This may help anyone who's IMEI got changed or perhaps even deleted by the MIUI MGC 6 or 6.11 update and perhaps even on further updates.
You need "Root Explorer" (or perhaps something similar) from the market and an backup of your original efs folder!
While the initial installation of MIUI there has been a backup folder created on your sd-card. In this folder there is the backup of your IMEI.
To restore your IMEI just copy "nv_data.bin" and "nv_data.bin.md5" files with root explorer to your original efs folder and replace the old files.
After that you must reboot. The IMEI should be restored now.
This worked for me, perhaps it may help you too!
Nice one

This didn't work. I also tried installing EZbase Froyo and the IMEI was still 004999010640000...
Is there a working solution for this yet???
Mosen5, you say to copy to original eds folder. But where is that? Also do I not copy IMEI folder as well (that is within the backup folder)
Its frustrating this as I reflashed this about 5 times now and still stuck with no service.
Updated: Never mind. I found that efs folder (didn't show up with ezexplorer I had used). Pasted those two files and.... it didn't work for me :-(
I even took set it as flight mode, sim out, etc.
I suspect its resetting those files back to what it was because if you try delete them, its back in again straight away. So, pasting those files, would mean it might get reset back to what it had in the first place.
Found a solution. Going along the lines of what mosen5 suggested, but have to use adb command.

Important notes the author forget to say:
YOU HAVE TO SET THE PERMISSION ACCODINGLY TO THE OTHER FILES ALREADY PRESENT IN THE EFS FOLDER,otherwise it won't work
Thx
hi every body
plz help me
i want to restor my nandroid back but i cant
( md5 mismatch)
i need it
thankyou
Did you rename the backup folder using a file browser like Root Explorer? If so, you need to change it back.
If you are using CWMR, then the backup name probably takes the format 'MM-DD-YYYY.HH.MM.SS'. Simply browse into the folder, find the earliest modified file or folder and edit the backup folder name accordingly.
Hi all..
So Im pretty new at flashing androids, been using ubuntu for years and am quite familiar with the terminal as well as computers in general. I made the silly mistake of not doing a complete backup of my phone with CWM before flashing with CyanogenMod 9 and now my EFS folder is "empty" but still with Zero free space... giving the "usual" errors":
1) Corrupt or incorrect ( FAKE) IMEI number. (International Mobile Equipment Identity)
2) No Network and Signal ( calls, sms and mobile Internet not working)
3) No base Band or Unknown Baseband
4) Sim card lock missing
as described in the [A.I.O. Helpline] My Android Solutions.
CWM seems to have created a copy/paste backup of my EFS folder (not .zip and not .img, just a folder) on sdcard/efs/backup but the EFS folder is read only and root manager cant paste into it. I've read that deleting the EFS folder should recreate it, I tried in terminal with
Code:
rm -r /efs/*
and got the reply:
Code:
rm failed for /efs/lost+found, Directory not empty
How do I go about restoring the EFS folder?
Finally figured out how to copy/paste into the read only EFS folder! I have searched probably about a million threads, all say to "just copy paste" into the efs folder... but never how to do it when its locked because of read only permissions.
I think im one step closer.. but still not quite there yet.
The way to get write permissions is simply to open terminal and get root access and unmount the efs directory using:
Code:
umount /efs
After that, I could open the efs directory in Root explorer and mount it as R/W. Automatically, I get some default files there created by the system which I can delete and then I could copy/paste my backup into the efs directory. Bang, mobile network running, but baseband version is still unknown. Also, my IMEI number is the generic one, not my unique one
The problem now, is that on reboot my EFS directory goes blank again... anyone know how to continue from here?

Solution:- Reason is you had Jumped from GB to JB (should be on ICS before JB), so now you need to
1) Download Root Explorer from Play Store and use it to
2) Search you internal SD card for sdcard/backup/efs
3) Copy nv_data.bin, nv_data.bin.md5 and nv.log paste them into /efs in your Phone memory
4) Reboot to get back your original IMEI
If it gets lost after reboot
Remedies for those who have a efs backup
If you Have a Backup and you want to restore it, this is one method Here or you can use the restore function in the app that you used to back it up
If restoring the efs folder or you have a nv_data.bin backup but if you write nv_data.bin or .nv_data.bak it's being deleted on every boot, than follow this [GUIDE] how to get IMEI to stick across reboots to make it stick.
BUT try this method first
Copy Paste EFS folder with root explorer, after paste , power down phone and reboot into recovery and wipe cache before rebooting....this worked for some

