Hello!
I am facing this problem and i dont know what to do.
I installed the rom normally, everything worked... then I noticed I'm on 10% of battery. Ok, i connected the charger and it says slow charging. Did some research and found that a magisk module should fix this problem. Installed magisk, but before I could install the module the phone literally died. I got this low battery icon whenever i try to turn on the phone. Its on the charger for 4 hours now and nothing. Notification led constantly blinking. I cant access neither fastboot nor recovery because this low battery icon (it shows that the phone is charging but not). Tried with a bigger charger, nothing.
I have never had any problem with battery. Fast charging worked perfectly wih previous rom.
If anyone can help i would be very thankful.
