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.
Could i rename my nandroid back up folder the ending tree folder that holds the .android_secure.img, cache.img, data.img, nandroid.md5 and system.img ... like clockworkmod/backup/2010-11-25.05.05.13 could i just pop all those files into a .zip named whatever and direct him to clockwork recovery and flash zip from sd card?
Titanium backup igives you the option to create a update.zip, then it gives you two radio buttons one says titanium backup will be installed as user application and then System application.
I know that the whole create update.zip thing is for flashing it to the rom from recovery. But what is the diffrence bewteen those two options. What is best and what is the diffrence..

By not renaming to update.zip, u can keep multiple versions of backups on ur phone. I tend to take a backup more or less everytime I try to make any changes, like applying themes I do not know, or am not confident of.
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.
Is there any way to change clockworkmod backup to flashable zip. The backup use a lot of space when I move it to my pc and decide to restore back, the md5 checksum doesnt match,
Haven't heard such a feature of flashable zip for CWM backup files. Besides, it's already compressed, so if it's quite large then maybe you do have a lot of files and data in your device.
Regarding checksum not matched; please do not rename or delete any folder / files from CWM backup folder contents when you do backup to PC.

I faced the same problem few days ago, and this solution worked for me.

Story behind this zip file:
I messed up my tablet and I could only get into download mode , meaning I could flash a insecure boot.img and custom recovery.
I noticed that my EFS partition was erased when I entered a stock recovery, I got all kind of EFS error messages in recovery.
At first I tried to restore my system with a original ROM ODIN package but that doesn't restore your EFS. So no luck and still stuck in a bootloop.
So what to do? No adb , no EFS backup on my internalSD , I couldn't get acces to my internal SD.
I google around and I didn't find anything to restore EFS from within recovery or Odin. I didn't have a EFS.img backup on my internalSD so the emwo recovery was no help.
I do have a EFS backup that I took with EFS pro.
That generates a .tar and a .img file.
So I made myself a update package that I could flash from cwm. As I made the recovery I knew in what partition EFS is stored so that was easy.
This is the updater script , it should work on GT-N51... (10, 00, 20) as they all store the EFS in this partition.
Code:
show_progress(0.3,72);
ui_print(" ");
ui_print("1. START INSTALLATION");
package_extract_file("EFS.img", "/dev/block/mmcblk0p3");
set_progress(0.99);
ui_print("------------------------------------------");
set_progress(1.0);
I renamed the EFS image backup that I took with efsPro to EFS.img and dropped it in the zip I made with the updeter script.
Flashed it with cwm and voila, running again without any problems.
SO in the attachments is the zip .
Open it with 7zip or winrar , drag and drop your EFS.img (needs to be this name) into the zip where the EFS-dummy text file is. put it on your externalSD , boot to recovery and flash it.
So I hope this helps the people out that come into the same situation as I did.
Thanks for the zip, I have my EFS backup, but I didn't know what to do if I had this problem!
You are a life saver!!!
THANK YOU VERY MUCH​
Long story short, I was like you. my battery died, and for no apparent reason, I couldnt boot. I had download and recovery but no matter what rom i used no boot. Then i noticed in the logcat it was getting stuck on network initialization and also that twrp couldnt mount the efs partition.
I was looking for a way to restore the efs using adb sideload when i found this, popped in my efs backup and volia!
o yea i'm on the GT-i9300 (s3) but it worked like a charm! deffo keeping a copy of that zip just in case.
I have a .tar.gz efs backup compressed file. So how do I use it to flash via CWM?

OMG...thankkkkks so much....
Anyone have any idea how to proceed if you don't have a backup image of "EFS.img"? Luckily, I am able to boot and run fine, but I understand fixing the EFS will also fix my GPS. Thanks in advance.
