Once booted, make this recovery permanent:

• as in the next section: install with the recovery.zip file.

Install with the recovery.zip file

If you already have a working recovery, you only need to have this file on you phone storage (no computer needed). And flash this zip file from your recovery.

Navigate to Install > select the recovery.zip file.
