I did an update for ICS 4.0.4.
Everything was ok.
But after 3 weeks using this rom, I did a factory reset (*2767*3855#) and now my Gnote (GT-N7000) dont recognize any sim card.
I think this is not a problem related with IMEI. The IMEI number on the stiker in the back is the same when I put *#06# or access via menu.
Now in the notification bar appear "No SIM - Insert SIM Card"
What I've done:
Check if simcard is not inverted (no, it is not)
Try my simcard in another phone (yes, this works)
Try another simcard in my phone (not work)
Do the factory reset again (not work)
Put the 4.0.4 rom again via ODIN (not work)
Upgrade to 4.1.2 via ODIN (not work)
Downgrade to 2.3.6 (not work)
Upgrade to 4.0.4 via Kies (not work)
Please, I need help to solve this problem!
Sorry about my english.
Thanks in advance,
