I recently rooted my Samsung Galaxy S2 AT&T phone (SGH-I777) with KitKat AOCP version. I used ClockworkMod 188.8.131.52 recovery. However, I encountered a problem "E: Cant mount storage/sdcard0" . I formatted my sdcard0 and then it worked.
However, in this process I deleted my efs folder which supposed to have the IMEI information. Hence, now the phone can not get telephone service, so I can not call.
I have gone through the forums explaining how to restore IMEI if you have a backup, or how to edit a corrupted imei file. However, I coudn't find a suitable solution for my case.I don't have anything inside my efs folder to start with.
I know my EMEI number, since its written on the back of my phone. Is there any way I can generate a fresh IMEI file for my phone from the number. What steps I need to follow to get my phone running again.
Thanks for help.
