Forgot to have nandroid backup . Wiped data, cache partition, dalvik cache, battery stats Couple of times. Screwed up the phone for flashing, No signal.. Later, I was able to fix it with SGSII_repair But, stuck with a generic IMEI (004999010640000). I haven't backed up efs folder. Now I'm only left with cryptprop_es in the previous efs folder.. Is there any way to restore original IMEI ???

Try this ! You must have:
-Root
-Root explorer for copying files to and from EFS folder
-Android SDK for the ADB tools or Terminal in your phone.
IMEI is stored in ".nv_data" file in ORIGINAL SHIPPED EFS folder too, so you just have to do these:
1) make a copy of your EFS folder to your sdcard using root explorer and then make a backup of the folder to your computer [ to have another copy if you had to format sd card sometime ]
2) delete the EFS folder (BE SURE YOU HAVE BACKED IT UP IN A SAFE PLACE AS SAID IN STEP 1) from the root of your phone using root explorer.
3) reset the phone, after that, go to the root, and you can see that the EFS folder is still there, don't make any mistake, this EFS folder is new and generated by the android OS.
4) go to EFS folder using root explorer, and delete "nv_data.bin", "nv_data.bin.md5".
5) go to your backed up EFS folder on your sdcard, copy the "imei" folder to the EFS folder at the root of your phone, then again go to the backed up EFS folder at yout sdcard and copy the " .nv_data " file to your EFS folder at the root of your phone using root explorer, NOTE: the dot in first of nv_data is not a mistake, copy the ".nv_data" file.
6) make another copy of the ".nv_data" file in EFS folder in your phone, so you would have 2 copies of ".nv_data" in EFS folder
7) rename one of ".nv_data" files to "nv_data.bin" and another one to "nv_data.bin.bak"
8) at your PC open CMD at the ADB tool path, or run Terminal at your phone enter these commands:
adb shell ( use this command of you use ADB, if you're using terminal, skip this line )
su ( ALLOW THE MESSAGE CAME AT YOUR PHONE's DISPLAY BY SUPERUSER PROGRAM )
chown 1001:radio /efs/nv_data.bin
9) reset your phone.... after that you have your original IMEI. you can check your IMEI by dialing *#06#.
If all the above steps do not work, check with a called developer Odia on XDA, he has recovered many phones with lost EFS.
All the best.Hope this helps!

I don't have the nv_data files or, anything related to that !!!
Have you tried GSII_Repair from the Market ? This might be your last best chance before you need to send it to Samsung/your telco for repair. Look for it, read the description & then decide whether you want to try it or not.
If this doesn't work, nothing else will.
Edit to add - My bad.

Yeah !. This is the App Which Has Set The Generic IMEI & Brought Back The Phone's Signal !!! Would it Be A Problem in Future if, I Stick With This Generic IMEI ??? (I Know That Some Operator Blocks This IMEI But, Mine Didn't, Yet..)

He says in the opening post he has tried GSII_Repair which gave him the generic IMEI.
OP, if your EFS folder is empty and you made no previous backups I suspect you will have to send it for repair.
Imei is known by telephone company?
Can't he just get imei from them and create new folder if there is no backup?
Isn't imei on phone box?
Sent from my HTC Glacier using XDA App
The necessary files are encrypted. Even if he knows the IMEI it's not just a simple case of creating a text file with it in for example. I wouldn't be surprised if his MAC address has gone too.
Do a search for the post about user ODIA who has helped some with no IMEI .

I believe you have to remount your root folder as R/W.
Are you using a rooted phone with root explorer set to read write ????

You can restore the efs file with kTool by Hellcat, it`is in the Playstore. First place your backedup efs file in /sdcard/efs.image and then restore. Haven`t done it myself yet, and you better google it or wait for other advices by people who actualy did it. Good luck

I haven`t restored my efs ever, so i`am not 100 % sure it will work. The esfile explorer file should be an .img file i think. Betterwait for someone who knows more about this stuff. Don`t you have a working backup in cwm that you can restore and have your imei number back?

Using es file explorer or root explorer mount system as rw and delete the current efs folder. Then copy / past the copy you saved and reboot. Original imei will show again.

Did you first delete the current efs folder? Maybe try again and delete the factory folder as well and confirm the remaining efs folder has nothing in it. Then past the copy efs folder and reboot. If that doesn't work then possible you don't have a full copy.
My backup of those 2 folders have have 19 items in each when viewing in My Files. How many does yours have?

What format does you backuped efs file have, tar or zip or something else.
It's easiest to do it in Recovery mode, make sure /efs and sdcard are mounted in Mounts&Storage.
Connect to the phone over ADB, then copy the contents of the backed up folder to /efs and restore permissions
Code:
cp /sdcard/YOUR/EFS/Folder/* /efs/
chown -R radio:radio /efs/
chmod -R 755 /efs
Then reboot the phone, hopefully it will work. If not, please attach the logfile from the /efs folder to the post so we can see what goes wrong.

Log file from efs?
Hello, i have used ktool to restore my imei, but it ereased all my efs folder files, so now it is empty. I have made my imei backup using ktool app, so i have efs.img and efs.tar.gz files.
I have tried to flash stock rom with odin but not only one of them boots, they all get bootloop. My phone only works with cm9 but it has no imei and no network.
So i need these files from efs folder, could any one help with this? Or is it possible to restore them with my back up files?

A simple copy and paste worked for me using root explorer.
If you have efs back ups:
Delete entire efs file on the root of you phone and reboot. Upon reboot a new efs file will automatically be created.
Copy the efs file back up and place into the newly created efs file at the root of your phone. Reboot into recovery and wipe cache.
This method restored a corrupted efs file on my s3.

I have only two back up files: efs.img and efs.tar.gz, but efs folder should contain much more files.
I delete efs folder in the root and restart phone, but anfter restart it only creates the efs folder which is empty.

Ktool must of made a back up an empty folder. Don't know what to tell you. Do you have any files in storage called efs_backup? I think some recoveries or kernels automatically back up the efs file when doing a nandroid. Find the earliest back up and copy and paste.

I read on some other efs problem threads that flashing some newer firmware (ending with mg4 or something like that) reformats the efs file and you have to flash different firmware in order to fix from back ups. Look into other threads, they might have the proper procedures to fixing efs.

Trying to flash firmwares and roms with these endings, but the phone doesnt boot, just stucks on samsung logo and repeats animation. It might be because i was installed leaked 4.2.2 xxufme7 firmware so it cant downgrade to 4.1.2 firmware.

Just a thought are you doing a factory reset between flashes also doing a factory reset with stock recovery will wipe your entire internal sd
Have a look at EFS Pro to restore a tar .

This might be my misstake.
By the way, this is solved already. I flashes stock 4.0.4 version and used ktool to restore .img and .tar files, after reboot network came back and all efs folder files were also back, then flashed atock MG6 So now i am on this stock firmware.
But i still cant install leaked version FMU7, it gives me fake IMEI and no network, any ideas?

no need to back up efs folder just for rooting your phone! you can not find any files in efs folder until your phone is rooted and es file manage is enabled root permission.

yes, when ever you root your device, back up efs via philz recovery or any apps you would like to.

My IMEI is empty and phone does not read sim card.
I have read this tutorial: http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021
I have root access and I can see the files in EFS folder with root explorer, but can't delete any of the files. I also can't mount EFS folder to r/o.
Does anyone know the solution?
Update: I have flashed a custom rom and everything is fixed.
If you don´t have backup its a fail. You must find someone who own service box. F.E autorized serivce and pay
