Have a 8310 with a strange problem. It can power up normally, but in a secs the led off and the keypad locked. If I unlock the keypad it can work for a secs and got network, but then sometimes it restart by itself or power off. The phone had 5.11 firmware. I tried full flash it (mcu+ppm) with 5.57, but still had the same problem. Any suggest anyone ?

thx in advance
