So.. EFS folder contain the IMEI of the phone, so I do not think s.b. want to give his own IMEI to s.b. else
Better tell us what is the problem you have and how you get this problem.

After some accident my phone got bricked. and i try every thing to fix it.
after few tries i manage to install CWMR and after that i install CM rom. but i can't install any rom beside that. If i try it will stuck on LG logo.
And My efs folder is gone and no backup.
to do this ( http://forum.xda-developers.com/show...php?p=27912354 ) i need to go to Stock rom. But because of that Logo thing i can't do that.
And one more thing This is the worst phone i ever seen.. And It bricked when restarting. I lost my IMEI in SGS and in SGS2 within 2hr i got my correct IMEI without any problem.
If any one can give me a correct EFS folder I can give my phone IMEI and S/N to create it.

Follow THIS guide STEP by STEP. You will restore your phone, IMEI, etc... It is LONG but good.... there is many other guides that you can use too like THIS one that is more easy and fast. They will restore all. After that you can install some custom ICS rom

Hey,
The instructions give pretty clear details on how to back up your IMEI number. Just to reiterate the instructions in the link you posted, you're trying to back up your EFS. You can do so by using TWRP. Don't forget to store the zip somewhere besides in your phone. To restore your EFS, flash the zip file you backed up (assuming that you finished installing the custom ROM and whatnot).
Hope I helped and good luck!

The modems are different versions of the software that your phone uses to control the radio hardware. You should almost never manually flash a modem unless you really know what you're doing. It's mostly for troubleshooting, and even then it's the last thing you should flash.
You should backup the EFS partition in TWRP, as that is the part that contains your IMEI and such, and back it up to your PC. Flashing certain things can wipe the EFS and, since every device's EFS is unique, there is no way to restore it unless you have a backup you made stored somewhere safe.
Hi,
After installing a custom ROM, the IMEI reported by Android is different from the one on the sticker under the battery.
I believe the IMEI is somewhere in the 'efs' folder, but where exactly? There are all sorts of files and folders in that folder.
There is even a folder called 'imei', but it contains just one file called 'mps-code.dat', and that is only three bytes long, which isn't enough to contain the 15-digit IMEI.
Can anyone help?
Thanks,
Steve

It's inside the efs folder in the root of your phone.
Backing it up eh?

No, my phone stopped working and I think it's because the IMEI has got corrupted when I was messing with various custom ROMs - it no longer matches the sticker. I want to figure out a way to fix it - I can't bear the thought that I've just bricked a fine phone that I paid good money for.
Where in the efs folder? There are loads of files and folders in there.
Thanks,
Steve
Wait wait,
You can't text or connect to the network?
Try flashing a official firmware and see if the IMEI matches...
It's not that simple to modify your IMEI n.o, special softwares are required to do this.... It's stored in .nv_data
Don't you have any efs backups?
IMEI getting corrupt is seen many times in s3 and note 2 devices....
And also, modifying your iMEi is illegal, but people out there use a software to do it.... May not be good to discuss this software here...
And one more thing, does your phone shows a generic IMEI number when you dial *#06* ?

Thanks for replying, eatsleep. That's right - the whole phone works fine. It will see all the mobile networks in my area, and will register itself on mine (O2-UK). The only thing that doesn't work is voice telephony, SMS, and mobile data.

Here I must admit to being a bloody fool. I didn't know what I was doing and messed about stupidly in CWM, mounting and unmounting, deleting, reformatting, and so on. Basically I was trying to follow several guides at the same time, and made a total mess of it.
And no, I didn't know about backing up the efs before I started.

Not a generic one. It's really weird, because it's almost but not quite the same:
Sticker inside phone:
xxxxxx05861xxx3
*#06#:
xxxxxx05681xxx1
The ...86... has reversed to ...68... and the final 3 has become 1.
I'm an idiot and furious with myself.
Thanks again for any help you can give, though.
Steve
Wow! I've just seen how much it costs to buy that eight-tentacled device who's name shall not be mentioned.
$135 makes poor sense if it's only going to be used once. Perhaps the best idea is to check my local phone repairers until I find one who has the device?
Steve
Bumpety bump just this once:
Any chance of correcting the IMEI myself?
Thanks,
Steve

Hey babe..... please remove both of your IMEIs from here and never post them again in public. I'll post back in some time.... and your IMEI looks quite fine to me but still, lemme look for some time
And, your phone is not bricked, you've just got a bad IMEI

Can't find some content for your device but please do one last precaution before following any more tutorials, backup your efs folder and place it in a safe place.......
If you don't find anything, I can provide you with some guides for s3 (my device ) but don't know if they'll work for you....
One advice, reset your phone and send it to any service center.... They may charge you if you are out of warranty.....
here is a random thread i found but I have a bad feeling about the person.... Carry on at your own risk but back up your current efs, it may be recoverable but can move to a unrecoverable state after some repair attempts so, we can have hope....

