Nightly updates start failing

After a few days, nightly upgrades started to fail, with

assert failed: op3.verify_modem("2018-12-06 00:49:
24") == "1"
Updater process ended with ERROR: 7
Error installing zip file '/data/lineageos_updates/'
Updating partition details...

Updating TWRP did not help.


cp twrp-3.2.3-1-oneplus3.img twrp.img
adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot

The problem appeared to be modem compatibility, so:

Update firmware and modem

Latest was

adb push /sdcard

Go into recovery and update with TWRP.

After this, nightly updates work again.

Nightly updates start failing again (June 2019)

This happened around the update of 16th June.

I noticed that there was a new firmware

After flashing this, I could not unlock the lock screen with PIN.

Reverted to, disabled screen locking, flashed Now nightly updates work again.

But: I could not set a PIN again, because a PIN is needed to set the PIN, and it would not accept the old PIN.

In TWRP’s file manager I deleted /data/system/locksettings.db.

After rebooting, all was well.
