I updated to XXBK3 as per the steps mentioned and everything went fine. When the phone booted, the simcard is not getting detected. I have factory reset the phone, changed the sim, tried my sim on another phone (works on another) but not this one.
Revert back to DDKB2 but still sim card is not getting detected. Kindly assist
Update: I have lost all folders in efs folder after flashing XXBK3. Unfortunately i dont have backup of efs folder
The only option left with me now if service center. Since there is no post for efs backup and restoer, i would request if someone can post settings/commands to backup and restore efs.
Hey, maybe you'll laugh, but there do not give any simcard wrong side. Once I flash phone at night and I'm still there giving the wrong side

I didnt understand you.
What i mean is i dont get network and when i try to open Mobile APN, i get message " Please insert SIM..."
This can happen if you have selected the option Phone EFS Clear in ODIN while flashing FW. This would delete the efs folder.
Follow my guide that I sent you for future. I have already backed up mine, but hope I wont need it.
What is the /efs folder? Should I also back it up? Only that folder or all folders under root are to be backed up?

Efs folder contains information about your Phones IMEI no. If you clear it or corrupt it you lose your IMEI and it can only be restored by Service centre if you have not backed it up. Just copying the folder is not enough. You need to back it up in the form that it can be directly flashed to your phone to restore the IMEI and to put your phone back in usable condition, as in india service providers do not support phones without IMEI nos.
Dude can u give us a walkthru of how to back up efs

Is the link given by manu1991 okay in your opinion? According to Post#2, "An alternative to the backup part is to use Root Explorer and zip the whole /efs folder onto your external sd card. (or wherever you want)". Is this possible and reliable? I tried the option to zip folder in "Super Manager" but got an empty file.
No root explorer should not be used to back up this folder. Follow the link and back up your efs folder.

Ok, I tried this and made the tar.gz file directly in my external sd card. I got a file of size 35Kb? Checked with 7-zip, seems to contain all files. Also made the .gz file using terminal emulator and got same size. In Super Manager the /efs folder seems to be 5Mb in size. I also extracted the .gz file and the uncompressed size is indeed about 5Mb. Can it really be compressed to 35Kb or is there some mistake?

yes, it can. If the files has a lot of zeroes inside. BTW here is only 3 files are very big:
nv_data.bin, .nv_data.bak and .nv_core.bak and as I can see they are have a lot of zeroes.

Yes it is compressed. Just pull out the efs folder out of the archive and see check the size, its 5.03MB for me.

EFS / IMEI changes to Fake frequently.
With regards to your post on EFS restore, thanks for the excellent instructions I managed to get IMEI back but noticed that it gets changed quiet frequently when I am on any version of Gingerbread so I downgraded my self to Froyo and I notice that the IMEI doesnt change, Could you kindly advise me so to get it working when I am on gingerbread. Does it have anything to do with bootloaders. The restore method I used is to flash via Odin and no other commands there on.
ThanK You In advance.
i have the same troubles
i try many methods
last i failed
now i just play t959 as a pda
I believe the Nitrality app has an EFS backup feature
Good morning from Argentina!
I have a problem to restore my /EFS I have Froyo LUBKB1 (Argentina) coming from KPQ and the /efs is broken.
I have a backup from a functional EFS directory but when I try to copy it with Root Explorer, it seems that it copies it but when I reboot, EFS directory is empty.
Is there any possibility to create the .img with ADB from a directory which is in the sdcard?

I have tried to backup my efs folder with various tools, resulting in permission denied. So I decided to manually copy and backup my /efs folder with ES File Explorer (with root permission). Is that enough, or do I need to use some fancy tool?

"rfs"?? As long as you have a backup of your original efs folder on your sd-card & maybe another on your pc, then you're good to go! No fancy tools required!!

It is yes! But in theory, whenever you have a problem with efs, then your bak files in that folder record those changes so you can recover using that particular file! But yes, it's always wise to have a backup of that folder either on your phone (sd-card!) or your pc, because if that gets screwed then you could be in a whole lot of bother!

Are you sure that's enough, since simply copying does not preserve the file permissions ?

Hello everyone I been slowly learning being this is my first Android device. I'm currently on VB and wanted to try out cm7 and like roms. I'm just concerned with the efs problem people are having (which I'm sure it's user error not following directions) .. Also the other thing I'm confused about what is the process to update a cm7? Do I need to backup and restore efs again or is backup stored on the sd card. I will also have a copy of my efs on my computer. I been learning a lot here. And hope I don't get bashed for asking but I'm the type of person who likes to learn so someday I can contribute to others. Thanks again everybody.