Thank you again, eatsleep! I really appreciate your continuing help.
I've gone about as deeply into this as I think I can, without trying even more bits of dodgy software from around the web which might make the situation worse. So, I think my next step should be to take it to a reputable service centre on a no-fix-no-fee basis. If they can't fix it either, then I'll regard it as a write-off and - on the grounds that there is nothing to lose - I'll have one last go with anything/everything I can find on the net.
Whatever the outcome I will report back so that others can benefit from my mistakes!
Thanks everyone who tried so hard to help - have a good weekend.

Yeah, samsung can definitely help you, but again, be sure to make a backup of current efs to get back if situation gets worse!
And if you fail, then we can try some softwares out there, which might me improper to discuss here, but leave that for only when everything fails....

Time to send it back to Samsung for a new board. That's if they have one. Other then that you can try flashing a compete stock rom but normally that doesn't happen.
You learned a lesson. Never restore a backup from a different device.

Without an IMEI/EFS backup that was created before doing this, you're not gonna find much of a solution for restoring the device.

Hi guys
recently bought a s6 from ebay which was frozen on S6 logo. Basically managed to clear cache and factory reset from recovery but that didn't work, anyway I DL the O2 firmware and odin and put it into download mode I get a fail on odin when trying to install the rom
The phone has knox 1 and also has red writing SW Rev. Check Fail. Device: 3 Binary: 1.
I'm unsure what to do and if theres any chance for me to recover.
Many thanks
Mav
it failed because you flashed an incompatible Firmware.
where did it stopped flashing in odin? In sboot.bin?
If thats the case, you need to download proper firmware/country for your device.
Let me know what country is ur fone made of.
Hi thanks for your reply.
I managed to get it working by installing root and unikernel, it boots into O2 the firmwarw is 5.1.1
Only problem now is imei is 3500000000006
And it wont make calls dont know if imei is corrupt ir they sold me a stolen or lost phone?
I may install tw recovery and custom rom and see if that works.
Any suggestions?
Hi
Ive managed to sort out and get it to work infact typing on it now. Its currently rooted custom rom and twrp. I e managed also to restore original imei number so overall im quite pleased with myslef lol.
Anyway one last problem i have is ive tried all sims but none work i know ita picking up signal as the bar shows top right. Also chexk my settings.
Ive tried automatically and manually going to register networks but it says unable to connect try again later. I know uts not my area as my wifes s6 works perfectly. Sim also def works. The phone also picks up when a new sim has been inserted so i dont think its sim slot.
Any ideas guys
OK new update if anyone can help I'd really appreciate.
Installed new vador rom Imei reverted back and serial number is all zeros
Is this something to do with baseband if so how can I fix read somewhere about ariza patch but that was s3 4 etc.
Thanks
Mav
1. Your EFS is corrupted. The IMEI you see is a generic one, phone will be useless for network provider only wifi will work.
2. The one thing that caused this is by flashing an old bootloader to your phone. Thats why youve encountered Check Fail error on Download mode.
Happened to me also but got it fixed in the end.
OK thanks for the info how do I fix? I do have my wife's s6 but that's not rooted and don't want to root can I restore the efs
Many thanks
Mav

I think I know one thread that has a firmware downloader with ultra fast download speed you may try searching it.
I dont know if it will help, but you may be able to successfully flash the firmware but many of those who have problems were unable to boot the phone due to corrupted efs data.
Here's my way of fixing it (if you still have intact efs). http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28
But if its already wiped, there's no way you can retrieve it unless bringing it to samsung or any repair shop.
Anyways, mine was fixed (IMEI) using Octopus box repair tool. Since I cant do anything to recover my generic imei.

As far as i know if your EFS partition is corrupt and you do not have a back up of the EFS partition to restore which you probably dont as you bought this as broken then sim capability is dead, im not sure of any other way to fix this unless you have the intact efs partition
Hi
How can I tell if the efs is corrupt it shows a baseband it now shows the correct ime I
It just won't connect to network it says try again.
I can post a screen print of efs folder on es Explorer if anyone knows what it should look like
Here are screen prints but I think I'm speaking to myself lol
Hi there i spent months on fixing issues like this (i now have a tool that takes care of all this) , best thing you can do is flash to a rom where the original imei came back do a backup of the efs, flash to a orginal rom ( latest rom) make sure its the right one for your device, connect to kies, install the rom again root and restore the efs failing that the imei is blocked use checkmend.com the uk version if your from the uk, message me if you need help

Your rom, recovery and kernel doesnt have to do with corrupted efs.
Only way is to bring it to repair service using box tools to re enter/validate your imei so that you can connect to your network provider. There is no other way around other than retrieving your efs and installing it or thru repair service.
You may now relax yourself at finding ways to connect, I assure it wont help trying to flash and flash and flash stuff to your phone.

