EFS Folder deleted - SGS fu** up - NO BACKUP

Hello,
i googled and searched for hours but can't find a solution for my problem. It looks like i lost my whole EFS Folder when i wanted to flash Galnet MIUI and after that CM7.1 because it failed.
So:
- CAN'T Flash ANY CWM zip (Status 7 error)
- CAN'T use mobile connection (No SMS,no Calls,no Internet etc.)
- NO Backup of the EFS folder ...
- Able to flash any ODIN/Heimdall ROM
- Up and Downgraded 100 times from FROYO to Gingerbread and so but still no EFS rapair :/
HELP,please ...
UPDATE: If anyone is wondering what i have done - i sent it to Samsung and they repaired it for free and even 4 months later it works like a charm (with ICS )

Flash any ROM using repartition. If that doesn't help, flash any modem / kernel after flashing ROM.

Already done that,no change...

miui creates a backup by itself in sdcard named backup

Check your internal SD card, it should be there.

if you don`t have a backup of your efs folder... your imei is lost forever.... you`ll have a service imei 0040etc .Efs folder will be automatically rebuilt but this will not get your imei back... i sent my phone to a Vodafone service for another problem and didn't canceled my warranty so its no problem

Nothing what you posted works. salesale's link was good,but i dont have a backup on my sdcard so its useless ...
I was NOT able to flash MIUI/CyanogenMod so i even dont have this backup ... and all my sdcard backups are only folders like DCIM/Music/Videos but not the whole sdcard. Before i tried to flash MIUI i backuped my whole sdcard but theres no efs folder there with a backup :/
I think i cant send my phone to samsung. they will cancel my warranty because i cant call and say my IMEI / efs folder was deleted without any reason. they know i have flashed and have fu**** up my phone.
Any other suggestions? :/ can someone send me his efs folder? Maybe the phone restores the imei when i follow the tutorial from salesale's link

Flash the latest official firmware for your country and Just go to the service center and tell them that your phone doesn't work after update with KIES.
That's all! You don't know why this happened
Since there is no need to open the phone, your IMEI needs only to be rewritten. If the service center's staff is OK, they will easily recreate your IMEI without much efforts.

Check user nokia8260's method in the link from salesale.
He does some edit on /efs/imei/mps_code.dat to match CSC.
Not sure if you need to flash a stock ROM + 512.pit + rooted kernel to establish a basic filesystem.

Just restore your phone to official firmware and call Samsung, tell them your phone doesn't recognize your similar card anymore and can't make or receive calls or text, thats what I did when i messed up my efs on my galaxy s 4g and i got it back within 2 weeks.

[Fixed by claiming warranty] Note 2 N7100 EFS partition corrupt :(

Well something went really wrong and i have a corrupt IMEI/EFS partition.
so i followed this and this threads to restore my EFS partition.
But for some reason, my IMEI number / EFS partition is not being restored. Also my mobile network (not able to make and receive calls/ no mobile data) is not working.
Please help ASAP My N7100 is still under warranty but i tripped the knox counter.
Also i am able to go into bootloader mode but odin is not recognizing the device. I installed kies and it is updated.
edit - flashed official stock rom via mobile odin so that i can take it to samsung service centre. But as a last resort, still searching for methods to restore efs.
If anybody still has any suggestions or help, please please comment here.
Thank you vry much,..

i tried this tool but its not working..
the tool shows that there is some data transfer, but nothing is happening in my phone.
just to confirm..how much is the size of a properly working efs.img file ?
mine is around 20,048 Kb

It's 20 mb the image, besides I doubt that you can do anything without a XwZ BOX,which will cost you over $100 so my advice is that you take it to a dealer for a repair , that's if you don't have an EFS back up, however I'm not sure if the things are easier if you have a back up either, since it didn't work for me.

Just a question... How did you make the efs backup you have? Size should be correct
If you remember how did you make backup, it'd be easier...
Have you got just a backup? The file you're using could be a corrupted file...

Yes the dealers can fix it, will cost somewhere between $30 To $40,at least that's the way the things are where I live. That is why I'm gonna keep my Note II on 4.1.2 until it dies away and will get THIS biggi and forget about Samsung alltogether,I have learned my lesson the hard way..

No one is gonna give you their EFS, as it contains their IMEI data.. and besides, you don't need an EFS back up, reflash your stock firmware via Odin before you do anything and make sure you have the correct file. Then turn your phone OFF and read every single stickie thread about how to flash/root etc or you WILL end up with a beautiful Samsung paperweight due to yourself not taking the time to understand how these devices actually work.
If you can reach download mode, you can get into recovery, you have READ how to do this correct?? - If not, I suggest you go do so.

If your EFS folder is deleted/corrupted and you can`t recover it (backup) you need a new motherboard with a new EFS folder. You can`t transfer EFS files from other phones as stated here allready.

Not strictly true, the Note 3 has an inbuilt feature where it can auto build the EFS using a fire script (as used by many including myself by firassuman) also if that fails THIS has been proven to work.

Samsung have done one thing right lol, made their devices virtually unbrickable and (easily) recoverable for once, so all is not bad with them really.

