does lineage as provided by electimon only work on android 11?
how does one downgrade to android 12?
i believe the preflash validation errors that i see are related to trying to replace the bootloader with an older one.
Does this mean the device is locked on android 12 and can not revert?
The lineage rom does not replace the bootloader, you can revert with lenovo smart assistant recovery mode, and stock is android 11

i have a s7 and it is android 8.
i want to it downgrade android 6.0
how can do it?
Once you've gone Android 8 you can't fully to get back Android 6.
You can use TWRP to flash an Android 6 ROM, but this will only rollback the ROM. Bootloader will still be Android 8, and having a different bootloader to ROM can cause bugs and issues.
This is also assuming you're on Exynos. If your device is Snapdragon you're **** out of luck.
I would like to install a GSI on my A22 5G but I'm using the Android 12 Firmware and I can't downgrade to Android 11 due to Rollback protection. The problem is that the bootloader verifies the system image with vbmeta and I don't have a blank vbmeta for Android 12.
Yes ive tried it and it works fine with all the features.
Hi!
I recently made an update to Android 12 (OxygenOS 12.1) on my AC2003. So I tried to install TWRP on it with this Version: https://twrp.me/oneplus/oneplusnord.html and with this one https://forum.xda-developers.com/t/...ficial-twrp-for-oneplus-nord-testing.4142149/ . The last one was working fine when I had Android 11 still. I set up the ADB drivers as mentioned here: https://developer.android.com/studio/run/win-usb but when I either try to flash or boot any of the 2 images nothing happens :/ any idea what I'm doing wrong?
from what i've gathered, twrp is not working with 12 on oos yet. msm back to 11 and sacrifice. sorry.
I'm trying to install lineage OS, but the installation I was on was broken and it wouldn't let me unlock the bootloader, so I had to downgrade.
The only downgrade I found was for global, so I downgraded from android 12 eu to android 11 global. Now I can't find a package for android 12 global.
Can I update with an android 12 eu package? The phone is GM1913, current version is 11.0.9.1GM21AA. Version I got an update file for is GM1913_11.H.30

You can. Doesn't seem to have a negative impact so far. I'm on lineageos 20 now with nikgapps.
I have Huawei Y9 2019 with unlocked bootloader running Pixel Experince Plus 12.1 and I want to go back to EMUI 9.1 because I saw in some threads that I need to have EMUI 9.1 Firmware installed and kernel 4.9.148 to run Android 13 GSIs but I am worried because I heard that flashing EMUI will lead to relock bootloader (Whatever the method, official or unofficial). Is this true? if so, how can I go back to EMUI without relock bootloader?
Check wether phone is Project Treble ready - what is required to flash GSIs. BTW: Android 13 GSIs ( experimental ) are available since February 1, 2023.

My phone is already supports Project Treble, I just want to go back to EMUI 9.1 (Last time was EMUI 9.0 before bootloader unlock). They say EMUI 9.1 with kernel 4.9.148 required to run Android 13 GSIs, Android 12 GSIs and below work well without any issues on my phone.
