network signal???

---

a week ago i installed Incubus26jc's Super Froyo rls14 nand method, i hav panel 1 pola100, everything was ok... only three things were not working:
1) camera( always show green color)
2)battery( always show 100%)
3)network( my phone does not catch network signal)

so i decided to switch back to windows, i tried almost all the 6.5.x rom's, but the network or signal problem does not get solved even after the installation of "Radio_Murata_PPAS_1.58.21.23". sometimes i can do messages, but voice call...no way, if the call gets connected then the other person on the call and myself cannot listen the voice of each other???

then i thought to install original wm6.0, but same problem arise, so i again install "Radio_Murata_PPAS_1.58.21.23" on wm6.0 and the problem gets solved. but not in wm6.5.x.

help guys what to do???
its a request that plz give the link, if any software need to install to solve the problem.
