Hi, I'm wondering If anyone can help me with a strange issue I'm having with my Vibrant. I unlocked my phone a while back using the method in this forum
http://www.communityhosting.net/sgsunlock/vibrant.html and it worked fine.
Then I installed custom roms, I first had a froyo rom and then most recently used Eugene's Gingerclone. However a couple days ago I went to look at my phone and the APN settings were all jacked up (There was no signal just a cancel sign where the bars used to be). I've went back to the stock 2.1 rom- T959UVJFD using Odin and the service works, however when I upgrade to any other ROM the APN issue remains and I have no network service at all with any rom I've tried. I really don't know what the issue is...if anyone could help I would greatly appreciate it...because I would hate to be stuck with the stock ROM. If you have a paypal account we can work something out. I am using AT&T sim card with T-Mobile Vibrant.Thanks
Hi,
When you go to Settings > About Phone > Status...
Does your IMEI read correctly? Or do you have a generic number that starts with 044xxxxxxx or something like that?
It appears to be a generic 0044 # under the stock rom. Thanks!

No problem. Please download and install Root Explorer (cost money but worth it) and browse to your EFS folder. When you are there post up the files in that directory. This may be correctable as your unlock wasn't fully successful.
EFS Folder
.android
.imei
.nv2.bak
.nv_data.bak
.nv_data.bak.md5
.nv_state
nv
nv_data.bin

First, copy the full EFS folder somewhere else on the phone like the Internal SD storage section or to your PC. Now, delete nv_data.bin and nv_data.bin.md5. After those are deleted, copy .nv_data.bak and .nv_data.bak.mdf. After they are copied paste them in the same EFS directory and rename them to nv_data.bin and nv_data.bin.md5. Reboot the phone and let me know if you have your IMEI number back. This may re-lock the phone but atleast you have an intact IMEI number. Then copy the EFS structure in full valid form to somewhere else on the phone or PC and now you can mess up that section as much as you want trying to unlock and you can always restore the good folder and retry. Or if you want to send it to me, I can unlock and maintain a valid IMEI for you...
Nope, IMEI is still the same. The phone only creates a new nv_data.bin file and no nv_data.bin.md5 is created.
I stumbled upon your mobile tech video on Youtube(repairing the IMEI). After watching that, I'm pretty convinced my Vibrant's IMEI is lost forever. I'm just confused because the dates modified on the nv backup files are from last October (before I even tried unlocking or doing anything with the efs folder). I'm probably going to just put this phone on eBay. Thanks again for helping me figure this out.
Hello
I have a China Mobile galaxy gs3 i9308, and the imei no. was changed to 0000000000000/null because of rom flashing (I think).
Now I am not registered on the network, so I have to change the imei no. back.
I tried several tutorials online, but seems like they're only for the galaxy s.
I tried the 9 step guide but I can't find the .nv_data file in my efs folder.
Can anyone help me or point me in the right direction?
Thank you

Thanks for the quick reply. But I followed the written version of the guide and it only works for galaxy s? Because in my nv_data.bin file there's no line 00188008 in hex editor.
this is the link to that thread: http://forum.xda-developers.com/showthread.php?t=881162
The video poster also said it only worked for galaxy s.
Any other ideas?
hey, I have the same problem, SGS3 with wrong imei 0049.... i lose my efs file, someone can help us?
You could try flashing stock rom, heard that this sometimes restores imei, not sure if it works on s3
Also, check if the rom or kernel you flashed created a eggs backup, some do

Please help
i have the same problem i cant fix my imei, after flashing the phone it changed to 00499.. it made no backups and no nv_data.bin.bak
If the efs folder havent been backed up, what can i do? I tried changing the nv_data file like some tutorials here explain, but no luck(tried couple of times, it defently not compatible with my galaxy s3), i believe these tutorials are for erlier galaxies.
Please help!

Did you back up the efs folder before you flash your device?
I understood that imei numbers were hardwired into the phone. And changing them n having the equipment was illegal. This is what the networks use to bar your phone if it gets stolen.

How to restore your IMEI number on SGS3 (GT-i9300)
I deleted my IMEI number when flashing roms a few days ago and it was showing as 000000...
I searched everywhere for a recipe of how to restore it and could not find one that would work. The closest that I got was a brilliant post (see link below) describing how to restore the IMEI on a SGS2 i9100. After following this recipe, I was able to restore my IMEI number to 0049 .... which is just as useless as 0000....
It took me a couple of days of research (and HUGE thanks to everybody whose previous research I was able to use) and I finally succeeded in restoring my IMEI using the 9 step process that I describe below. I can't guarantee that it will work and I do not know if it will work on any device besides the SGS3 GT-i9300 (international SGS3), because this is the only device that I have and was able to test the process on.

