I had to replace the I/O daughter board because of my charging port not working once i did it was working fine but after a night of charging and on the bus the next day i attempted to charge it again and it came back with this warning.
It gave me reason to believe my charger or battery was the issue so i put the old one back in and now it does the same as well
In my research for an answer i have found that it could be the daughter-board with charging or it could be the charging coil and antenna assembly on the back of the phone.
Has anyone else had any luck with replacing the charging coils after this type of error ?
