Guys, i need some help from you guys...i have messed up my E970 phone's network.
Actually, i messed up with its EFS parititon and now i am not getting any network in my phone. My phone is ON, everything working but it is not detecting any sim
i read on XDA forum and got that i need to replace my EFS paritions again with system actual EFS partition file.
Any user friend who has E970 and who is rooted, pls download below file and run in recovery to back up the phone's EFS parition, then pls mail me that backed up EFS parition file so that i can replace it to run my sim card:
http://dl.xda-developers.com/attach.../8/4/9/9/Optimus_G_Create_Flashable_EFSv4.zip
pls download, its only 1 MB file and it will create a single file of small size (in KBs), that file will be placed in /sd card/ EFS_backup
pls mail me that file to save my phone...pls help ppl...it will not take much of your time...help
I am under the impression (perhaps mistaken) that EFS partition contains IMEI data. If so, that is something that no one should be giving to another user.

It does. Giving that file to the OP will result with 2 phones with the same imei. To OP: sorry man you are asking for too much.

I suggest asking him if his offer to make a ZERO EFS zip for e970 still stands. If so I am willing to send him my backup if needed.

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
nv_data.bin.md5

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.
hi
was reading a lot about corrupted efs folder and how to backup it.
just a few questions for my personal interest:
is this efs folder restored/replaced,new written when flashing a new stock rom?
if not,is it installed from samsung and ment never to be changed?
if so,how is IMEI generated,or simply written inside a binary?
How does a service repair the missing IMEI,if corrupted?
i flashed a stock rom via odin,but different country code on my SG2,all went fine,still have correct IMEI.But does this flashing change anything within that efs folder?
thanks

No. However some people say that the efs folder is written to on every boot, so there's always a small risk that it gets damaged.

Yes, exactly.

I guess Samsung could answer this question much better. From what I know: They encrypt the IMEI and write that bin file to the efs folder. So in theory, if you knew the encryption algorithm you could do that, too.

I assume that Samsung can simply encrypt the IMEI again and rebuild the directory.

My s3 stopped recognizing the Sim yesterday, so i searched for a solution. i read in xda that its the EFS partition. I got no IMEI and no Baseband. Somehow i found 2 files on the internal SD Card: "efsbackup.tar" and "efsdev-mmcblk0p3.img".
I read this thread, but it didnt help me.
Any idea how i could fix it?
Btw, Android Revolution HD 11.0 with stock kernel
I'm guessing your Rom auto backs up the efs, so best to ask on their thread about reinstalling it
Restore your EFS backup .
jje
im going to install now arhd 11.3 and then do the restore of the efs backup.
i noticed that the backup was built yesterday evening, when the problem already was. well it seems like i got no backup, when it was working
I followed in this thread this post:
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

and now i got an IMEI, but its still not mine: 004999010640000 / 01
If you have an efs.tar file why dont you put it in PDA in Odin?.
wont work.
deleted
Ok....then I dont understand why it backs up as a tar file then
yesterday i flashed siyah kernel, siyah probably made a efs backup. but that backup was already after that problem happened.
well i got now the 0049 imei
So you dont have a back up of you original IMEI is that what your saying?.Flashing ROMs normally is what makes a backup not flashing a kernel so Id say the backup is original.

you need to read better then
You'll need to perform an "IMEI injection" which is a kludgy last-resort restore method that manually writes the IMEI to NVRAM; the link I provided in Part C of "Backup" will tell you how to do it.

That's what the efs backup is for xD
Calm down, or you'll make things worse. Unzip the efs.tar to /efs and reboot your phone (DON'T PULL THE BATTERY)
Everything should work like a charm again
Hope I could help!

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.

No EFS back up? always back up EFS folder.
Try GSII_Repair.

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).

Not the original ROM, the last modem you used before flashing the one that got you in this mess.

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 !!!!

Hello everyone!
My NX507J, after partitioning procedure and some my mistake, has lost IMEI, IMEI2 and MEID. :crying:
I haven't got nv backup, so, I don't know how to do!
Is it possible to use a nv backup from an other NX507J and restore my phone with it changing the IMEI code with a qcn file reader??
So, if it is possible, does someone have got it for me? :angel:
Thanks in advance

I have the same problem after using cwm 12, i played around with the build.prop and it went into a boot loop, i took it to an expert to put a brand new imei on it, after it is done ill ask exactly what he did and inform you too.

Do you have the "Nubia Backup" folder in your root directory (from when you did the update) ?. If you do its possible in fact easy to recover.
Cheers

Did you resolve? I have the same problem.. There aren't backups..
Hey,
I have the same problem and I cannot restore my settings. In fact my sim card is not recognized and I have no network.
I have the c://nubia backup folder that has zip files inside. In the zip there is an nv.qcn , bluetooth.txt wlan.txt 1.persist etc
What should I do in order to restore my imei? I have tried with the nubia updater by pressing on the icon and although it says succesful and the phone reboots it's in the same condition. When I try with nubia tool studio i can only choose a folder and not a file. So I have tried by extracting in a folder and connecting it there buts says no xml file found.
Also, do you think it has to do with a different rom on phone than the one that the backup had been made?
