I have heard about this EFS and how things get Nasty when IMEI gets corrupt in samsung phones . So Can anybody write a simple steps for me to backing up EFS and restoring it if ever necessary ?
Thank you .
Another thing i have forgot to mention is i am unable to find a Folder called EFS in my / . There is a Folder called Factory which has all ther NV data files.
Hi, my N7105 has lost the capability of reading its IMEI (and even knowing what model it is) after I flashed this: http://forum.xda-developers.com/showthread.php?t=2531965
I have an EFS backup, but it's useless, it seems that I need the param_bin for the N7105, because as I've read, the phone didn't really lost its IMEI, it only can't access it. Please help me!
Solved. Just flashed the via Odin the .bin files that were inside the .tar.gz backup made with EFS Pro, then the IMEI, model number and signal got back. Then EFS Pro was able to recognize my phone and restored the full backup, now even the serial number is restored. Hope this helps anyone who finds himself in a similar situation.
I am in a the same situation, but my efs backup is just a efs.img created by efs_backup_restore_win.
Restoring using it can't bring back my imei.
[Edit] EFS pro keep saying Device not connected. But I already granted the ADB connection in my phone.
I have an AT&T S3 which, during some shenanigans I don't remember, was encrypted with a password I could not retrieve. I used Odin to erase the phone's NAND because I had a nandroid backup. This backup, however, was corrupted. I was able to use Odin to flash a stock firmware, but I now only have access to EDGE instead of LTE.
I have restored EFS and NV backups from another AT&T S3 with my IMEI and serial written to them, and my serial and IMEI display correctly in my phone's status window.
I have tried flashing every available modem for the phone.
I have tried numerous APN settings and *#*#INFO*#*# settings.
I have tried damn near every solution to similar problems in this forum.
Any more ideas?
Where did you get your EFS and NV, and how did you restore them?

I used EFS Pro + Qualcomm tools to backup the EFS folder and NV data from a working AT&T S3. Doing this brought back my IMEI, but did not much else otherwise.
EDIT: To clarify, I used the tools to write my specific imei and serial to the backup before restoring that to my phone.
Ok, a lot of these usually don't get fixed, but I'm going to stick to here what worked for some.
First, I'm going to assume that you injected your IMEI correctly. I would next use the EFS Pro to format your EFS from the restore option at the top (then clicking format EFS), since that EFS came from another phone. Your EFS folder will automatically be re-created when you later reboot.
Next, I would download and unzip the attached file. Inject the .txt file with the nv reader /writer. The nv reader writer can be found in this thread.

Follow steps 1-4, but instead of reading, you're writing the .txt file that you unzipped to your NV. It only contains missing information and should not touch your IMEI. Do not change the dec or hex range.
Reboot the phone and see what happens.
I've lost my phone but I still have my efs.img backup. Is there any way I can extract my IMEI number from it? Thanks.
I just lost my whole efs partition without any backups, now it won't register any sim card or network at all, could someone send me a backup of efs.img or qualcomm qpst qcn file? ([email protected])Thanks a lot.
twrp backup or tools backup all fine
