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

[Q] need help efs nv_data.bin not found samsung vibrant

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:
no nv_data.bin found
Hi there!
My 2.3.3 is rooted,
there is no /efs folder and
nv_data.bin was not found in the system.
what can i do in this case!?

[Q] No Imei?, No Baseband?

I have no Imei, No baseband, No reception (obviously)
ive been running cognition 1.51
and have downloaded csc selecter or something similer (that never worked) but i think that may be the issue when i opened it..
But i was wondering if there is a fix for this yet? or if someone can help me with resoring my phone to factory including the format of the efs folder?
ive searched for help about this, but noone has seemed to come up with a solution..
any help would be greatly appreciated

Just reflash modem.
If you didn't back up your efs folder, you might be out of luck. Try flashing the stock firmware for your provider and see if that helps.

all the flashing i have done over the past year with my sgs i9000 and now sgs2 i9100 i have never seen anything todo with efs.
so no i havnt backed up that folder, that cant be the only way to fix this?
i have looked in my efs folder and there is some files with .bak in them so im thinking some of the roms ive flashed in the past may have done a backup or something?

If you are missing baseband, there can't be imei either so flashing modem should restore it.
Happened to me a couple of times.

It means you still dont have modem for some reason.
If you have flashed new kernels recently, go back to kernel which worked and then reflash modem.

When you changed CSC, Your IMEI got corrupted. Only way to restore is efs back up or reverting back to original firmware. This should work ...
If not , You may try this one , http://forum.xda-developers.com/showthread.php?t=837239
I was able to solve it using this method. You need to be rooted to do this ...
This will void your warranty ... so be careful.
I would definitely not recommend using a i9000 method of getting the baseband, imei back on a i9100.
The EFS folder contains critical files for the IMEI, Baseband, serial number of the phone etc.
Check in the Q&A threads and in here someone else also had the same issue and they managed to resurrect their phone with some developer support.
Good luck, only other option is a repair job and just say kies crashed through the firmware update and now the phone doesn't boot.
Please use the Q&A Forum for questions Thanks

Thankyou for putting me in the right direction Virtualsk
if you arent using a pit file dont touch the re-partion box or your will screw your phone completely and dont tick the EFS box either although now that doesnt matter as its already to late.

Trying to copy nv_data.bin and FAILING

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!!
ive the same issue,got a rooted s2 with cwm all the forums cay copy the efe data but i cant find a way,anyone know how to do it?,i need to eddit it to unlock my phone:ie the simlock.
thanks
thank you for sharing your ideas

Where do I find the NV_DATA.BIN file in my S2?

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.

NO SIGNAL / IMEI NULL / BASEBAND FIX EFS Samsung Galaxy s3 shv-e210k

Hello guys, i have the solution to this annoying problem.
The problem itself is that the file nv_data.bin suffered some change or was deleted by installing a ROM or when you flash your phone.
The solution is change that file with one that is in good condition, but can not be from any phone, it must be of the same model.
I will leave the required folder to resolve this, this folder is called efs and I got it after 3 days of searching.
Thanks to the user BarakOsama who was that uploaded it.
Well, this are the steps you must follow:
1- You must be root
2- You must have the application Root Explorer (get in the playstore or google)
3- Download the file EFS-SHVE210K.zip
4- Unzip
5- Copy the folder to your phone
6- Open Root Explorer and activate the option "mount r/o"
7- Copy the folder to the root of the phone and replace the old efs folder (make a copy of your EFS folder in case a problem arises)
8- Reboot
This has to fix the problem definitely.
Well I hope this help you guys!
Sorry for my english, im from Uruguay
Thanks again to the user BarakOsama!
