5300 strange problem
 

hi everybody

i have a 5300 that seems to be dead not powering neither charging but sometimes after several attempts to switch it on, it turns on up to nokia logo then turn off and sometimes it powers on normally and works perfectly and after u turn it off it is dead again.
i tryed to flash it with jaf usb dead but i got error init usb flashing.
i didnt try with fbus i dont have the cable
can someone tell me if it is sotware problem or hardware and if so in what part is the problem ?
thanx to all helpers

I Think Its Hardware Problem................

trhgis is a hardware problem check supply on battery connecter

check theboard maybee board fall down & check all ic which ic bistarbd thats solved

;););)Hardware Problem................

that is hardware bro... try to reheat flash ic... I already did one like that...

yes, bro..it needs to be hardware repair..like flash ic its maybe lost contact..

it's a hardware problem, you have to check the IC's and when it turn on try to touch the board you will find one IC that will be burning you can fell it's temperature, 90% the power IC, try to clean it, reheate and/or change ;)

thank you for all helpers

i hheated all ic's but in vain i tryed to twist the board to see it it could turn on but nothing now it's complitly dead i cant power it at all!!
i tryed to check it with jaf fbus this is the result :
