I accidentally flashed the wrong stock firmware, wiping my EFS/PDS/persist partition, which means that my IMEI and WiFi are wiped. Can someone please give me a backup of theirs to modify and restore?
Yes, I have tried flashing the correct stock firmware.
My device is the XT1926-7 (RETLA), although any other pds partition from other dual sim model might work.
Also, just having the file structure and the files of the /persist folder would help.
/pds = /persist (symlink)
You can't restore your IMEI with a backup of another persist partition. You need your own persist. Read this:

Although it's for Moto g5 these threads can give you detailed information about your issue. The file structure is the same for both.

My Nook Simple Touch (1.1.2) is now not working because I wiped ALL the partitions before attempting to restore a backup (which I didnt know was bad at the time)
Notes
1. I have two backups:
a) the first is 239mb which contains my ebooks and pdfs
b) the second is the boot partition (77mb) - I backed up again when when noogie was on micro SD
2. So basically (both backups) I backed up the NST without selecting the whole physical drive.
3. After a failed root, I tried to restore the backup (and seeing it fail), I decided to wipe the whole partition before attempting to restore again :crying:
4. Are there any restorable backup images that can be downloaded online? Or anything which can restore the partition table including the ROM partition with the serial address etc.
5. Please help me restore the Nook back to factory or any working state. Cos AFAIK i've bricked the device.
p.s. I have tried touchnooter and installed touchformatv2 but all I get now is a Read Forever load screen. N2Tsecurity doesnt work without the ROM partition.
Please Please Help Me Im so sad (I know this is down to carelessness on my part but I really need help)
Did you really wipe all the partitions (like write zeroes over the entire physical drive)?
Or did you just try to repartition it?
The question is whether you truly wiped out the /rom and /factory partitions.
Sometimes partitioning them correctly you can rediscover the file system.
The /rom partition is necessary, even ClockworkMod needs to be able to see it.
The /rom info is replicated in /factory/rombackup.zip
Renate's solution may work.
Also, there is a tool called testdisk available for linux that I've used to recover data and partition layouts before; I would expect that it may work a champ for situations like yours.
To use it, you would need a linux box or find a windows port and boot the NSTG or NST from the noogie disk.
Testdisk can recover deleted partitions automatically, including the all-important /rom partition.
That one's important because it contains device-specific info for your NST. It'll do it automatically, but you do need to read up on what commands to give it. You can also rebuild the table manually using fdisk (and I've done so successfully before.)
A windows file recovery utility might let you recover /rom as well (or the files from it.)
You most need the contents of /devconf, and there are lots of files there. I am not sure which ones are absolutely required.
I have make the Wrong way.
Created a EFS Backup but the Tool Saved it on the sdcard0 not on the extSDcard.
deleted all inkl inkl the EFS Folder and Formated all Folder (not the extsfcard).
Then i reflashed a Rom and kernel after Android was booted i got Factory Message and the IMEI and S/N was dead.
After search all Folders for the Backup i realized it was on the Partition what i have formated
S/N was easy to Recreate but probaly i didnt found the IMEI files to Edit.
Now i have this Fake Imei 04999xxxx and my Phone unusable now.
Did any way exist to recreate the the correct IMEI.
I have an Copy of the EFS but with the Fakeimei.
Hope any has a Way or Programm to fix it again.
Please Without Boxes or Moneycost Things.
Sry fro the Bad English but isnt my Naturaly Language.

Thank You Soooo much...
my knowledge: "A partition on your internal memory containing important data including the IMEI. If the data in this partition gets corrupt, you will lose your IMEI" it seems to be unique to each phone unfortunately.

But I have my IMEI and when I put another Sim Card (Not my company ) my cellphones read ir as a normally do......
So...
What Can I do now?
My Phone is S4 i9500. I installed the program called SWAPPER. After changing some preferances i run the program and phone shut down. When i start the phone again it stuck on GALAXY S4 Logo. I enter the Recovery mod i realized that error ''not mount efs''.
I know the problem. I remember that SWAPPER use ''mmcblkop3'' as default and i forget to change before it run and SWAPPER formatted the place ''mmcblkop3'' as swappfile format. It means that the places containing efs information formatted.
I install the stoch firmware and using ADB shell and made system working but IMEI is like 0049........ Everything works normally including wifi but phone does not.
1-First of all i need to mount EFS folder. I read many forums but anyhow i coud not mount efs folder. Does someone knows how to efs is mounted? To mount efs can we use ODIN ? and how?
2- Then after i need information to save my original IMEI and the t info to use phone normally.
I will be pleased if someone help me.
Best Regards,
An install of your stock ROM, coupled with a PIT file, should reformat the internal storage and restore access to the EFS partition. However, your problem is that prior to playing around with your S4 you didn't make a comprehensive backup using Wanam's EFS Backup tool. As a result, your IMEI has likely been electronically wiped from the phone as if it never existed. That means that there's no way to "save" your IMEI. Instead, you'll need to have the IMEI rewritten into the appropriate locations in the device, and that means taking it to a service center.

If we write a new IMEI ?
It can be done, but that's not something that can be discussed here. Site rules.
I think my Persist partition is corrupted. Can anyone make a copy of /dev/block/platform/7824900.sdhci/by-name/persist and upload a copy for me? Or any suggestions on how to recover repair this in order to get a cell signal?
