Hi,
I have a GT-I9100 SG II with no efs folder backed up.
I flashed the ROM once. however the IMEI has now changed to generic 00499.
When checked there is no .nv_data file present in the efs folder. Nor there is a nv_data.bin.bak file present for restoration.
I also tried to go on the stock firmware and re-rooted the phone, however still same IMEI number.
All functions work well. even I am able to make calls and receive it.
However somewhere I checked that normally nv_data.bin.md5 is used to verify the checksum of nv_data.bin and dump all the information in nv.log files.
When I check the nv.log files, it says
MD5 is turned on.
checksum fail
NV restored.
Does it have to do anything with thing generic IMEI 00499. Is there any way I can restore original IMEI for the phone (without a .bak file or .nv_data file).
Please help
No EFS backup = service centre or local mobile repair shop. Bit hard to restore something you don't have a backup of, dontcha think ?

Yes but what's the guarantee that they won't mess up more.
Do they have any tool to create EFS folder...
To avoid further more issues, thought of taking guidance from senior folks here..
Any advice???
You mean what's the guarantee they won't mess the phone up more than you already have ?
Samsung service centres have equipment to 're-write' the IMEI to the device, and local mobile repair shops who aren't service centres might also have this equipment.

My previous phone was Galaxy Spica and it has an efs folder where the nv_data.bin is located and supposed to have your IMEI among other things. I tried to look for an efs folder on our mediapad and I did not see any. Is there any way we can make a backup of our IMEI so we can restore later in case of a bad flash?
I have a feeling the IMEI is fundamentally hard-coded. I accidentally mangled my IMEI when I reflashed the modem_st1 and modem_st2 partitions, but when I re-ran a full Huawei update via dload directory it restored my proper IMEI back.
It is good to know that we are protected in some way. Thanks for the info. One of the worse cases is losing your IMEI and not have any way to fix it.
I installed a custom rom on my galaxy S2 and its IMEI changed to: 00499901064000 :crying:
I tried to fix it, so I rooted my phone and created a back up from efs folder then deleted it, so madly I lost the back up of the efs folder.
After I restarted my phone it created another efs folder (it had to create it) but I lost the real efs folder.
Now is there any way to recover my IMEI?
it had lock screen problem with ICS but I repaired it (created the file "keystr" in IMEI folder and wrote "ON") :victory:
Without a known good EFS backup (I.E one that was made when your IMEI was correct), you pretty much have two options. One, Samsung service centre/authorised repairer. Two, contact Odia via PM (and wait patiently for him to respond. If you hound him he'll probably ignore you), he can sometimes recover EFS/IMEI (for a small donation; much cheaper than paying Samsung to fix it).
Actually, I tell a lie. There might be a 3rd option. Maybe a local mobile repair shop might be able to fix it. You're only going to know that if you go to one/call one & tell them what's wrong. They may/may not have the same gear as Samsung & may/may not be able to fix it.
Hello all!
This is my first post, and now I need your help.
I have a Galaxy SIII, but he is having trouble functioning as a phone. Says I'm unsigned.
Finding enough on the internet, I discovered that the problem is the IMEI.
The IMEI appears on the phone's settings is not the same as that described in the label behind the cell.
Searching further, I saw that it would be necessary to backup the EFS folder, but I can not find this folder, already tried all the ways it seeks, even with apps that do this but they are also not there.
Somehow, this folder has been deleted from my device.
And now, what should I do?
Is there a generic folder that can be used to retrieve the IMEI?
Please ask your help because I am very frustrated with this.

To late .
EFS folder is used to restore IMEI from a backup of your EFS .
Return phone to the seller or take to a service centre for repair .
Wrong IMEI can be stolen phone user flashing firmware or phone failure .
Try a factory reset first .

I tried the factory reset, but it did not work.
Is not there any way to do this?
just restore the efs backup you've made. if you didn't, try restoring any nandroid backups, maybe they have efs included. if that doesn't work, try looking in the sdcard for some files that have "efs" in the name, some kernels back it up automatically. use adb to view the files (Google it). if that doesn't work, try flashing a stock rom and factory resetting from recovery.
and that is absolutely everything you can do.
I have bought a galaxy s3.
Old owner has deleted efs folder while he was trying to install a rom. he had also no efs backup.
How can i put it back? i have my phones imei but imei shows null/null.
Return it for a refund, there are some solutions for efs problems here in q&a but they probably won't help your situation.
Likewise no EFS no phone .
You can search and read all the multiple lost EFS posts .
Guess the seller new that EFS is not replaceable .
Possible a service centre may repair if you have the IMEI and an original sales receipt.

I´ve rooted my s3 and now is my IMEI 004999010640000/01 and after that it is not possible to make calls,. I´ve read a lot of pages about restoring IMEI by EFS back up I have, but nothing still work. Can somebody help me??
EFS back up was created after rooting so maybe that the reason, why I cannot restore (restoring works but with false data of IMEI, is it write??) So have can I put my IMEI back without back up??
Thank you
Factory reset flash stock rom that fails it is a service centre repair.
The efs backup is in tar or tar.gz format ? If yes just unpack it using 7zip and copy paste efs folder contents from backup to phone efs folder ....
sent from the state where marijuana is NOT illegal !
You only rooted? Is that the FULL story? How did you root?