Thank you, I had read each thread linking from those threads but it was good for me to do it again!
Flashing the EFS folder with Heimdall gave me the same results as copy/paste, setting the ownership/permissions made no difference in both cases, always empty on reboot.
FINALLY, these are the steps I took to get my phone "working".
1: Odin re-installed the stock I9000JVJV9_OJVJV9_JXJV6.tar file found on sammobile.com as well as the Pit file found on 4shared
2: This gave me an error on bootup... something about "failed to mount dbdata", this was solved with Odin as well by selecting only PDA and using the dbdata.rfs.tar found on hotfile.com.
After this, my phone booted up with the generic imei, a very welcomed change to the previous no imei thats been bothering me! Also, my baseband is showing, the EFS directory is full of files and google play is working... and fortunately, my carrier doesnt seem to care about the generic imei
I'm still going to get my imei back, but first things first! Its time to do some backing up!
Current plan is:
1: Install ClockworkMod
2: BACKUP
3: replace nv_data.bin with the backed up one.
4: reboot / see if my IMEI number is back.
5: BACKUP
6: install CyanogenMod
I hope this helpes someone down the road.. dont be shy on letting me know if my hours of pain helped you!
And... one more thing, my phone is Samsung Galaxy S GT-I9000
Thanks again for pointing me to the right direction
did you only used the PDA included on the I9000JVJV9_OJVJV9_JXJV6.tar file? and how did you use teh dbdata.rfs.tar? thanks.
efs Folder Contents
Hi Guys,
I am hoping you can help me with a problem.
I have a brand new GalaxyS2 i9100, which is on ICS 4.0.4 IMM76XWLPW - XXLQ6 Baseband version, Kernel 3.0.15-1056084 [email protected]#3(SMP PREEMPT Wed Aug 22 2:55:24 KST 2012). The phone is not rooted, but what I did was make a copy of my efs folder to my PC, obviously incorrectly, using My Phone Explorer.
I thought it was just a matter of uploading the folder to my PC and it could be used in an emergency, I thought it would just copy the folder.
What I have discovered, is that all the contents of the efs folder are now on my PC and the efs folder in my phone is empty!!!!
I am now unable to get the files, back into my phones storage.
When I enter *#06# into my phone, the IMEI number shows up and is correct.
I also have a copy of the original efs folder, on my External SD Card.
I have not changed anything else on the phone, other than removing the efs folder contents to my PC. Is there a way, to get all the contents back into my phones efs folder without having to "Root," using say....Emulator or something?
Would a "Hard Reset" on this unrooted stock phone, restore the efs folder to factory settings??
Thank You.

I would be careful with that, if you have your efs folder on your sd card, I think it would be better to copy/paste them with root explorer back before reboot... though this is just a guess. In any case, since you have the folder on your PC, then at least you have the backup you need if you get into serious trouble.
If it did reset, please tell us about it in case someone else needs this info later
efs file restore
Thank you so much. After days of not having calling and texting functions available from a corrupted efs folder, who would have thought that a simple copy and paste of the backed up efs to the system would help greatly?
Hey, this worked for me, but I still can't connect to some carriers.
NOTE: The Nexus 4 does not have a physical sd card. However, the user directory on the phone is located at /storage/sdcard0/ and will, for the purposes of this guide, be referred to as the sdcard.

