| Hi,
Basically network problems are hard to be solved. why is that ? they are connected to so many items maybe over 200 items ! (Coils,caps ics ....) anyway just to recap you may do the following (if you are lucky it will work):
1-replace antenna
2-re heat BB_CPU
3-re heat network parts
4-You maybe unhappy if you spend all your time in testing all the parts ! ! ! I would repair 150 phone for one phone that have network problem that is my own opinion
wish you the best of LUCK ! |
