Just a guess because that happened to me: are you using TWRP? Do you have a replaced screen? TWRP currently can't boot with some of them as the kernel doesn't support the screen. Lineage Recovery works fine in this case.I need help. How do you install an update? At LOS17 I was able to download and install it. That no longer works. I have now made everything new. Wipe System and Data. Then LOS18 from 3.6 and Mindgapps installed. Then restored all of my apps. Now I wanted to install today's update. Neither OTA update works nor the installation in recovery. Boot loop. What's wrong with that? Why is it? I've been flashing different systems for years, but there are only problems with LOS18. How do you install an update?
