I have been a happy user of CM11 on Xperia Z1. Then one day CM12 update surfaced and I happily flashed cm12 on xperia z1 c6903, for few days it worked fine but one day phone suddenly restarted and stuck in boot loop (I think around 28-dec-14). I flashed CM12 again but same issue, then I flashed older version of CM12 , phone started but SIM card was not detected. Then i tried everything from flashing CM11 snapshot, CM12 latest nightly, flashing stock ROM(all .157, .108 and other), but all failed. Now phone is not detecting SIM card. It is also showing baseband "Unknown". Somewhere someone has suggested that i need to install modem again, but i could not find any modem file to flash. I have tried everything, now only Sony itself can help me.
Thanks Ashish
