I sold my s2 to someone.. the next day he told me that he was not able to call or receive calls.. he was getting a msg *sim card not registered*.. I told him to bring the phone to me.. I checked the imei it was replaced with 0044xxx0000 (something like that).. I downloaded es file explorer and checked there were no files in the efs folder of the phone.. so there is no option to recover imei from that.. is there any other way to recover efs folder/ imei no. (No I don't have efs folder backup, if I had, I would have solved this problem already)
please reply asap
thanks
If I remember correctly...
No efs backup of any kind = service centre

thanks for the quick reply. but its an unlocked imported phone with no bill and hence, no warranty. will they still re-write me a new imei no. if i will pay for it.?
I think they can do that.Some people over here restored it this way.At least try to ask them.
is the device rooted?

obviously it is..
Makes no difference if it is rooted or not. Take it to a local mobile repair shop (not Samsung service centre, they charge too much). Many have the equipment to re-write the IMEI to the device fairly cheaply.

Hi,
I've flashed my Galaxy ACE a few times and now i realized that when i try to see my IMEI it gives me 0000000000000000.
I've tried to look for /efs folder and the nv_data.bin file but they don't exist.
Is there anyway to recover/generate this file? I have no backups
Checking imei with *#06# ?
Your phone is bye bye. I am sorry for your loss.

What is weird is that i can still make calls and sms.
I only noticed that i had no IMEI because Viber became deactivated all the time, and i checked their foruns and saw that this behaviour was due to no IMEI.
Maybe it's better send your phone to tech.
Try to either remove the sim card or turn on the airplane mode.
I've burnt a sim card by flashin with odin. IMEI did show up if the above procedure was done.

take it to service/authorised care centre and just tell that the phone just couldn't boot one morning and act like "gsm noob". hope they will fix it then enjoy your Cooper
this method always works for me and my friends, for example Nokia service repaired my bricked n95, later they replaced new nobo in it. acting like a noob is cool :d

LOL is this a troll post?
Nothing you can do about lost IMEI. There's someone who managed to copy it between phones but then that makes his phone have another phone's imei so I guess it's not a good solution.

Can someone tell me if the /efs folder in Galaxy ACE is a partition mounted on /efs or a folder created on the / filesystem?
Also can someone provide me a zip with the contents of a Galaxy Ace /efs folder so i can try to modify the nv_data.bin to get my IMEI back, i have a friend that has a sptbox and i've eard that with a nv_data.bin file it's possible to change the IMEI.

Recover IMEI on the Galaxy S II and Other Samsung Devices in Nine Steps
credits to xda and vaskodagamma
Sometimes bad things happen and you don’t even know it. Flashing modules can wreck your WiFi, kernels can bork your camera and, and flashing some ROMs can mess with your EFS folder—and thus your IMEI—on Samsung devices including the popular Galaxy S II I9100.
XDA Forum Member vaskodogamagmail has posted about a method that may help users restore their IMEI if the all-important EFS folder is modified by accident. In a nut shell, restoring your backed up IMEI involves deleting the corrupted EFS folder, creating a new one, and doing a few file modifications with a root-enabled file explorer. In the words of the developer:
so I researched. searched all the forums and didn’t find anything that could cure my phone’s IMEI and set it to the original IMEI number. so I experimented and after some hours, I fixed my IMEI.
one thing that led me to the conclusion that ” .nv_data ” file is the thing that I need to fix the IMEI is that they share a very look alike name, and they have the same 2MB size.
While the guide was written with the Galaxy S II in mind, the method should work on all Samsung devices with EFS folders. Those looking to restore their IMEI should visit the original thread for additional information and the full method. Just be sure to back up your device, including the contents of your EFS folder, before getting started.
so head over to the thread

fool huh. this is an info, and just read the comments on that page and its not for someone who has fully lost imei.
Lol. it suggest to backup efs. In order to do so we need to mount the efs partition first. Doing so is the most common cause of lost imei in the first place.

okie.. Now those who hav lost there IMEI must be on Network locked rite?? As of in INDIA we dont hav these network locked phones much.. Only some providers gave some phones but these branded devices are rarely network locked.. So i checked my phone with Root explorer and also in recovery menu no file such named as EFS(encrypted file system) which mainly holds the IMEI.. May be these nw providers afraid that the person might change the IMEi..

