first tell us the details of ur recovery Image (Name with extensions and size ) and then try burn it and let us know the info about ur partition details (pic of partition wizard or use fdisk)
anyway before do anything take back up from ur current nook before do anything
best regrads
Hi all, I'm a new I9195GT owner (for a week already) and have been researching and having some satisfaction rooting and restoring all my apps with Titanium from my previous smartphone.
The phone works fine and I'm quite happy with it. I've already done a full backup with CWM recovery for any trouble I might come across in future but I don't know if a full backup from recovery contains all important and sensible data like EFS and NV data. Those two things are totally new for me as I'm coming from a HTC Desire which didn't require attention to those sensible points.
So I would be very grateful if anybody clears some doubts I have relating EFS and NV data:
- Does a full backup from recovery contain EFS and NV data, so in case that flashing a custom ROM results in corrupted EFS data, I would fix it just by restoring the full backup from recovery?
- What is the best and safest way for backup EFS and NV?
I've seen this post from arco68 which states a command I guess should be executed from Terminal directly in the smartphone, but I don't know how should that .img file restored to the phone in case it becomes corrupted.
I've also seen this post about the EFS Professional tool from lyriquidperfection but in the whole post I havent found anybody confirming it works in the S4 Mini i9195.... so it sounds good but I don't want to brick my new device being the first one to run the tool with the i9195
Thank you very much
As far as I know CWM does not back up EFS.
The good idea is to use TWRP recovery instead of CWM. TWRP does backup EFS.
You can get TWRP for 9195 here

Thanks for the idea. I'm ready to install TWRP recovery but, before installing it and replacing CWM,
Is it possible to launch TWRP recovery from CWM recovery, as temporary? And when rebooting CWM is back.
I remember doing something like this in my previous device: from 4EXT recovery launching a CWM recovery for some particular reason I don't remember

TWRP Recovery does not backup full EFS. IMEI is not included at least. Even though it lists a possibility of EFS backup, all it does is backups /efs partition. which does not contain IMEI in it. This concerns specifically I9195, which I own too and am researching this issue and also lost IMEI issue.

I already had installed TWRP and made backups and nandroids....
So how can we safely backup IMEI in a way we can restore it in case it gets corrupted?

Guys!
The most simple method to backup our IMEI (efs folder) is:
1.Install rootexplorer
2.open it with superuser permission
3. Copy efs folder from root main folder to your sd card.
4.Upload from sd card to clouds to be sure you have a backup a different places.
5. Push thx for me

I did already that too, not with rootexplorer but TotalCommander which also has root access to any partition, I guess it performs the same backup just copying everything.
But then I don't know why it is valid to do "raw" directory/file copy with root explorer but it is not valid an EFS partition backup with TWRP recovery. I'm a newbie with this but, it seems the same to me....
Can anyone tell exactly in which file is stored imei? Isn't the same structure/process valid for other Galaxy brand smartphones so we can follow them?

I repeat, EFS FOLDER / PARTITION even on a raw byte level DOESN'T CONTAIN phones IMEI. This concerns specifically Samsung Galaxy S4 Mini LTE (I9195).

Normally, phones IMEI in previous galaxy devices (don't know about current S4, I own S4 Mini LTE), was stored in nv_data.bin file which was located in /efs folder on root. (which is a mount point for mmcblk0p10 partition in S4 Mini LTE). But, in this device, there is no nv_data bin file and IMEI is not stored nowhere close to efs partition. Not too many people own S4 Mini's and almost everybody whom I asked an information based their knowdledge on another devices and were feeding me false information I heard over and over again.
To clarify something, I know, that EFS partition doesn't contain IMEI, because:
No file in efs mount point contains IMEI.
No IMEI found checking EFS Professional backup (tar) on HEX level using various search methods. Even through-looked it, file is not that big.
No IMEI found through-looking .raw backup made using cygwin (which contains every single byte of partition, even though it is not a part of a file), which is 95+% warrant, that IMEI is not in EFS partition.

