For any boot loop related issues on Lineage, flashing the boot partition with the boot.img provided by Lineage for your system will almost always fix the problem (as you found out just now). If not, then re-doing all the steps in the installation guide for your device should do the trick. I was also getting a bootloop on my rooted phone, but I was running Kitsune Magisk. Switching to regular Magisk did not cause any bootloops. Not sure what caused the bootloop considering I was running Kitsune just fine for a couple months until the bootloop happened. Maybe some system update screwed things up?

My bank’s website is a bit dogshit to say the least, but I have not yet tried MicroG, so I’ll do that next. Thanks a lot.

EDIT: No luck, MicroG does not work

aye, thanks!

ah damn and i wanted to guess unihertz but decided not to lol. i was thinking about getting a brick like that but their custom ROM support (or lack thereof) puts me off. is the stock OS bearable on your unihertz?

let me guess, Ulefone, Doogee, or Oukitel?
