Can't activate any screen lock

Using /e/OS Troubleshooting
, ,
1

Hi everyone,

I’m experiencing a persistent issue with the screen lock on my Fairphone 5 running /e/OS (version 3.4)

  • Error message: “The screen lock has already been changed. Please try the new screen lock…” – even though no lock is set. Therefore I cannot actually set a screen lock.

  • What I’ve tried so far:

    • Re-flashing /e/OS

    • Factory reset (via Settings and Recovery).

    • ADB commands to delete locksettings.db (→ “Permission denied” without root).

    • Downgrading to an older /e/OS version.

  • USB debugging is enabled, but su doesn’t work (no root access).

  • TWRP is not available for the Fairphone 5 (as far as I know).

I need the screen lock for banking apps etc.

Logs: I’ve uploaded a filtered log (relevant lines only) here: :link: https://pastebin.com/awZnKRaC

Thanks in advance for your help!

Sounds like FPR (if you used a google account on the FP5 before the switch to /e/OS applies):

TLDR; you need to go back to stock delete the connection google has with your device then install /e/OS again.

@XPhoEniX … Factory Reset Protection hashtag frp would improve the search :slightly_smiling_face: all Google accounts, passwords and PINs must be removed before install /e/OS.

you probably run an /e/ official build

Thank you so much, that did the job!

Could maybe elaborate what exactly did the job…?

To restore the original Android OS, then delete any Google account and screenlock and then reinstall e/OS. That took a while :smiley:
