Hello everyone. I need help locating the NV_DATA.BIN file in my Bell locked Samsung Galaxy S2 (GT-I1900M). I just purchased this phone and would like to unlock it with Grooby's unlock tool but after spending an hour searching everywhere I cant seem to locate this file. I did find the efs folder but its empty inside. My S2 does not have an external SD card. I have two programs running which I used to search for the file, ES File Explorer and File Expert.
Any help would be appreciated as I am traveling soon and need it unlocked. So frustrating being a noob when Ive used an iphone from day one and now just want to try something else.
If your phone isn't rooted, you're not finding the files. That's by design. Imagine if everyday users were able to delete those files. Lots of borked phones with no/generic IMEI's.
If your phone is rooted, it's in /efs.
Edit to add - Which I guess will lead to the next question. How to root your phone in this thread.

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...
same
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
samsung advance sin imei ni nv_data.bin
hello my samsung advance imei not displayed and entered the efs folder and I find no data data.bin bak as I can do to put a generic one at least? or if someone is kind enough to pass me those files so I test if it works ... thanks!: Crying:

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..
Hi. i cant understand the sticky threads at all. i have read it 1000 times.
Lost the signal after flashed Imperium ROM.
I believe i can recover that by restore a cwm backup i did some time ago ?
BUT i have formated the internal phone and no restore files are located. I have it on PC but
have not been able to copy the backup folder to the phone so that CWM can find it ??
And the stickys makes no sense to me..
Damn it.
Just knew i was going the wrong way in Imperium AROMA installer .. :/
Any help plz ?
I have found a way in the forums to find the files in CWM...
/data/media/clockworkmod/backup..... I put them there and i could find the recovery file.
But i just glanced somewhere that i wont restore them modem . :/
Anyway its restoreing, and i hope it works.
If you made a full nandroid then it will restore your modem, but not your efs folder - which is responsible for most no network issues.
You'll have to read through the stickies, particularly the 'before you root' and 'imei know this stuff' ones. I'm not going to type it all out for you.
Follow the instructions to flash a stock ROM with an EMG4 baseband, which solves many efs issues. If it doesn't then you'll need to pay for a repair, about £20.
just realised its bricked.
i have a copy of efs folder on pc but not sure what to do.
EFS Proffesional cant find a backkup in restore tab, even though i believe i did make one.
In my efs folder are.
bluetooth
drm
factoryapp
emei
wifi
and 7 files.
can i copy and paste something to the phone to make it work ?
Yes , copy those backed up efs folder files to your phone's efs folder and reboot. It should work.

I would recommend using ADB as copy doesn't retain the required permissions.

I use root explorer to copy paste and it did retain permissions but yeah to be on safer side using bridge is more preferable

Yes root explorer may be better than other file managers with root permissions to be fair. But most people think root exploring is a simple thing that can eb done by any free app
hi and thank you.
I was not able to copy efs folder to phone, or to say, i managed to copy it via Es file explore to the root efs.
But phone ended up with Factory error, so now i have the screen thing on the phone.
I tried to type the guide from root SU in Terminal with no luck, nothing worked or would be regonized, sadly.
I read somewhere that i stock rom might solve the things, so thats where im going now.
I have removed binary counter to 0, and it says im on stock firmware and recovery.
I have installed stock recovery.
BUT im stuck at finding my STOCK ROM.
Im using THIS guide......

This is because you did not follow suggestions. ES will not do the trick because it will not retain permissions. ADB was your option, or perhaps root explorer.
I did try this page http://developer.android.com/tools/index.html and downloaded SDK pack.
Its pure madness to me, and i was unable to find something that looked like a file browser.
Root explore i did look at, but it did cost some money. And maybe it wont work !

FX Explorer and Root add on is free .
Service centre repair is relatively cheap .
I have paid 5$ a month in some insurance, so last resort is i smash it with a hammer so they wont be able to connect it to a computer.
And get a new one. But i wanna learn this stuff for the future.
I tryed fx explore, and the Factory mode has gone now. But still no network, and eimei says null/null ?

Hey guys, worst part about samsung devices is always their EFS issues.. my samsung tool app has already gained support for SM-G900A, SM-G900F, SM-G900H, SM-G900T before root and custom roms are available, so first thing is first, root(when available) and backup EFS!
ive kept all downloads and discussion within the original thread here! - SAMSUNG TOOL APP HERE
this was made possible by leoaudio13 dumping his partition table!

thats because nothing was accessible until after root, dumping system was easy, but any other directory/file on the device wasnt able to be read after until being rooted..
samsung didnt even include tar binary so I dumped over adb, then CF helped root and then we dumped raw images!

For full backup, which partitions do you recommend?
Galaxy S5 SM-900P Partition table
you can still simply create a copy right?
I have always had rooted phones and my SGS 5 is no exception, it got rooted using CFroot in the carpark immediately on picking it up.
I have therefore always simply made a copy of the efs folder on to the external sd card which is then synced to my dropbox.
However I have not really kept up to date with developments in these areas, so my question is nowadays is this still enough to ensure the safety of my device and it's ability to connect to my carrier. In the past when I have had issues after flashing roms and things simply deleting the /efs folder and copying the contents of my back up into it and rebooting has always been sufficient to get my carrier back up and running is this still the case with the international SGS5 qualcomm variant or do I need to consider other elements?
When will it work for SM-G900V? I just rooted my phone today and would like to use this for my backups. I just tried it by using EFS backup and now it's stuck on a triangle with an exclamation mark that says Please Wait. Ugh! Help...
