Need Nokia 3110C Low Network Solution..


Hello Friends,

Can anyone give me the correct approach of solving the LOW NETWORK problem in Nokia 3110C set.

I have thoroughly washed the set with best quality thinner and dried it out with SMD REWORK STATION.

Blew hot air with amtech gel on the PA/PFO, HAGAR, UEM (RETU) etc.

Fully erased the software with MX-KEY and reflashed it with the latest version and wrote the 100% Ok PM file also.

THE NETWORK BAR OF VODAFONE SHOWING MAX. 3 STICKS and then going down to onely 1 stick and sometimes going off completely.

What else I could do now?

Need an expert opinion.

Advance thanks to all,
