Rasta, how could he switch on his 8310 and connect it to LM ??
The mobile asks the sec-code when he presses the power button...
I had the same problem with my sister"s 6210:
I used my self-made M/F bus cable and NokiaTool v1.8 by Rolis.
Switched off the phone, connected to serail port via M-bus cable,
power on the phone and press the "READ" button after 1-2 secs
and u have all the info for the mobile..."IMEI", "Sec-code" etc
Good luck.
