Hi guys. I had my phone working properly this morning, and then all of a sudden I got the generic IMEI (0049 etc). No apparent reason at all. I tried restarting my phone several times but nothing helped.
First I tried doing the 9 steps described on this thread, since I had a backup of the original EFS folder on my sdcard (the files were dated from 27/07/2011, which is exactly when I got my SGSII), but after step 9 and rebooting the phone I got the welcome to android screens as if I was booting the phone for the first time, but still had the generic IMEI.
Maybe worth mentioning as some others I didn't have the ".nv_data.bin" file, only the ".nv_data.bak" file both on my original efs folder and the backed up one.
After that, I tried using Galaxy SII Repair app but it didn't change anything either.
Then I found the tutorial on this post (http://forum.xda-developers.com/show...7#post39100837
), which I tried doing both from terminal app available on Market and from the adb on my PC. Through terminal I couldn't do all the steps, but from my PC I could (I had to force a recovery reboot to do some steps, though). I finished doing all the steps, but even like that nothing changed.
My current status is I have the generic IMEI (0049...), I can access the 3G mobile network, but status shows as "emergency calls only" and when I try to call some number a message on the screen appears saying I'm not registered on the network.
I have gone through all possibilities I have read and none made my IMEI return to its original state
Any help would be gladly appreciated.
