Description
Setting up encryption on LineageOS installed on the Nextbit Robin seems to cause issues for TWRP trying to decrypt the partition.
What I tried so far:
- Set the pattern to represent the code "123456789", enabled pattern prompt during boot up, trying that pattern in TWRP, results in
Failed to decrypt data - Set the pattern to represent the code "123456789", enabled pattern prompt during boot up, trying to unlock with vdc over ADB, results in
/sbin/sh: vdc: not found - Set the passcode to
1234, disabled password prompt during boot up, TWRP asks for a passphrase (not a passcode), trying1234ordefault_passwordresult inFailed to decrypt data
dmesg in the recovery prints this while trying to unlock the phone:
