hello i need help i´ve been trying to unblock my samsung vibrant but i cant find efs folder or nv_data.bin. what can i do. I don´t have a copy of this files i´m desesperate please help
Do you have root access and root explorer?
on the market look up galaxy S unlock. Not All vibrants had the nv_data file or whatever it is that allowed them to be unlocked in that way If I remember correctly. Galaxy S unlock has a generic unlock method for the Vibrants affected by this. I used it, it seemed to work. dunno, since I haven't tested it on any other SIM cards, but it did backup /efs to the SD card and create the files as it said it would.
Its worth a shot, and comes with a way to revert back if issues occur. Be sure to follow instructions, Don't delete the files it creates on the SD until you test everything out and make sure you have no issues. This way you can revert back using the backup.
same here
I try to get an unlock code using generate unlock window but after I ran it, it show error unable to find file <nv_data.bin>
Do I have to root it first b4 i can unlock it? please help.
thank you
Hello I seem to have the same issue...
I have rooted the phone, I have a file manager to browse my in-phone folders..
I went in the efs folder it says: "the folder is empty or have been banned. not the retrieved information"
I have also been trying to unlock the phone.. (i9000) I have tried all the ways that are on the xda developers and have finally tried to do it the manual way...
But I am stuck at transferring the nv_data.bin file...
Please help out!
Thanks
Im having the same issue. Been looking for an answer for hours and no luck. Im dying to use this phone...

i have the same isssue
Hello, The reason that you can not find the folder EFS it is because it is hidden. You can install Android Terminal Emulator from market
And then run it and write the command to see all the folder
ls -l
You will see the EFS folder.
Please let me know if it works for you

Hi, I am new this forum and new to using a smart phone, I have my vibrant(used) for about a week now. I try to unlock it for ATT. I read through several dozens threads on this forum about unlocking the vibrant phone. I got all the necessary software install on to the pc(atleast i think so) such as sdk, java,adb, generate unlock window, etc, i also install root and superuser on to the phone. THE PROBLEM IS my orginal IMEI has change after using some unknown unlock software to unlock the phone, it ended up changing my IMEI, it stated my IMEI was change after it was done (now i learn my lesson of not to use untrusted software for phone). I try to do a factory data reset which didn't work.
How do I copy my backup efs folder into my vibrant efs folder?
I try to mv it through adb shell but it stated "read only", show how do move/copy/write my original efs folder files in to the one on the phone ?
And the reason I used a unknown unlock software is because all your methods on the forum did not work for me. Generate unlock window did not work for me, and I try one of the other users method of copying bml3 files and execute it with sgux on window cmd, but I had problem with copying bml3. It stated read only.
Can anyone help me with the command to be able to write my backup efs folder in to the phone efs folder? And help me unlock it too?
Check over in captivate development forum. Good threads there on restoring /efs files.