Uhm can you send sms or make calls? It seems you have a valid Imei
Ok ive tried all stock roms including o2 and a uk btu one but no luck they all do the same thing get frozen on Samsung logo then I flash unikernel and it boots.
When checking my efs folder I can see no modem file I'm now wondering could that be the fault? so I downloaded modem and BL for 5.02 and 5.11 both will not flash via odin I get a fail message and on device check fail device: 3 binary: 1 messgage in red?????.
So I'm a little lost, I was wondering if I managed to root my wifes s6 which is virtually new could I back up her efs folder then copy it into mine and just amend the imei to my original would that work? also is there a way of rooting my wifes phone without triggering knox?
Any other suggestions guys I really don't know what bootloader was on it to start with or rom is there any way for me to find this out?, also another weird thing when the o2 uk roms install they install german apps?
Thanks guys
Ive repaired EFS Partitions with scripts downloaded from links at xda.
For example i trashed my EFS partition on my note 3 so it caused hard reboots after android booted up and it couldnt be fixed with anything else than the EFS partition repair scripts.
Edit: friend repaired his Note 4 also.
Thanks but where can I find these scripts as I've looked everywhere and if I did find how do I go about doing it. At the moment when I try to flash modem and bootloader it fails.

Hey everyone! I had flashed Lineage 14.1 on my Samsung J210F(https://forum.xda-developers.com/an...ageos-14-1-t3680656/post74433279#post74433279)
And everything was working perfectly until I wanted a file from the stock ROM. I flashed the stock ROM and after my work was done, I flashed Lineage again. Now in the middle of this flashing I lost my network. I tried changing the APN settings and even tried putting it on GSM Only but it's of no use. The network comes and goes abruptly. I even tried going back to the stock ROM but now it's the same over there too. My radio band and everything is as it is. I just can't figure out what's wrong. I have tried reflashing multiple times. There is no problem with the physical hardware or the sim as I have tried it with a different phone too. I haven't touched my efs file either.
Any suggestions would be appreciated!
Somebody please help. I just cant find any solution to this. I've been through each and every forum possible but I still cant find anything. IMEI and everything is normal. I did try to flash the stock rom and the stock rom receives network but as soon as I switch to custom rom, the network goes away. Please help

DoHave a look at your IMEI status with *#0011#
If it's NG you may have inadvertently corrupted your EFS partition. I dealt with that myself recently. If that's the case, if you've got a backup of the EFS, try to restore it. If not, backup your EFS to your PC or another secure external location, in case of worse emergency later. Then empty your EFS folder except for the FactoryApp and prov_data folders and their contents, then flash a clean firmware with Odin.
This can backfire. Read-up and Backup before proceeding.
I have no further expertise to offer. I just blundered out of messing up my EFS during flashing.

Yes I have backed it up before but this case isn't about that. I have the proper IMEI number. I'm just not getting signal and it's becoming really frustrating now.
I even tried going back to the stock ROM but I'm not getting any signal there either. Please see the picture attached

I seemed to have the proper IMEI, too, but it's status was NG anyway. Check *#0011# if you haven't yet, to verify.

*#0011# doesn't work for me but *#06# does and this is what it shows
If you can figure out how to get into servicemode on your device (which is what *#0011# does on my device) then you can check the IMEI status, or if you're confident you can restore the EFS partition try the method I described above.
Beyond that, I'm a virtual noob. My only counsel is to be patient and cautious. Someone with actual expertise may advise you yet in the sub-forum for your device or a thread discussing a similar problem.

The code for me for service mode is *#*#197328640#*#* but I can never get to open it. It just looks blank
There may be other ways to verify the IMEI Status, but that is beyond what I know. Someone more expert may have advice.

Also, I can find FactoryApp but I can't find prov_data folder. This is what my folder looks like. Can you send a picture of yours
If your backup is of your recent, working setup, it might be interesting to compare it to your current EFS. I have no suggestions as to how to inspect the contents of a backup.

I'm quite sure there's nothing wrong with the IMEI number. I have confirmed it multiple times. I just feel so helpless. I don't even get to know if someone's calling me. I just hope I can fix this ASAP

This is not a backup. This is the actual EFS folder. Anyways thanks for the help. I'll keep bumping till someone else sees it
Also I would like to add that the network sometimes bounces on and off after a reboot so..
My IMEI seemed correct as well. The problem was with something in the EFS partition which resulted in IMEI status NG, and I only discovered this was the issue after seeing the actual IMEI status assessment by the servicemode. I repeat: the IMEI numbers shown by *#06# didn't indicate anything was wrong.
Should you proceed along the path I suggested, make sure to flash a fresh firmware from Odin directly after. It seems to be required to restore the EFS after the procedure mentioned before.
Google "FactoryApp" and "prov_data" before proceeding.
Beyond that, good luck.

Btw I did try that code when I had flashed back the stock ROM and it showed IMEI Certificate PASS. I'm sure there's nothing really wrong here because as I said the network sometimes bumps on and off after reboot
I have a question what is the baseband number on the phone? My ROM hasn't been updated for sometime now and I have got official updates for the stock ROM. Does the new update for the stock ROM come with new baseband? Will flashing the update for the stock ROM update the baseband too? Or is that in the kernel? I've read that updating the baseband usually fixes network problems. Please help me fix mine
I just extracted the new update for the stock ROM but I couldn't find any modem.bin file in there. There's just usual system, recovery,etc. If I don't have the modem.bin file how can I flash the radio/baseband? Should I just flash the firmware via Odin through AP or CP option?
