[Q] Nandroid backup help

Need help restoring a old version of nandroid backup. I cant restore it with CWM 5.0.2.7
Files that are inside the backup folder:
.android_secure.img
cache.img
cust.img
data.img
nandroid.md5
system.img
When i try to restore it with CWM 5.0.2.7 it just says that boot is missing.
What version of CWM i need to take that i can restore it.

Calling Dr.Ketan need to reach you

Dear Dr.Ketan
since I have recently registered I am unable to post anything on the development thread. I am facing a serious problem. and I am asking you this because I had backed up efs.img 20 Mb and it has helped me restore earlier. but now it's failing to restore my efs. I am explaining the problem below.
I have a sm-n900 exynos and I have lost my imei and baseband during a Samsung flash. I have a TWRP backup, efs.img backup by dr.ketan's backup tool but nothing is able to restore my efs. I have scanned emmc blocks for bricked blocks and all blocks come back as non-corrupted. may be the partition is corrupted .how do I erase my efs partition to rebuild it. I have tired to flash PIT from ODIN but that too doesn't work.
1. could you tell me if it's possible to extract the efs.img to the efs files and will it help.
2. do you think there is a way I could retore from your tool using some other method.
i have tried the following things too
tried this post http://forum.xda-developers.com/show...567133&page=36
but need a guide to identify the partitions and how to rebuild them. by any chance if you know if I could extract twrp backup to files to restore efs or from efs.img so I can use the nv_data.bin, since tried restoring the backups and it didn't restore I feel the partition might be corrupt and hence not being re-written. so might be I have to rebuild the partitions by formatting as explained in this thread. but I don't know exactly the steps for exynos variant. I tried using terminal on twrp but mkef2 command shows mmbcblkp03 doesn't exist which as I have read in posts is the efs partition on this phone and reboots to twrp recovery. and mmbcblkp12 show filesystem too small and reboots to twrp recovery

[Q] custom recovery location in the file system

I found a collection of bin files for the stock 24a partitions and after overwriting the "recovery" partition twrp is still installed.
Which partition do I have to overwrite with stock to clear out TWRP?
Or a simpler question, Where in the file-system is TWRP located?

using efs professional I cleared my efs folder. now my phone is stuck on tmobile logo. i do have a efs.img backup. i have tried to flash my efs on odin but i need a tar.gz file.
i have tried to flash twrp, but then it wont boot into recovery. i'd appreciate any help.
