Good day to all Symbian enthusiasts out there,

Please help me for this 3650 I'm repairing is not
functioning well.

Could this be a hardware problem? by the way
my friend tols me, it fell hard, then lost its power.

I was able to power it up by flashing it using griffin.

Sounds like at least a soldering job, or if not possible, a SIM card holder replacement or in the worst case the whole PCB needs to be replaced.

I have the same problem, only my occured after the mobile phone was returned from flashing in authorized nokia service. They do not have any idea why it happens. But i found a way how to temporary solve the problem. Turn the mobile phone off, plug it into baterry charger and then turn it on. that should do!
P.S try to replace your SIM card with someons elses, message should not appear. At least in my case it didnt.
