Regarding TWRP-compatible encryption, I just tried the following …
- Installed LineageOS 14.1
- Set screen lock to “None”
- Encrypted the phone
- Wiped the phone in TWRP
- Installed 16.0
When booting 16.0, I was then surprised when I got asked for a decryption password, when none was set.
For the record:
- The required password in this case indeed seems to be “none”
. - Decryption stays unsuccessful this way
.
Other passwords are being declared as “Wrong password”, while “none” results in the “Decryption unsuccessful” screen.