Making sdcard backups with MTP is often unreliable. First of all, files are not always immediately updated with the ones on your phone. As a result, there may be folders missing, files that you deleted on your phone still showing up, etc. Also, the Date modified values of files are changed to the time that the files were moved onto your computer, which can cause errors when restoring them to your phone; i.e. photos in gallery not appearing in order. Other times, MTP is simply not available (if you have an older computer or an unsupported OS, for example). The best way to go about a backup is by using adb (Android Debug Bridge).
So, let's get started.
1. First, you're going to need some variant of the Android SDK/Software Development Kit as well as the Nexus 4 drivers installed. I won't show you how to do this, as there are already many guides and tutorials available.
Here's the link to the official Google ADT/Android Developer Tools.
2. Once you've got everything on your computer set up, open up the Settings app and go to About phone. Scroll down and quickly tap the Build number tile seven times. You have now enabled Developer options.
Go back, enter Developer options and enable USB debugging. An authorization pop-up will appear; allow it.
3. Now, open up a command prompt window and change directory to the location of adb on your computer. If you installed the official SDK, this will be under
Code:
folderyouextractedto\sdk\platform-tools
Connect your phone via USB and type
Code:
adb devices
You should see something like this:
Code:
List of devices attached
random numbers and letters device
If you don't, you probably don't have the drivers installed properly OR you failed to authorize your computer for USB debugging.
4. Make a folder on C:\ (or whatever your OS drive is) with NO SPACES in the file name. You can now make the backup.
Type
Code:
adb pull /storage/sdcard0/ C:\folderyoumade
You are now backing up your entire sdcard. This can take a while, depending on how many files you have on your phone.
When the copy is complete, you should see something like
Code:
x files pulled. 0 files skipped.
0 files skipped is very important, as it confirms that all of the files were copied over correctly.
To backup specific folders on it, simply change the command to that directory on your phone.
i.e.
Code:
adb pull /storage/sdcard0/folderyouwant/ C:\folderyoumade
5. To restore a backup, simply type
Code:
adb push C:\folderyoumade /storage/sdcard0/
NOTE: Restored folders DO NOT replace existing folders on your sdcard. They are merged (so pre-existing files in a folder remain, while any new files are copied in).

NOTE: I recommend that you do not use your phone during a backup or restore so as to make sure all files are properly copied.

Remember, this is only an sdcard backup. App and system data are NOT copied over. If you want to make a backup of your app data, the easiest way to do this is with Titanium Backup, Helium, or a similar app and then backup those files using adb pull. If you wish to make a complete backup of your file system (not including sdcard though), make a nandroid from recovery.

Good method if MTP failes or crashes! Thanks!
Thanks!
I get remote object '/storage/sdcard0' not a file or directory when I try pull. Help?:crying:

You forgot the frontslash at the end of 0. Try that
On some devices you can't specify destiny forlder in order to use adb push or pull, you have to use current folder:
Code:
cd C:\folderyoumade
adb pull /storage/sdcard0/folderyouwant/
It's better to backup the sdcard this way than using adb backup because it also backups the Android folder inside the sdcard.
Or much shorter;
adb pull /sdcard C:\SDCARDBackUp

Is there a way for pull to skip files which already exist in your specified destination? Sometimes it errors in the middle of a long transfer because it doesn't like a file name or something.
I was looking for a better way to push my virtual sd card backup, as using the copy and paste method in windows doesn't copy all of the files for some reason. It will copy all the files from the sd card to the PC, but not back again. I was having to search through every folder and copy and paste to get everything copied back. Thank you so much for this tutorial. I knew about adb push command, but I never tried it, because I always thought the copy and paste method would be easier. Boy was I wrong. This way pushes all the files in one try. Soooo much easier.
I have a question, can I also backup this file directory: /storage/emulated/0? Or is this something else, I checked both folder and they seem to be the same.
Hi,
I've done a full backup using adb backup, including the whole content of my sd card (using the -shared option).
However, when restoring my device using adb restore, nothing is restored on my sd card (not the apps and not the files).
Am I doing something wrong?
Is there any special option to use for the restore?
Is there any other way to restore my apps&data from my backup file (.ab) using other commands ?
The content of my backup file seems correct though.
Thanks!

Sounds like the adb backup didnt copy the /storage/sdcard0/android/ folder on the sdcard perhaps? Maybe try using adb pull to copy the scdard seperately in addition to doing the adb backup to be safe. You could push the sdcard data back manually if the restore doesnt. See below:

I font understand why is the front slash required?
I also forgot the front slash and was facing the same problem. Now its working after adding the front slash.
So, why is the front slash required and what does it mean ?
can I backup the sd card even if it is external using this method (apps are moved there too)?
edit: ok, I got the android folder from sd card, the message was:
/storage/sdcard1/Android/: 147 files pulled. 0 files skipped.,
but how am I supposed to see them?
I contacted AppMgr III, maybe they can tell me
Lost my notes after Lollipop upgrade. Evernote sync didn't help. But previously downloaded them on my computer from folders HTCNotes and CacheManager. Files inside are just empty folders and have name like ".1425799513711" or files have unknown format and name like "-431985597". How can I get notes from it? Is there a chance? Help, please