Make sure you back up your ENTIRE efs folder to your SDcard as well as a PC. If you do that you can mess up as much as you want and still get your IMEI back. If you follow directions in the CM7 thread you should be safe to convert. If you know how to use heimdall command line and have it installed I do it the old way which I think is much faster. Once your on MTD you can flash between ROMs without having to run any of the backup scripts again. Going back to BLM is as simple as a oneclick with bootloaders(although even that may be overkill).
I was planning to use cwm to convert to mtd and back up efs. But was also going mount /system after efs backup so I can then transfer and backup my /system including my efs files. Then I will continue with the process. Would this be good enough to convert?
Sent from my SGH-T959V using xda premium
Back up your EFS folder first before you convert to MTD. Use a root explorer back up level folder twice. You'll see a folder called "efs". Copy it to your SDcard. Once that is done connect your phone to a PC and copy the folder from your SDcard to the PC. Now you have two backups of your ORIGINAL efs folder. Once that is done follow any of the ways to get onto MTD.

Thank you hechoen for clarifying that. So to upgrade to a new build do I just do the process as a bml rom? Just flash build and restore efs.. In that case?
Sent from my SGH-T959V using xda premium
Yep. Once on MTD just reboot recovery wipe cache data system. Flash new build/ROM. I don't reflash the efs restore but that shouldn't be a problem if you want to.
Thanks so much man for your patience in making me understand how it works. So from what I understand once I'm converted to mtd my efs should restore from one rom to another. Btw I found the efs folder and backed up to sd card and onto the computer will convert to mtd once cm7 11 gets released.. :thumbup:
Sent from my SGH-T959V using xda premium
No worries. Glad to help. Now that you have your original efs folder backed up flash away.
I say you wait until release 11. A lot of fixes and a much simpler flashing procedure.

Has anyone used Recuva to successfully recover deleted files from their sdcard? I tried using it to recover a backup that I deleted yesterday and it hasn't found anything from that folder, even with a deep scan.

I have used it successfully. Recovered about 200MB of deleted photos, but it won't work if a new file has been overwritten in that block.
Files aren't really "deleted" until something gets written on top of them, like another picture in the same place on the sd card
As with other file recovery programs Recuva works by looking for unreferenced data, but if the operating system has written new data over a deleted file then recovery will often not be possible.

Whatever got stored in that block deleted it, whether it be another recovery, or a text file
my phone got wiped last month after an unlock, factory reset or something and nothing recovered the data. i tried partition recovery, getdataback, easyrecovery, none of them found data. might have better luck getting stuff back that was just deleted.
I was on CM11 and One day i lost the IMEI number of my phone and lost all network. I think i flashed an update, dont remember clearly. I think the EFS folder was corrupted. I gave the phone to samsung service center and they were not able to fix it. Can any one help me? I dont have any backup.
ANyone? I tried flashing the stock value pack, didnt work
Cm11 suppose to do a efs backup in SD card. Look for it, if found replace efs folder with it and reboot. May work. Good luck.

Oh man!!! I flashed stock over it and there was no sd card, only internal sd! Any other method? Flashing regional stock or something?
I seem to be having the same problem as this except(android.stackexchange.com/questions/61531/removed-storage-emulated-0-file-and-lost-access-to-all-files) there was never a solution. I tried remaking the folders and restarting the phone but that didn't work.

Soooo you wiped internal storage? Pictures are gone... Best bet is to try Disk Digger or some similar app and see if it works. Also make a backup next time before you do whatever you tried to do as to avoid this situation in the future.

I was going to, except to make a nandroid backup or backup in general using custom recovery I need to go have more than half of my sdcard be free space (since it back it up to the internal sdcard) and I only had like 500-600 MB free I know you can move nandroid backups to the computer to free up space, but I do not know if I could backup straight to computer since N5 has no space.

From my understanding, a nandroid backs up everything on the selected partition. So /system would save your ROM and its settings, etc. Normally on a phone with a SD card it won't back that up, but the N5 only has internal memory. Backing up /data won't save pictures and videos you took?

It's not possible..
You're scanning the drive for actual files on the drive that no longer exist in the filesystem. Think of the file system as a database that tells the OS where the files are. When you delete a file, it doesn't really get deleted. Just the database entry about it.
The files exist whether there is a database entry in the file system or not but if you think about it, unlike files , the folders don't really exist on the disk.. When you create a folder, it doesn't really create a folder on the disk. It just reflects the "location" in the database. Folders don't exist on the disk so they cannot be restored. Restoring the files just adds new entries to the file system. It cannot find the deleted entries and reconnect them with the actual files
Hope this clarifies what you're seeing
