How to uninstall treble? (revert back to stock condition)
Ye u can flash treble twrp from normal twrp.
You will have to find the magisk treble and flash it.It will work normally, no issues from me.
You don't unistall treble just the twrp,wipe vendor before doing so if u want to install normal roms again.(unless you mean the A/B partitioning and treble)

Unable to install Oreo GSI ROMs

Hello. I have an unlocked G8342, and I'm trying installing phh's GSI. But after I flashed the system image, I cannot boot my phone. It just shows "SONY" and then rebooted automatically.
I tried flashing the SW_binaries_for_Xperia_Android_9.0_2.3.2_v5_yoshino.img or SW_binaries_for_Xperia_Android_8.1.6.4_r1_v16_yoshino.img.
Before I unlock my phone, I've upgraded to the official Pie release. But what I'm installing is Oreo. Does this matter? Or what should I do in order to make it work?

if u dont backup ur TA partition before unlocking your bootloader, camera will not work on oreo gsi roms. I recommend u can try pie gsi roms, but it has worse camera quality and stability issues..

I just cannot even boot the GSI ROM. The camera might have issues, but it's not important right now...

what gsi rom are you trying to flash? Do you have TWRP installed? I have a SOV36 (Japan AU version) and it boots with most of all gsi's. Currently using omni rom.
Here is my steps for flashing.
1. boot into twrp
2. goto wipe and factory reset (don't wipe data, system or cache just factory reset)
3. flash img
3a. optional: goto wipe; repair and resize system (if you want gapps)
4. flash gapps
5. flash magisk if you want root
6. reboot
Hope this helps

I have tried the Phh's latest 9.0 GSI and RR's GSI and ERFAN's Q GSI and the official q GSI from Google.
None of them work, all stuck on the Sony boot logo

latest RR gsi did not work for me either but roms like omni, bootleggers, lineage 16 all booted on my SOV 36
Flash the lastest pie ftf, then follow sinkoo1979, instructions, also be sure you only flash ARM64-A versions.. I know Omni, Bliss and bootleggers work with imo bootleggers was the nicest but the unofficial one here has ceased development.. Use open camera for your pics...
The Roms are a hit or miss...make and keep a twrp backup handy...

GSI Roms on A40?

The Galaxy A40 is supported by the Treble project, which means that you can install GSI roms. I want to do this as well, with a Lineage OS rom.
Has anyone done this before? I have not gotten it to work.
Here is what I have done:
Installed the unoffical TWRP that is found on this forum.
After that I rooted the system with Magisk and disabled DM-Verity and Force Encryption with Magisk (when I flashed the VM-Derity zip it made my phone go in a bootloop).
Installed the Project Treble app and saw the socket thing. The A40 only has socket A and not A/B, so I need to use the image that is for socket A.
Booted into TWRP and factory reset the system. I have also tried formatting the system here but it did not work.
Flashed the image that is made for ARM64 and Socket A.
Factory reset the system again (you apparently had to do this when you flash GSI roms)
Try to boot to system.
I end up in a bootloop.
Anyone here that has managed to pull this off?

Root

I'm running Android 11 on my curtana. I can flash magisk through OrangeFox recovery but it doesn't seem to work. Deleting system files or magisk modules don't work. Any solution?

Question Has anyone managed to install GSI on Snapdragon s22+

I've tried both a patched recovery with fastbootd as well as the recently released unofficial TWRP and have had no luck flashing any GSI with the device just restarting before it enters the GSI boot animation. Has anyone has any luck?
