This is all the phone does on reboot. Shows logos, warnings, the lineage OS animation, a split second of the lockscreen and then nothing. No button presses get any reaction so far other than holding power/vol down to get to fastboot and reboot from there.

The phone was completely fine till I enabled "invert colours" from the swipe down menu becuse of a annoyingly white website. 😢

Swiping about where the pattern should be makes the phone do some vibrations signalling a wrong pattern. I know that I only get so many pattern retries before the phone goes into an even more bricked state.

These are the times where I hate how secure phones have become. Unfortunately, the phone can't discern between a border patrol agent trying to scan my phone for terrorist activities and my personal laptop trying to enable adb for resetting a dumb setting.

@sophie You could try to enable TalkBack by pressing and holding both volume buttons. Caution: It's very different to use, read up on it first.
