I have recently searched for solutions in the S3 forum specific for my problem.
For some stupid reason I deleted my efs folder through recovery now i am unable to send texts and make phone calls. Going into the mobile network settings i can't register on the network. Now I don't have a back up of an efs folder with the files that it contained. So i am wondering if anyone knows of a way to make an imei file and a way to flash this into my efs folder so i can register back onto the network?
When i type *#06# it shows my imei so there must be another file(s) responsible for my phone being able to register on the network!!
Service centre is your only option without an efs backup.

I flashed my phone today and put on a new ROM and in doing so forgot to save a few files like Mobile Backup, and after clearing my SIM first my contacts are incomplete and I can't get them on my phone without mobile backup. Does anyone have a copy of it to share so I can put it back on my phone?
Thanks in advance. I've spent over an hour searching for this on here and have failed miserably. If you can think of anything else from the T-Mobile base ROM I need to put back on please share!
The thread below is a sticky at the top of this forum section, and in it you will find a link to all the stock items extracted from a T-Mobile HD2. One of them is the Mobile Backup app, and any others you decide you want will be there too.

Thanks a lot. I could not find it to save my life.
Galaxy Tab (P1000) with IMEI corrupt i dont have EFS backup as well
whats the best possible way to get original imei back?
Forget to add my EFS folder is completly empty no files in there atall
wbr
ok i have downloaded SUPERUSER from market place which can show me FILES inside EFS FOLDER what now?
anyone?
anyone can please post me fresh working BACKUP of EFS folder for GALAXY TAB
please
sorry, each efs is unique to each tab. basically your stuck with that strange imei but it should work without any problem and also the tab should unlocked now
In india the corrupt IMEI is blacklisted in every network so it cant register
i know each EFS is unique but i have seen no other way yet to fix IMEI back to original one in case you dont have a backup i really wanna do some experiments with some working EFS backup
Maybe it will result into solution please PM me the backup link if you feel uncomfortable in posting here please
If you don't have a backup you're screwed. In addition to each EFS being unique the IMEI is actually encrypted as well. Unfortunately I don't think anyone is going to be sending you their IMEI.
Hi,
seems like I've just noticed this issue, even if my last flashing (no, I didn't use that Odin option to clear efs) has been done 7 months ago.
The (italian) guide I have read when I bought the Spica back in June didn't mention ANYTHING regarding backing up the efs folder.
My IMEI is 00000000000000, but I can succesfully make and receive calls, sms, and use HSDPA data (Postemobile, a virtual operator working on Vodafone network).
My efs folder contains only a nv_data file.
My doubts are:
-If my IMEI is blank, why I haven't any problem at all?
-If I flash with ODIN a stock 2.1 firmware, can I recover the issue?
-I asked a friend a good nv_data file from an eastern Europe Spica, in an extreme case may I overwrite my nv_data file?
-Any hints regarding the policy of the US carriers if the IMEI is blank? It would be a problem if I couldn't connect to the mobile network. Last time ATT and T-Mobile worked well, but that was before the last ROM flashing, so I don't know...
thanks
Your nv_data file did get corrupted or deleted. This could happen if you ticked the option "Debug Only" -> "Phone EFS Clear" option in Odin.
When the file is broken or missing a new file is created at startup which does not contain IMEI data. Look if you have a nv_data.bak file in your efs folder. You can rename it and look if it fixes the fault. If there is no such file then you have a problem. This can't be fixed easily.
You can go to a professional unlock shop nearby and get a emei repair.
Ore you can contact this guy and get a fix for 20$:

PS: The missing imei will not cause problems with the phone. The complete phone will work without a problem.
Hi, everybody. A friend of mine is stuck with no wifi, so no mac address registered and no imei.
I need somone to check for if the file containing this info is nv_data.bin or .nv_data or anything like this because I can't any file close to this one. I found a method to restore from nothing but I need I think a file called nv.qcn. And I could manualy editing the file to add my own imei and mac address.
Can someone help me?
Nobody has qcn backup? Pleeeease!
You need to be careful with files like those. Have you tried a factory reset? Using MifFlash doesn't wipe data, if that's what you're worried about. It will probably be a good idea to backup to PC or microSD card, though.
After resetting and still no IMEI, I'll suggest this guide. It helped me restore mine when it accidentally got wiped a while back.
