cannot get super user access when changing encryption passphrase
I know there has been multiple reports of this in the past (#1, #2, #21) but this is again a problem on Android 7 (fairphone OS "saibon" 15.02). The phone is rooted and I have the root permissions ("Root access: apps only" in Settings -> Developer options
). I get prompted to grant super user access to the app, and I do, permanently. Yet it still fails with the error:
Cannot get superuser access, exiting
... when I tap the "Change encryption password" button in the app's UI. It seems that the fixes for #2 need to be updated again here.
Or is there a way to do this without the app, I would be happy as well... As specified elsewhere, using a root shell you can change the encryption password separately using:
vdc cryptfs changepw password <current_PIN> password <new_passphrase>
This is similar to the problem with Cryptfs Password, see https://github.com/nelenkov/cryptfs-password-manager/issues/20
I can also confirm that the enforcement of a limited number of unlock attempts is not working either.
I ended up using this app with the manual encryption setup process.