Hi
I don't know if you've fixed your issue with your g900v or not, but i have the same problem and the same phone and obviously the same symptoms ...
As far as I've tried, nothing worked not ODIN flashing ROMs, or QPST to write IMEI or EFS professtiona ADB .... etc.
What I've come to know is this :
1- keep the phone in a safe place till next months reveal a solution through developers here or elsewhere.
2- Flash the Original Samsung Verizon Rom ( Full Package with efs and bootloader mounts and all partitions " Clean Flash" ) which costs about 100$ .
3- Change the board for a (200$) new one .
So, I would try to pay the 100$ and flash the original ROM, and comeback to tell if it solved the Problem.
I wish if you share any different approach or feedback . I would love to hear it .
Bye

It could possibly be that your EFS folder is damaged. This is where your IMEI and Baseband info is stored. If that's the case for your device, these steps should work. I've done this on two phones (one being an S5) and it fixed this problem.
I'm assuming that you're rooted. If not then you'll need to root your device first. And you need to have debugging enabled. What this does is backups the files from the EFS folder, repairs the partition tables, then restores the files to the repaired folder.
1. Connect the phone to your computer. (Windows)
2. Download this: https://www.dropbox.com/s/v2h5dzisjd0rgj5/EFS_Professional_2.1.73_Release.zip?dl=0
3. Extract and run the program
4. Click EFS Professional... It will open a window showing that it found your phone
5. Click on the Backup Tab and make sure all of the partitions are checked, and your Device Filter is recognized
6. Hit the Backup button to backup the EFS folder
7. After that's done, click the Restore button and it will restore your files to the EFS folder.
I hope this helps you.

There used to be a tool for the Note 2 I believe, maybe S4, that would let you re-write your EFS if it accidentally got erased. Not a backup/restore deal, but a tool to key in your IMEI and it would write it to the phone. Maybe research that tool for a fix?

Was it a tool specifically for the Note 2, or multiple Samsung devices, or maybe a universal program like CDMA Workshop? I love that program. It's what I use when it comes to actually entirely rewriting files like this. Most of the time a full rewrite isn't needed though if the EFS folder has just been damaged. Which "damaged" is totally the wrong word here, but that's what it's called for some reason. I really don't even know how it happens, but I do know when it does, it usually just jumbles and/or fragments the info in the folder and needs to be put back in it's correct order. Kind of like defragging in Windows. Just a tool like you're talking about would definitely be cool for me to have though. I shall start my quest to find it. Lol

Please some help
Any luck yet ???
Got the same issue here, and none of the threads here worked .

Same problem
Hello,
I have the exact same problem. I bought the phone here in Mexico, and the phone came with erased EFS folder. Phone restarts automatically when screen turns off. When I'm using the phone, it works just fine, but some seconds after screen goes off, phone restarts automatically. EFS folder is messed up, I've tried out a lot EFS restoring tools with no luck.
I tried QPST but it does not detect the phone, only appears "?" and "No phone" blinking. The same happens with DFS Tool.
I will try to look for that tool joshw0000 talks about.
I hope we can find out a solution for this excellent phone.
Bye.

Hey ...
I did a factory reset and cache wipe, and now the phone stopped restarting when the screen goes off, but still got the "Unknown" issues.
But at least I got rid of the annoying restarts.
570 ppl read this and still no answer, I got to admit ... it's tough.

I originally used Qualcomm NV Tools to read the SPC Code,
then i went into ADB shell & did su + setprop ril.MSL 123456, it worked fine, and the phone started good, but still no MSL / SPC Code, also used MSL Reader but didn't work. Also it didn't ask for root permissions.
Click to expand...

Then here problems come. A red screen of death appears.
I tried using my USB Jig (even if download mode works without) to put the phone in download mode,
it worked, then connected to the computer using its original USB cable, before using Odin.
I though there could be a difference between "Factory" and "Odin" mode.
Used Odin version is 3.07 : The one that comes with "T Flash, Flash Lock, Nand Erase All".

I thought it was an efs problem. But how could i flash efs if totoro.pit comes with an EFS partition that doesn't have an img file? (the --11 Entry EFS without Image flash name).
I used PIT Magic (part of EFS Pro) to insert "efs.rfs" in Flash Name + FOTA, saved the file.
Click to expand...
Click to collapse
I checked re-partition and selected the totoro.pit file, i also've written "PhoneEnable=1" in Odin3.ini to use Phone Bootloader Update feature.
I inserted the Bootloader, PDA, Modem, & CSC Files. I checked Phone Bootloader Update.
The flash was fine, & efs.rfs (my most recent EFS backup image) flashed correctly into phone's.
Click to expand...
Click to collapse
But the phone still shows the red screen. I think the red screen is caused by "setprop ril.MSL 123456",
as i used qualcomm NV Tools many times and phone always worked fine.

The efs partition is usually not mountable in a galaxy y
Remove the sd card from your phone
Go into download mode
Flash the firmware from my firmware thread (links in my signature)
Never flash a pit file or bootloader - if you choose the wrong one you will brick your phone as you have discovered
If you can't successfully boot the phone after that you will have to flash the correct bootloader via a jtag - if you don't have one goto a repair shop as they cost about £200 UK pounds
If after that it still doesn't work might have to replace motherboard but you might as well put the money towards a new phone

Hi marcussmith2626,
I flashed Bootloader in the s5360 ODD package and used totoro.pit file

I took an hex editor and started the phone in download mode,
i took totoro.pit and added cal.bin under 'cal' partition name, and flashed custom pit.
(restarted and made a custom odin package with this cal.bin).
then i sent my latest cal backup (call this EFS Backup) and sent to device my cal.bin inside TAR file.
Then the phone restarted without problems.
Do you have an EFS (in fact cal) backup of your phone?
It's the bml15 block of your device. :good:
