Clean flash.Advice needed
TL;DR Phone keeps getting System UI crashes and CPU goes up to 83 degrees while charging.
So, I dirty flashed v.4.8 few days after installing for the first time v.4.6 on my H870. Got Pico Gapps and Magisk as well (didn't dirty flash them during the upgrade though).
Now I keep getting System UI crashes constantly, which drives me crazy as I can only do a forced reboot, which often ends up in a cycle of two or three automatic reboots.
During charge CPU temperature goes as high as 83 degrees (!) due to iorap service, which keeps running indefinitely with high resource usage.
(If I understand correctly, /system/bin/iorap.cmd.compiler is the new pre-fetching service by Google, but I didn't find much about it).
Battery temperature is OK.
So the phone is pretty much unusable. Does anyone have these kind of problems?
I'm afraid even a clean flash would not solve this situation, and I'm thinking that if I have to reinstall everything from scratch, I would rather go back to stock rom and see if I can debloat and root it (didn't dig this route yet though).
Any suggestion or comment?
