Damaged EFS Partition? - Galaxy S6 Edge Q&A, Help & Troubleshooting

Hi All, I have a Problem. I have Ruined my Edge. Genius.
I have some how (read: Messed about with incomplete ROMS) damaged/Repartitioned my EFS partition. I can boot into the device and I HAVE an EFS folder with files in it, but still an IMEI 3500000000000000000000 or similar as well as no signal.
I know Its stupid, even more so to not have a backup, so you don't need to remind me, but any ideas on rectifying this? I know some people have had to get a new Motherboard installed when the EFS partition is missing or empty, but mine is there. I'm hoping something can be done. Maybe a .PIT file? I dunno....
TO NOTE:
I HAVE tried Smartswitch. NO, It didn't work :laugh:
Any help would be Apprectiated

No Signal, Can't Flash Any Firmware !

Hello, I own Galaxy S2, after I tried to update firmware to JPKI1 ( Downloaded from samfirmware), the flash went ok but after that, I noticed the Signal is gone, IMEI and I CANT do any reflashing either to stock or custom, I used ODIN to do the flashing procedure, each time I flash a Firmware nothing happens the old (JPKI1) version still there, I'm confused what to do now DIY or Service center?.
Regards.
sounds like you may have nuked your efs folder.
If you ment to write I noticed the Signal is gone and the IMEI
Hopefully you have a backup

Can you flash a new rom & rooted kernel via odin
then look to see what you have in /efs
If you have any backup files under /efs, say /efs/_nvdata.bak you may be in luck (I was)

Well, I tried to flash another kernel and another rom but the weird thing is after finishing the flashing, nothing happens at all, the old version is there, even if i do a data wipe, the data doesn't wipe at all, every thing is still the same, thanks for the reply.
BTW: I haven't found anything in efs folder.

Restore IMEI

Hi All,
I don't usually post anything but I use XDA a lot as it has helped me in numerous ways...
I would like to ask if anyone can confirm that by doing the below I can re-enter my IMEI in my S3...
1. From Terminal Emulator type "su" to gain root permissions.
2. echo 'AT+EGMR=1,7,"Type your IMEI here"' >/dev/pttycmd1
3. Press enter and reboot.
Can anyone confirm?
On an S3? I doubt it very much indeed.
What have you done to change your ime

I have't done anything to the phone yet, I will flash a different ROM soon and from my research I find that once people flash a ROM their IMEI might change which then impairs the phone from connecting to a network.
I want to be prepared in case I need to restore my IMEI. I have read of way that you can back up the efs folder and this is something I am investigating.
But, I want to have a back up plan in case I need something more.
Do you know of the above process? I have seen you tube videos and it seems to work, although I am unaware if this will work on my Galaxy S3.
Can you or anybody else confirm if they know this process to have worked?
If you take a backup of your efs folder then you're covered for this problem

Very rare for you to lose your IMEI .
EFS backup should be all you need .

Not so rare. I loaded CM10 and when I was done, so was my IMEI. This should be preventable. Yes, I think I can recover because i have a copy of my NV_data.bin file, but doesn't seem like a very sporting thing to do to a person just because they loaded a firmware.

I said very rare from the thousands of flashes on XDA few lose IMEI and 99% of those are total noobs . Plus 99% of those that do lose IMEI have not bothered to read and learn but just blindly flashed with no backup of EFS .
Flashing firmware has never been risk free .

