[Q] Problem: IMEI number, serial number, baseband, etc. unknown

view story

http://forum.xda-developers.com – Hello! I have a samsung galaxy SII that has lost all network connection (wifi works though). It's just a check of the pillars and cant either call or text. When you go in and check Baseband it says unknown. Similarly, IMEI, serial number and all network related stuff. I have searched and found EFS Pro but it did not work following the wizard. Is there anyone out there who can help me get my phone working again? Would appreciate any help very much! Im running CM9 stable by the way. (HowTos)
