Im also having network issue before. When i flash rammar PA 4.6. I ask everywhere and the answer is yes should flash the baseband. But i found it hard to update though (with artas method, or flashing the kdz). And i dont really know why.
At first i almost desperate about that, and decided not using CM 11 version or up just use CM 10. And then i found master Imer thread. Since it was the same model (P765), i then decided to try flashing newer rom again.
After flashing, the network issue still come. And then i read again carefully the requirement for the rom. I found that my recovery still using CWM 6.0.4.8, i try to change the recovery to TWRP suggested. After flashing recovery, and the rom. The network issue seems fixed, just one or two time my device lost signal, but not long it back again without reboot the phone.
So i may think its not always because baseband, maybe other like recovery.. But its just my tought, i may wrong too.. Anyone?
Sorry for my bad english and the long story, just sharing