[Q] GT-I9300 EFS Folder empty / No IMEI

Hello,
i'm new here in this forum and my english isn't that good but i hope
that someone of you can help me
I bricked my S3 two weeks ago while using swapper 2 and flashing some roms...
after a while the efs folder couldnt be mounted E: failed to mount efs (invalid argument)
and hanging in a bootloop..
My biggest fault was that I have not a backup of the EFS folder. Only
an complete Backup with CWM. But that couldnt helped me.
After trying a lot of Roms I got my phone with the I9300XXALE9_I9300OJVALE9_TMC and GT-I9300_mx_20120329 pit back to boot
normally. Android Version is 4.0.4
The Problem is that the EFS Folder is completly empty and I havent an
IMEI, so no mobile connections. But Wlan worked at home.
By the way: When i try to restore the cwm backup it will hang in a bootloop again.
Is there any way to restore the IMEI / EFS without an Backup?
I red that some persons could restore it with an other stock rom?
I'm not sure which Stock-Rom (4.1.2 probably but which exactly) I need for my Phone.
I bought it at May/13 in Germany (I'm from germany).
Galaxy S3 GT-I9300 16GB White
with 4.1.2 Jelly Bean Stock Rom
Do you need some more informations?
And please dont tell me that I'm silly, i know it already
Hope you understand my problem and maybe can help.
Kind Regards
Justin

If you follow the restore to stock guides, you may be covered under warranty. Cost of repair is minimal.
You might want to check this method for not efs backed up people...

Hello again,
sorry i had no internet access the last days.
Everytime when i try to flash a 4.1.2 Rom I'm stucked in a bootloop again :/ I'm pretty sure that I've choosen the correct Firmware.
Do you know what the problem could be?
I've not given up trying to repair my phone
Maybe my issue could be solved when I flash back to FW which was installed before.
The latest firmware is the
PDA: I9300XXEMG4
CSC: I9300DBTEMG3
MODEM: I9300XXEMG4
(Yes i know about the new efs format)
but this isn't working too.
Do you know why why I'm not getting at least a default IMEI? My Imei is always null/null
I've read about NV-items_reader_writer and qpst. Could they help me?
Greetings

Did you flashed the rom for your country? If not, look for your IMEI and see if it is corrupted, maybe it is the problem but im not sure, cause i never experienced having such problem.
I just checked. IMEI does not match the original imei. How can I solve? LG E450f

I never experienced such issue, but i have researched about the restoring process of the lost or corrupted IMEI. Do you have nandroid backup? If yes, restore your phone thru it. If you dont have any backups, try flashing to stock rom. If none of this works, it will be a lil bit complicated but there's still chance. They all say you have to backup the EMS folder before you can restore it if a problem with our imei occurs. Yet there was one solution i saw for recovering imei without the backup but it includes using the pc. I cant post the exact link right now cause im not yet at home. But you can search for it tho (it will appear easily). Im just telling you that there still a chance to fix it. Next time try to make nandroid backups and backup your IMEI first before flashing or changing something to your system, make it a must just a note: in our LG phones, as far as I know, we dont have the EFS folder(where imei rests) not like any android wherein they have that folder, but we can backup that imei thru an app LG BACKUP IMEI. Search for it, it will give you 3 .img files needed for restoration of imei and it contains of course the backedup imei.
If i helped, just press the thanks button for me and i really hope i helped you.
Cheers man.

Same here (Think we done the same thing with the Marshmallow 6.0.1 leak) I backed up, but the new version of TWRP I have has EFS as a separate option, I never even noticed and never backed it up.
However I Flash with smartswitch, and after reflashing the bootloader with odin and a Root Kernel, I can boot into the device and using root explorer, I CAN see my EFS folder. I deleted the .nv_data.bin files and changed the .nv_data.bak to .nv_data.bin (was an older date) and I now have the network options back but a generic IMEI and can't register on a network.
I feel SO close to getting it up and running, but if smartswitch can't help, not fully anyway, I'm not 100% I can be rescued either.

I've called to my local service center and they said that they will reflash firmware fo 450 CZK (about 17 euros) and It will be done in 1 hour 30 minutes. So I will se what they can do with it. I've tried everything... and right now I don't know what else I can do. But If you figurate out how to fix it let me know Thanks!
Ive also heard that if you flashing each partion one at a time with odin that has fixed it for some

I got 3 old smartswitch backup and i find a file with the imei and everything , do you think its possible to backup this files ?
You CAN recover your phone with smartswitch, there is an emergency recovery function with a IMEI and SN input option, some users who used the same threat (android 6.0.1) and has lost their efs partition reported that smartswitch worked.
I've done this procedure too for some weeks to recover my phone an everything is working fine.
possibly with root explorer
