Samsung Galaxy A42

Summary of what works and doesn't

How to install

1. Unlock bootloader
2. Install latest firmware version (of OneUI) to Android 12. I think to update the kernel so it will boot newer ROMS
3. Flash TWRP and VBmeta
4. Reboot into TWRP and follow these:
   • Format Data (you will lose all files)
   • Wipe Davlik, Cache, Data and System
5. Install Dynapatch zip.
6. Choose a GSI image and flash it in System
7. Reboot to System

Hardware support

Most Hardware will work on most newer ROMs.
