celluniversal · 06-04-2006, 04:37

NOKIA 3100 working fine but some times network gone(no network bars) then after some hours network comes automatically(without doing anything)
This will repeat atleast 2 or 3 times in one day

I reballed the hagar ic result working fine for somedays without any problem then after a few days same problem repeated.

I made full erase and flashed the phone with 6.11 version but no result same problem

I changed the hager ic too but no use same problem

ANYBODY HAVE SOLUTION????

Problem in Sim connector Or Sim IC. check that.........

when you dont have network in phone try to do manual network search in phone and check what is the msg you are getting it is no network found or no access
if no network found mean RX problem
if no access mean TX problem
based on this you can solve your problem

dont make stupid things (hardware repair). first write a good pm, mostly the problem is due to pm(tested by me many times)

Tulga · 06-04-2006, 18:47

1. write good pm
2. Replace 32khz crystall clock
3. Reball hagar
4. Reball UEM
5. Reball Upp
