guys, need help..a friend of mine recently bought her phone...she tested at the shop, and the phone turns on without problem, so she take it to skin, etc etc, the phone died due to lack of battery..

so she went home, charge the phone, and try to turn on..she says that the phone vibrates, she gets the white background nokia logo screen, but then after 10 seconds or so, the phone is turned off again...

do anyone know what could cause this problem?

basic laminate kinda of skin, like those shop in lowyat do one...hers is just basic transparent skin...
i already ask her to perform a hardreset, doesnt seem to work...and the other day she was saying the whole phone suddenly heat up for no reason...so i guess the phone must have been turned on but somehow not functioning...i'll already ask her to send back to the shop and ask them to flash or something..

thanks for your help ya...