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

.imei
.nv2.bak

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.
I been playing with my phone for a few days now trying to get it to work and I haven't had much success although I have been learning a hole bunch and now able to load any rom onto my phone easily and flash kernels and such with ease...
The situation is that I received a phone from a friend SGSII I have never had a rooted phone and it came pre rooted, never knew much about it as it is my first Android phone and now love it
never knowing I had to do these things like "backup EFS directory" and such as I know now... anyhow, a few days ago what has happened is I have a stock rom + CF-Root and my phone all a sudden started telling me there is no IMEI and no SIM card present.. after much research, flashing of roms, kernels, bricking the phone, re flashing and so on and so foth....... xda-developers is a FANTASTICK site full of useful information btw now I'm still at the same point but a lot more knowledgeable, I have learned that the problem lies with my efs folder and have found a .nv_data.bak file that is dated dec 31 of last year, at this point it is my only so called backup and hope that it will restore proper functions of the phone, as per some of the guides and other posts and questions I have learned to do this.. so what I have done was copy using ADB my files to my sdcard folder renamed my nv_data.bin to nv_data.bak and my .nv_data.bak to nv_data.bin
also I have used root explorer to copy the hole efs folder to a location on my external sd card and used HC-kTool to make a backup of my efs folder
now I have been trying to use the command to copy my nv_data.bin file in the sdcard folder to my efs folder and it is not working as it gives me msges of write protected file or file exist canot copy... the commands I have been trying to use are
cp /sdcard/nv_data.bin /efs/nv_data.bin
cp /sdcard/nv_data.bin /efs/
I have tried also
rm command to remove the file but nothing has been working...
one thing I should mention is that I have been connecting withough usb cable as I can't seem to connect with that I keep getting device not found so I been using the wireless adb function
abd connect "ip addressort"
I have tried installing the kies driver for usb and the google sdk drivers and none seem to work, in fact kies doesn't reconize my phone aswell... but Odin seems to function through my USB just fine.... not sure if that matters or not but trying to give as much info as possible
Thank you in advance for the help.... this is a great site with very knowledgeable ppl
permissions have to be reset as the back up does not copy the permissions. Use cwm recovery to reset the permissions.
Thank you very much for you quick response, however I have just tried that, booted into cwm recovery, went to advanced and reset permissions, rebooted my hone and still cannot copy the file
Try using a Root Explorer from the market.Connect via wifi obviously if your phone cant detect sim.Phone needs to be rooted.Give Root Explorer root permission and set to R/W from R/O and copy paste the nv.data files and IMEI to the efs folder in the root of your phone,reboot,boot to recovery and "fix permissions" and boot again.
sorry I guess I should of mentioned that aswell but thank you very much for the suggestion... I have tried to edit the file weather just delet it or overwrite or change permissions with Root Explorer and to no success.. also when I push the mount r/w button in the efs folder... nothing happens and the button stays as mount r/w
I found this.Maybe it will help.

Thank, I havent had time to read through them all but I will try tonight and see if I can come up with a solution... I will post here my findings weather they are good or bad..... but thank you very much for the info
I have read and tried and seen all those post, thankyou for the info the problem is still that I cannot modify my nv_data.bin file in any way... I cannot overwrite to it or anything using rootexplorer or adb or any other program... does anyone know of any other programs or command lines to strip the read only permissions on this file as it seems stuck on this and it's driving me insane lol
Gave up
I gave up and had it done professionally, they couldn't figure it out either and had to replace the phone.... Thank you all for the great help, even tho we didn't get it figured out it was great that help was provided
Thank you XDA-Developers your awesome!!

I have an i9100p with nfc. U will loose the nfc but you can flash it back on any rom as far as i know. There is a nfc zip for ics and gb.
read this thread,this should be in the Q.and A
forum.xda-developers.com/showthread.php?t=1455831&highlight=9100p
This is now sorted.
(download Samsung Network/Sim Unlock Code Generator/Patcher (SGS1/2/3) ) - http://forum.xda-developers.com/showthread.php?t=1360174 )
(download superonclick - http://shortfuse.org/?page_id=2 )
extract to your desktop or somewhere you will remember
1. root with superonclick
2. install rootexplorer (or any root access file explorer)
3. copy nv_data.bin from \efs folder to root of memory card.
4. enable usb access so you can see files on memory card on your pc.
5. copy nv_data.bin to a location you will remember
6. run SamsungUnlocker and browse to your original nv_data.bin
7. select samsung galaxy s2
8. click "generate unlock code" IF your lucky you will get the code on-screen, if not you will be prompted to generate a nv_data.bin that has the unlock already applied, save this to a location you will remember (i made a folder called "PATCHED" and put it in there)
9. copy the folder you created called "PATCHED" back to your memory card.
10. dissable usb access.
11. open root explorer and goto your memory card -> "PATCHED" folder. select nv_data.bin anc copy it back to your \efs folder and replace the original.
12. reboot phone. unlock should be done.
if this has not worked, check that there is only 1 nv_data.bin (mine had nv_data (copy).bin. check the date and time to make sure the nv_data.bin is the new one you just copied in, if not, rename the original nv_data.bin to nv_data (orig).bin, then rename the new one nv_data (copy).bin, back to nv_data.bin, reboot and all should be good.
Hope this is of some help, if not give me a should and i`ll be glad to try and help.
ALL THANKS FOR THIS UNLOCK GOTO THE ORIGINAL DEVELOPER OF THE SamsungUnlocker APP

