Device encryption not working #18

Open Rosendoktor opened 10 years ago

Rosendoktor commented 10 years ago

Device encryption does not work with CM11 on Galaxy S3 Mini. Battery is charged > 80%, PIN/Password is set. After starting device encryption a green android appears, but nothing else happens. Hitting the "back" button leads back to to settings menu.

This may help:

Encryption can be triggered on the terminal with the command

vdc cryptfs enablecrypto <inplace|wipe>

If option "inplace" is used to preserve existing data in /data, encryption fails. This is also what happens if encryption is triggered via UI.

If option "wipe" is used, /data gets partitioned as a new dm-crypt volume. After reboot, device encryption is present.

This interface does not like braces...

The command is

vdc cryptfs enablecrypto inplace|wipe newpasswordhere

It's probably related to F2FS filesystem. Try to reformat your /data to ext4 However, I'll check this issue later. Thanks for very detailed report.

Hi Marcin, i think you're right. I remember I've seen some f2fs partition in the output of the "mount" command right after flashing, now after applying device encryption, /data is mounted as ext4. Maybe this should be documented somehow to not confuse people.

Thanks for the great work, I really enjoy kitkat on the S3 mini. ;)

Just fyi i tried enabling encryption will all partitions being ext4 and it still doesn't work just like described above. Great rom btw :)

Hi Paul,

did you try the root shell commands I've posted?

This might work if you use ext4 on your /data partition (never tried):

vdc cryptfs enablecrypto inplace

This works like a charm for me, but wipes /data:

vdc cryptfs enablecrypto wipe

Cheers,

Robert
