too...

actually before flashing stock vendor, it doesnt lag

Hi!

Thank you for your work! I wanna flash Lineage OS in this tablet but I dont know how to do it. Can someone tell me where I can find TWRP and how to flash it?

Thanks

 

[ajesushn]

Hi everyone! Hope you are fine

I tried to flash Lineage OS today and I couldnt do it. I flashed TWRP (no root) but it couldnt flash zip. It just said It couldnt do it.

I tried to flash super.img but i dont know where are the super partition to format. I went to wipe menu of twrp and there wasnt a super partition, just “ART/Dalvik”, “SD card”, etc, but nothing called “Super”.

Anyway I tried flash super1.img from original firmware with twrp flashing image menu and after reboot I saw black screen with Qualcomm Crashdump text. In flash menu I could see a “super_…” partition but there wasnt it in wipe menu.

After that I prayed to all Saints to restore global rom and I had good luck and thats all.

As can you see I need a little tutorial to do it, If any caritative person wanna share his knowledge please thank you

PD: i dont flash any rom since I had my last android device five years ago. I just used CWM, zip files and thats all. I see that this procedures are more difficult nowadays

@ajesushn use lineage recovery, unzip, flash to recovery, reboot to lineage recovery, fastboot mode > flash super_1.img, sideload latest lineage, reboot recovery so that it switches slots, flash other stuff you need (gapps, microg, magisk) you choose, format data , boot to system

for now quite sad that the device trees aren't public, would love to get crdroid working for the tb128fu

Thank you for the recovery. Just a doubt: there are 2 lineage20 zips. Which works better? I read your replies and the update seems that give more issues than fixes

as i clearly mentioned, my issues were caused by another thing, not lineage related, latest lineage 20 works perfectly

 

[ajesushn]

Thank you. Install LineageOS successfully. Everything works great and very fluid. I haven't found any problem so far.