Dude, this is a dev forum not a n00b help desk.
Post topics in General or Q&A after using search, do not post this in dev forum, its for roms/kernels/mods/reference only!
download galaxy s unlock from play store n it will do the needful ..but from next time plz ask questions in Q&A section!!
P.S. I have done it myself on I9100P which m using currently and dnt forget to backup ur efs first..
Bought and activated used phone 2 weeks ago. Phone worked fine thru Friday night. Woke up Saturday to find I could not connect to cell network. Call to carrier revealed my IMEI number does not match the number they have. Somehow my phone IMEI changed to 350000000000006. Internet search revealed many others with same problem. The main difference between their situations and mine is the fact that in almost all of their cases their phone was rooted and they flashed many different ROMS to their phones and something obviously went wrong. My phone is NOT rooted and I have not tried to modify anything. Simple as that. Went to bed working, woke up broken.
I have now researched this the last few days and have no clear answer. Is it possible to set my IMEI back to my correct, legal,clean and not blacklisted value? Any help is greatly appreciated.
My guess is without a backup of the original, you can't do anything about it. Best bet is probably return it to the store you got it from and get a refund/exchange.
Edit:
Fastest and safest bet would be refund/exchange.
Little research has shown other people had a similar issue. Check Nox to make sure the phone hasn't been rooted before, if it has, you know what happened. If it hasn't, chances are the phone was flagged as lost/stolen after being sold (if 2nd hand).
As for a fix, I found this:
http://forum.gsmhosting.com/vbb/f898/g925f-imei-350000000000006-a-2044425/
Recover corrupt IMEI (without prior EFS backup folder)
Items needed
Root Explorer
Efs folder (no need to have a backup of this prior to the disappearance of IMEI folder, but it has to be this folder on the phone)
Obviously having a rooted phone
Instructions
1- With the Root Explorer to back efs folder to the SD Card
2- For safety make a second copy of the folder to the PC
3- Once both copies made to proceed to erase the original EFS folder on your phone
4 Restart the phone
5- When you start the phone, it will automatically create a new folder EFS, Root Explorer to delete the files and nv_data.bin.md5 nv_data.bin found inside the new EFS folder.
6 Copy the folder from the SAI IMEI folder we saved on the SD card and stick it on the new EFS folder created in the root directory of your phone
7- Since the SAI folder we saved on the SD card .nv_data file copy, paste into the new folder EFS generated in the root directory and rename it nv_data.bin phone, then recopy again .nv_data file rename it nv_data.bin.bak
8- With Root Explorer /efs/nv_data.bin change the owner
9. Restart the phone
If all went well you should have recovered the IMEI can check if recovered by entering * # 06 # on the phone dialer.
Thanks for the response ProdigyThirteen.
The Knox is clean 0x0. Everything I have found says the original IMEI is clean and not flagged.
I will definitely look into the procedure you provided. It looks promising. I'll take any sign of hope I can get.
Just tried the recommended procedure but no luck. It is possible that I screwed up steps 7 + 8 because they were not clear to me.

Copy the nv_data file from the SD card to the newly generated EFS folder on the phone and name it nv_data.bin. Then make another copy in the same EFS folder and name it nv_data.bin.bak.
Then you need to set the permissions for EFS folder/nv_data.bin file. They need to be set to rw-r-r. However for this procedure you need to be rooted.

Could you tell me did it work?
No, unfortunately it did not work. After following all the steps again, the IMEI still comes up incorrect. The search continues ..........

Have you tried flashing the stock firmware again? Either by smart switch or odin?
Will try again tonight when I get home.
Callumbr1, No dice on the stock flash. I installed Smart Switch and tried to do the reinitialization. It gets along in the process and then fails in the " Device does not have DRK" error. Also have DM-verity error. I tried to find solution briefly but didn't get far. Ran out of time tonight. Will try again tomorrow. Still appreciate your help.

I remember I did have the exact DRK error on my s6 edge one and dm verity fail. The way I fixed it was by flashing stock firmware through Odin. Quote me when you try again and I'll do my best to help mate.

If you want to get back your IMEI try Dashboard .
you will find all your devices there, then try to find a way to write your IMEI in your phone (may need root)
