Lockscreen loop


My device is locked (one lockscreen) after upgrade from Q to R.
After reboot I enter my Pin number to unlock sim card and after that it ask me for my pin to unlock my phone. The issue is that after 1second it ask me for my pin code again and again for ever.
I tried to reboot but it is the same.
I tried a wrong pin and it tells me that it’s wrong and it is different. So I know I did the right pin but it loops.
Please help, I am locked out of my phone.
Can I remove the lock screen from recovery ?
What can I do ?

I follow this guide to upgrade : https://doc.e.foundation/devices/z3c/upgrade
I downloaded this one : e-1.17-r-20231113351093-dev-z3c.zip

Thank for your help

Ok I solved it by myself after 2 hours :

  1. reboot on recovery
  2. “enable ADB”
  3. on pc : adb shell
  4. mount /dev/block/by-name/userdata /data
  5. mv /data/system/locksettings.db /data/system/locksettings.db.OLD or rm /data/system/locksettings.db
  6. umount /data/
  7. exit
  8. reboot

It should remove lock screen

Please /e/ add a warning on https://doc.e.foundation/devices/z3c/upgrade : “remove lock screen before upgrade”
