SIM not working

Hi all, yesterday I flashed .101 using Flashtool (from .222) but the Flashtool binaries were corrupted and something went wrong and got bootloop. Today I used a different PC and at least it has been possible to install a custom ROM (.222) but the network is not working now. The PIN is requested but sometimes it fails and sometimes it just accept the PIN but there is no network. WiFi works fine. I have used this Xperia for more than a year and working well. My device is C6603 bootloader locked.
Thank you!
