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 ?

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.

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

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.

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.

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

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.

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.

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.
