It is probably SW problem. Maybe it is 3330, or 3310 upgraded to 3315? Flash it wit full flash (eeprom included) and with Rolis flasher. Try to set it to 3310 and 3330. If it reports "incorect phone model", just continue with flashing.

If it still doesn't work it may be problem with RAM, flash or MAD.

@B21Playa:
Phone RAM is BAD means:
FIRST OF ALL (The data shifted through CPU to RAM ,that is responsable for comunication) is not responding.
1. Phone's RAM realy bad.
2. System ASIC doesn't respond corectly for a Boot Sequance.
3. System ASIC doesn't respond at all.
4. Posibly EEPROM is demaged.

Possible reasons:
Empty Battery.
Bad contacts.
Dead MAD.
Dead RAM.

it isnt easy...you have to take it off the pcb...clean pcb and chip then solder new balls on to it and solder back again...
