Hi Guys,
Here i am again.
I have a GT-P1000 (GSM) Iīve been used CM9 from two years and a few days ago upgrade to CM11.
To do that i upgrade in a first step to CM10.2. I put the rom in SDcard and install it. make a second install to confirm the new partition as demand.
When i configure the 10.2 (just for fun) i already detect that gsm function donīt work, it is available but donīt detect my gsm card.
Well since the objective is the CM11 i proceed to the CM11 instalation... everything works ok during instalation but no GSM.

So,i rool back to CM9 from my original backup and after two instalations (because of the partiton) everything works fine include my gsm (so no problems with my card slot).

Do it again, first the CM10.2 and after CM11 (no gsm card insert this time) same problem, donīt recognise gsm card.
Anyone can give me a clue how to fix it ?

Best Regards,
Telmo Mac

You should be checking your baseband and IMEI.
If those are screwed up after you flash CM11, then likely you have a corrupted /efs

It is just a folder.
But it is encrypted file system, hence EFS.

When you use odin to flash stock GB rom, your EFS should be repaired by itself.
From there flash CWM kernel and have a go again at cm11. Usually that fixed the issue.
