TWRP and Encryption: important note
If you didn't follow this guide to decrypt your internal storage DO NOT factory reset user data using TWRP!** This will break your internal storage! If you need to perform factory reset while maintaining encryption- flash stock Recovery using fastboot and wipe data in it.
If you will wipe data in TWRP without decrypting your phone, your custom ROM will not be able to write to userdata (/data) partition, initial device setup will not finish ever.
Decrypted phones CAN factory reset through TWRP!
Installation steps:
- Backup all your internal-storage stuff
- Perform a factory reset
- Flash your GSI image to /system
- Flash the below ZIPs to get correct behavior
- Optionally, flash GApps
Restoring Camera:

Restoring essential functions:
- Flash the latest ZIP. It is highly recommended NOT TO skip this one!
Google Apps (GApps):
- Flash in TWRP an appropriate package from OpenGApps. Choose the correct Android version package for ARM64.
