Hello,
because i never actually understood this Nandroid backup, can someone please help me a bit?
So if i do a backup through Titanium Backup, this is a Nandroid backu?
Or Nandroid, is something more specific using another program?
Thanks
nope. Nandroid backup is done using OpenRecovery. It can be accessed using the nandroid menu in OpenRecovery.There are 2 kinds of nandroid backup's now. The old nandroid uses only 1 md5 file for all the images while the new version uses different md5 files for each of the image.
Have a look at this post for a detailed explanation.
http://forum.xda-developers.com/showthread.php?t=698059
so when we use the zipped "update" file when we use open recovery, that's the Nandroid backup?
And thus an "update" file can be created using Titanium Backup?
No. Nandroid contains image files ( .img ). Go thru the link that i posted. It's all there.
Nandroid is a backup of various partitions in your mobile , like the system,data,cache,boot etc.. in .img format.
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

if you have a .tar version of your EFS. Unzip it. Copy all the contents of it, And paste them to the /EFS on the phone. Making sure they overwrite the current contents.
Once that has done, Restart the phone without backing out of root explorer (or what ever app you are using to copy/paste these files).
If that fails, Repeat the above step but ONLY copy / paste the NV_data.bin & NV_data.bin.md5
And finally if that fails. Backup all your stuff using Titanium Backup (or similar) And re flash a stock Froyo ROM. Maybe older, its upto you.
That will Definitely restore the IMEI, Then re-root and go back to whatever ROM you wish.
Good luck.

well i cant paste with ex explorer or root explorer says its fulland when i delete the files in efs the system immdietly make new nv_data,bin so again its full
//
i flashed stock froyo JPU and didnt work :|
i read some topics and i think phone bml3 (stl3) messed up
have you tried nitrality.... download it and make a back up of efs, and then replace the nitrality back up with your back up (sdcard/insanity/backup/efs). Then restore with nitrality.
it restores but not workin weird
Using the thread below, I am able to get an efs_backup, but there is no original efs folder on my phone. it has all the nv_data.bin and files like that, but no "efs" folder on my phone. What is the proper file structure? Thanks

You have no /EFS partition? and still get a backup with the files in it? Use a root enable file explorer and check the very root of the phone for /efs not /system/efs but /efs...
I am running the stock Xperia Play ROM and I don't have an /efs partition either. I haven't tried making backups yet, but I do have an IMEI and I can make and receive calls.
I understand this is the forum for a Samsung phone and perhaps only Samsung phones store their IMEI like this. Is it even possible to lose your IMEI on an Xperia Play?
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.
