Tried the last (wiped, restored /system, /data, and cache from my backup). PIN still doesn't work. Do I need to restore another partition to fix it?18.1 worked fine on my US996, except for fingerprint sensor, so I did a TWRP backup (was on the 2021-04-29 nightly), then flashed Nougat (10n) KDZ and re-rooted. All good; phone booted into stock rooted Nougat fine. Re-booted to TWRP, wiped, restored my 18.1 setup and Magisk 23.0, then dirty-flashed the 2021-05-13 update. It boots up fine, but I can't unlock the phone (PIN won't work). Is there a default PIN on Lineage? Another way to remove the PIN lock? Or do I have to start over with a clean flash of the new ROM?
Maybe wipe, restore previous setup (2021-04-29) again, remove PIN lock, then dirty flash?
