Hi All

Been asked to look at a dead 5210 for a mate that wont turn on. Ive done a little hunting on here and tried reflashing with knok (phenoix) but it wont read the phone at any level, same with rollis 478b. So I assume its hardware! can anyone give me any things I can check/repair my self on this phone, ive got a T6 and soldering iron at the ready

cheers