Thanks mate. Pretty clear :good:
I was also not confident about some tutorials I read in other forums claiming that just doing a copy of file structure from /EFS folder would backup our IMEI. Your explanation is appreciated.
Hope to find some way to effectively backup sensitive data as IMEI is....

Found it! Making guide right now. Basically IMEI is contained in both mmcblk0p11 and mmcblk0p12 partitions. Samsung apparently has developed a new error-safe phone nv data preservation system, I'll explain in details in tutorial.

How do you mount those partitions? I've tried with no success. All I get is "mount: No such device".

Don't mount, just backup.
Through terminal emulator, enter commands
su
dd if=/dev/block/mmcblk0p11 of=/dev/block/mmcblk0p12
And how to restore later if IMEI gets corrupted/null?

Could you (or someone) PLEASE post or send PM with backups of partition mmcblk0p11 and mmcblk0p12? While researching this issue, I trashed 2 OF MY PHONES and nulled my IMEIs because of delusion caused by memory of having a backup, which I didn't. It's a pity to give away such a fortune for spares. I need NV blocks to hex compare them with blocks I got from another healthy I9195. Since IMEI numbers of different phone blocks will be different, difference will show on hex level too, which will help me determine exact address of IMEI location, after which I could modify my trashed NV blocks at determined memory address with my original IMEI, which could save me from watching at useless brick. And also would help me at development of I9195 IMEI Restore tool.
Disclaimer: I am not modifying my IMEI nor doing any actions which end-target is modification of original IMEI and differing it from original one. I am modifying nulled (trashed, unoriginal) IMEI to its ORIGINAL state which ultimately couldn't be called nothing else but RESTORING. I won't use IMEI from gathered NV blocks. I just need a another healthy block to fix my issue and help develop tools so others could be able to sleep at nights without issue that causes me sleepless nights.

I haven't done yet any of the backup processes you explain, so I don't even have the files you're asking for, but with all the gratitude and admiration I feel for the developers I wouldn't feel any confortable sending sensible data from part of a nandroid backup.... speaking just for myself of course, if I could choose how to help a developer I would preferr doing a donation to help him recover the hardware he has broken to help others. Some months ago I heard a friend telling that he had been scammed with a phone he bought in some cash converter and only worked for one day, then it became with null IMEI, and he suspected someone had "stolen" or "shutdown" his IMEI for unknown reasons...
sorry to say that, maybe I'm an ignorant but I just don't feel confortable with what you are asking directly to me
so i restored a persist backup from the moto g 1st gen by mistake through twrp
I noticed I had data but not able to make calls
i've tried copying my mums /persist folder ( she has same Moto G5 )
but the sim card doesn't get read at all then
is there any permissions i need to give the certain files??
Or can I use any adb commands to back up the persist partition?
Hey i have bricked bootloader but i think other partitions are alive, can you help me with this:

If i make it go live i will give you my /persist, thanks.

Honestly I have no clue what you have done but uhh messing with partitions isn't a good thing :/
do you know what partition that was that you erased by accident?
Every partition, but its ok now i sent the phone for jtag and well see if they can fix it
Hello guys,
I have a question, yesterday I made a copy of all the partitions of the phone, one by one ... in qfil, using the partition manager.
The thing is, I wanted to test things and save my setup before formatting.
When I finished testing things, I started flashing the partitions one by one again. When I finished, I turned on the phone and I got a screen that said:
"Could not decrypt (or something like that), memory will be erased." Then it started to format data alone. And the Rom appeared at boot with nothing of mine configured, nothing of the backup, just like a factory reset.
Can someone help me to know what has happened? Do I need to flash the dm-verity-forceencrytp when restoring with qfil?
All I want is to restore my backup of .bin files
Before restoring, I flashed the base kdz of my backup. I do not understand that it could have gone wrong, or it could have gone wrong, and the backup is done by another method, other than backing up each of the partitions.
have you found any solution for this ?. I have the same problem.