Restore IMEI on SGS2: http://forum.xda-developers.com/showthread.php?t=1264021
Download EFS PRO: http://forum.xda-developers.com/showthread.php?t=1308546
Download your original firmware using check fus downloader (http://forum.xda-developers.com/showthread.php?t=1032437&page=18)
You need:
-EFS PRO, a brilliant little program for Windows used to backup / restore the efs folder as well as recover / repair the nv_data*.bin files.
-Windows
-Windows USB drivers
-Rooted SGS3
-Root explorer.apk
-Original phone firmware (actually, you only need the modem.bin file, so once you download your firmware package, you can just extract the modem.bin file).
-Odin or Heimdall
Your phone's IMEI number is stored in the ".nv_data" file in the original shipped efs folder.
Process:
1. make a copy of your EFS folder using root explorer and store it somewhere safe (on your SD card and external SD card should do it).
2. delete the EFS folder from the root of your phone using root explorer.
3. reboot the phone
4. open root explorer and go to the EFS folder (yes, it is still there! The Android OS has generated a new one for us) and delete the following files:
nv_data.bin
nv_data.bin.md5
nv.log
.nv_data.bak
.nv_data.bak.md5
nv_data.bin.bak
and the entire IMEI folder.5.Now go to your backed up EFS folder on your sd card and copy the IMEI folder and the " .nv_data" file (note the dot) to your new EFS folder.
6.Make another copy of the ".nv_data" file in your new EFS folder. Rename one of them to "nv_data.bin" and the other one to "nv_data.bin.bak".
7. Connect your phone to your PC and start up EFS PRO. After your phone has been detected, press the "Repair nv data" button to correct the ownership and permissions.
8. Reboot your phone into recovery mode using the three botton combo and flash the original modem firmware (the modem.bin file that you extracted earlier) to your phone using Odin (use the "phone" button for the upload) or Heimdall (use the "radio" partition for the modem.bin file upload).
9. Reboot the phone normally and your IMEI number will be restored and you will be able to connect to your mobile network again
Good luck and let me know how it goes

Hi there
You need YOUR IMEI number back (which is not 00000... or 0049...) it is the one under your battery.
If you followed all the steps, then it should have worked.
One extra thing that you can try is if you did not flash your original phone firmware (and you only flashed the original modem.bin file) then do this step first.
And then work through the 9 step process, ignoring the step where you flash your original firmware (because you will have already done it).
Good luck and let me know when it works

Good news is that it will work - even if you did not back up your efs folder before you messed with it!

Hi,
after flashing a modem, i got a "fake imei", and i can't connect to my provider.
After some search i found a thread to recover:
- copy esf to sd
- format efs
- restart
- copy imei folder and nv_data.bin.bak (from 2010) to nv_data.bin
- restart
i'm still stuck with this imei.
Is there something else to do ?
i tested this process with android 4 samsung, and 2.3.5
do i have to be in the same release than first time i used the phose ? (2.3.3)
thanks for advises/help.

Hello,
Thanks for your suggestion,
i tryed that yesterday, but as i have no backup how can this solve the problem ?
should i rename something ?
i did the few steps to format and reinstall. but it still the same.
I noticed after flashing the modem, the timestamp changed from 2010 to 2013 on the file nv_data.bin and .md5
i had a .nv_data.bak from 2010 is this the correct one ? (in the efs folder)
this is the one i'm trying to restore, if possible/correct ?

If you tried SGII_Repair I assume you've already tried this and didn't work, right?
If so, try going back to previous MODEM (back EFS folder with HC kTool first).

Okay, so you've got 2 EFS folders, one in your SD card and the other one in system's folder, all same files in each folder, am I right?
the copy i have is a backup i did after the problem.
not sure at this time, i'm thinking to restart fresh, i'll copy /sdcard/efs to /efs and replace.
Then i'll try again gs2_repair to see if i missed something.
Woot working get my imei back and online
many thanks !!!!

Hi guys !
I installed CM13 in my phone just that I did not back up EFS folder where is the IMEI number, and now he is at 0 and this folder does not exist
I've tried restoring anyway and no method I tried worked
Could anyone help me with this?
Without this IMEI number I can not signal my mobile operator
ps: I have 2 annotated IMEI numbers, but do not have the EFS folder
My device is D618
Edit:
If anyone can provide this folder for me I will be grateful (I will not use your IMEI number)
Currently I had damage a new phone in the process of transferring a twrp backup from my gold note 8 onto my black note 8, but now silly of me I didn't realize I tried restoring the efs partition as well causing me to have a bad partition. Now, I currently manage to fix the efs partition and solve some issues im just stuck in trying to find the file in which I can alter the IMEI as currently its 00000000000 i've checked NV_data, but I cant seem to find the offset that contains it i've tried searching it on my working phone to see if I can spot the imei so I can find the right offset, but no dice.
edit: I've solved my problem i'm not sure if it'll work for you, but what I did was root my device, delete the efs folder which eventually game "000000000" imei and the baseband wasn't appearing as unknown anymore, then within the new efs folder that was created on its own there was a folder called efsec in which it contained !svc and svc files, so I extracted these files and edit these files with notepad++ which within there was an option for imei and it showed me all 0000000 so I imputed the original imei, and finally after a reboot I reflashed stock and then flashed a combination file which when it booted up it automatically restored my imei

edit: I've solved my problem i'm not sure if it'll work for you, but what I did was root my device, delete the efs folder which eventually game "000000000" imei and the baseband wasn't appearing as unknown anymore, then within the new efs folder that was created on its own there was a folder called efsec in which it contained !svc and svc files, so I extracted these files and edit these files with notepad++ which within there was an option for imei and it showed me all 0000000 so I imputed the original imei, and finally after a reboot I reflashed stock and then flashed a combination file which when it booted up it automatically restored my imei

Thanks for the answer. I would like to clarify one point ...
I realized that you replaced the parameter "deviceID": "00000000000" in SVC and !SVC files (in the newly created /efs/ sec_efs folder) with your original IMEI.
But what does "and then flashed a combination file" mean?
With which software did you flashed the modified SVC and !SVC files?
Maybe you just replaced SVC and !SVC files with 00000000000 IMEI onto SVC and !SVC with your original IMEI via RootExplorer for ex.?
