Whenever I Try To Restore, It Does Not Happen And It Shows MD5 Mismatch! In CWM! :|
Help!
P.S.
I Followed Every Step Correctly!
what kind of CWM are you using, is it temporary?
or do you have a custom kernel on your phone?
I'm Using Stock Kernel!

Change the name of the backup and make sure there is no space between.

let's go to the basics
first make sure to flash your back up based on the cwm used to back it up in the first place
second check if your back up is placed in the clockworkmod folder and has no spaces
if the above fails then flash the stock firmware of your back up then restore your back up
ex:
your back up was based on DXKL2, so to match the md5 flash DXKL2 and restore your back up
ps: worked for me
Try using Cwm by madteam..

can u open .md5 file n tell wats in it?
the most posible reason behind these problem is because the backup was not succes or there was problem with the sdcard. try to reformat your sdcard in your computer without using quick format option. after that try to make a backup and restore.
good way

Hi,
I came from Galaxy S2, on which I learned that it is crutial to backup the /efs folder with nv_data.bin file immediately before messing around with the phone.
unfortunately I can't find the nv_data.bin file on the S4 in the /efs folder or subfolders. Where can I find it?
I have an unlocked rooted i9505

Hi,
I am using root explorer and see the contents of /efs, but there is no nv_data.bin file in there. Is this file located somewhere else on s4?

Hello,
I am a bit anxious about my phone. It works well under omega 3.1 but I was checking my saves and I foud that:
1) My EFS folder is empty
2) I have two efs backup files but they seem rather small (35k each) ans they are dated 1970 I am pretty sure they are empty
3) my IMEI is correct when I go into about phone (But does not appear when I dial *#06#
Is there something wrong ?
The Imei seems good but as the efs folder is empty it should not...
Any idea ?

I am not sure how to do it with terminal emulator.
After flashing TWRP recovery and while the phone was brand new I made a full backup of the phone and inside there is a efs backup wich is 35k
Also I made another backup made with twrp recovery and it is 35 k again for the efs.ext4.win
Is that a normal size ?

I did it and it created a 13.62 mb file.
However I dont know if there is something inside as there is no file in efs folder. It may have copied blank data ?

Yes I did it also for the m9kefs partitions and everything is stored in safe place.
Many thanks to you !
My efs (files and folders inside) is 3.xx kb and is correct.
The whole partition of efs is about 13.xx mb.
Even the efs folder has no files in it or have,
the size of the partition remain the same.
Thanks.

And any idea why the efs folder is empty ? Is the efs a hidden partition and the folder just a dumb file or symbolic link ?

what explorer are you using?
download attached file manager, install it. open it, go to the settings of file manager, check "root explorer" (grant permission) and check "mount system folder". now see efs folder.

There's an app called KTool that I think can restore EFS .tar files.
Or install EFS Pro on your computer and do it that way
