Hello! I bought a Mi 4c about 7 months ago, and I recently ran into some problems with it, mostly beacuse of careless use (like letting it go on 0% battery, my fault). I probably fried the fastcharge, since it does not charge with anything over 5V/1A, and after a few weeks it just tried to reboot in my hand while I was sending a message. Since then it refuses to turn on, (just the MI logo appears and sits like that for days) and it doesn't get recognised by MI suite, or even PC. Neither the charging LED flash or anything. It is a 2gb/16gb version, and I wonder if it is possible to get a 3gb/32gb mainboard and use that instead, since I really don't want/have the money tho spend on a new phone. Thanks in advance for all the replies.
