Nokia 6300 won't boot up

Hi manjit,
if u r using Nokia 6300, u must be knowing that its a symbian S40 series.. it wont stop workin in any condition except if the software gets crashed. so if the blue light is flashing when u plug it on charging and then goes away, that means the most basic IC of phone used to control every feature is crashed. Fixing that IC will need u to flash it once. The Repairman's sayin right, but if u still doubt on it, i'll suggest u to go to Nokia Priority Care & ask them to fix it.
Thanks

Manjit, If the phone is not booting and goes only halfway then the firmware may be corrupt. Go to Nokia Care and get the firmware reinstalled. Will thake them half an hour. You can do it yourself too, but that is risky. Nokia Care have installed a box between the phone and the PC. The box downloads the firmware and only if it has been downloaded correctly, it sends it to the phone. And the whole firmware is changed. I f you do it yourself then you could even loose your phone like I lost my E61i. The internet connection misbehaved and I lost my phone.

where can i buy a 6300 on off switch?
