Info:
Android version 12.1 (12L)
July 2022 patch
Tested on A217F & Dual SIM working
GApps included so you don't have to flash them
Part 1 - Unlocking bootloader:
Skip this if you've already done it.
1. Enable Developer Options, go to OEM Unlocking and turn it on.
2. Plug in phone to PC, restart the phone and right when it turns off, keep holding VOLUME DOWN + VOLUME UP till you see the Download Mode
3. Hold VOLUME UP to enter Bootloader Unlock mode
4. Press VOLUME UP to accept, and let the phone restart and erase
* To check if it worked, head back to Download mode and check if "OEM LOCK" is "OFF"
Part 2 - Flash recovery:
1. Download Odin and recovery U7/recovery U6/recovery U5
2. Put device to Download Mode (Hold VOLUME UP + VOLUME DOWN while plugging in phone to PC)
3. Open Odin and hit AP and select recovery file
4. (optional) go to Options tab and untick Auto Reboot
5. Hit start
* If it fails with error "Only official binaries are allowed to be flashed(recovery)", then boot device up, connect to internet, and then change Date to some time ago like January 5th 2022
Part 3 - Flash the ROM:
1. Download and Extract the ROM
2. Download the kernel
3. Download and Extract platform-tools (ADB and Fastboot)
4. Open up Command Prompt and cd into platform-tools folder
5. Plug in phone to PC, restart or turn off phone and hold VOLUME UP + POWER for about 5 seconds. You should enter Lineage Recovery.
6. Tap Advanced, then Enter Fastboot
7. Type in command prompt "fastboot flash system " and drag the ROM .img file and hit enter. This should take around 3 to 5 minutes.
8. Exit Fastboot mode on the phone and go to Apply Update, Apply from ADB
9. Type in command prompt "adb sideload " and drag the kernel .zip file and hit enter. Press Yes when the phone asks to.
10. Reboot the phone.
Notes:
* DO NOT APPLY A SCREEN LOCK, or else the settings app will crash along with the setup wizard, and if you do it from settings you won't be able to change it, disable it or enable fingerprint unlock
* SuperSU root is pre-installed so you can 'adb sideload ' the UPDATE-unSU.zip from recovery, then 'adb sideload ' the Magisk apk attached below ("app-debug.apk") after renaming it to .zip