EFS(encrypted file system) is for Microsoft.
Android /efs is different from EFS. And our method of storing imei is different from other Samsung devices. So the OP method Won't work.

EFS is not a folder btw its partition which is never mounted to use with some file explorer things as you can see how much loss you can get just by mounting this thing manually

Hello everyone, I've got a big problem... I have been using my SGSIII with CM10 and siyah kernel, and everything was fine. however, 2 days ago my phone froze and i had to pull the battery. after restarting i wasnt able to get a connection... i tried reflashing, rebooting, resetting and everything, but nothing worked. after looking around I saw that my device says Baseband: unknown and IMEI nothing... so i checked my efs folder with root explorer - and see it is empty. fortunately i've got a EFS backup! So i tried to recover it with HC-kTool - it says success however the efs folder ist still empty and stil cant connect. when I try to move the backed up files into the efs folder manually, it tells me that no space is free..?
I also checked "mount" in the terminal, and saw that the /efs partition is NOT mounted... so I remounted it manually with
Code:
mke2fs /dev/block/mmcblk0p1
mount -w -t ext4 /dev/block/mmcblk0p1 /efs
after doing this i can restore my backup and there are loads of files in the /efs folder! however, after a reboot everything is gone and /efs is not mounted anymore
does anyone know what i need to do? the phone is running stock ALE8 rooted.
Cheers

This information might be of use to you, but the restore without an *.img file (assuming you don't have one) probably won't be.
The last one (0p3)
Sent from my GT-I9300 using xda app-developers app
actually I have an .img file... called
Code:
efsdev-mmcblk0p1.img
which is around 4MB... thats an efs-backup made by SiyahKernel about a month ago.
I'll try it with this one!
That sounds like a plan
Don't do it ! Efs partition size is 20mb and is called 0p3.
If you do it, you'll screw up your efs partition (assuming it's still there).
Just try to mount 0p3 to /efs.
If it doesn't work and you don't have a 20Mb backup of 0p3, I'm afraid there's nothing more you can do to restore efs.

I'm not in need of one, my EFS is ok.
I was pointing out to Fekle in my earlier post that the EFS partition is 0p3.
ok, Thanks everyone, I just did it before it worked well, the efs folder is now "normal" again, my baseband is recognised and I can see my IMEI again, however it differs from the one written onto the device under the battery -___- my "real" imei is 3531..... but the device says 004999010640000 now in the settings
I think this is something like a stock fallback imei or sth like that.. any Idea how I can change that to my real imei?? that has to be possible somehow.. !
greets
This imei is generated when NV data is corrupted (meaning efs did NOT restore correctly). Do you want me to have a look at your 0p3 backup ?

I don't think sharing EFS data is a good idea. In most countries changing IMEI info is illegal - - access to someone elses EFS backup would probably allow you to do that.
Upto the OP though if he/she still wants to share it.

yes, that would be awesome... I just found a newer backup which is called ...0p3.. and is about 20 mb in size.. however restoring it doesnt work :/

Sharing publicly efs is indeed a bad idea, but not being able to use your phone anymore due to a corrupted efs is worse IMO. Anyway, I've build an app to sim unlock gs3, many users trusted me before and sent me their corrupted efs folder for me to have a look (which doesn't mean he has to ), so if I ever wanted to use another imei, I'd have plenty already

hi, would you be able to tell me the right contents of the /efs/imei folder? what files should be in it? i have a backup efs folder but i'm trying to figure out if it's a usable backup... and also, could you verify for me if /efs and /factory contain identical files? thanks a lot!
Ok Guys. This is the story, i was playing with kTool, then i hit "Format EFS"
The phone restarted itself and then failed to boot...
After a long 4 hours of research, i discovered that i had a EFS.img on my SDCard
The i said to myself "WOW i'm lucky!"
restored this image to my efs partition, it mounts correctly now but i seems to have the "Fake IMEI 004999010640000" problem.
Anyone have a spare efs.img available to i try it on my phone? Of course... From a bricked or not working anymore phone
My Galaxy SIII is the International I9300
I would love to have a new efs on my phone, i don't have original one =/
Sorry if it's illegal or against rules of the forum or in wrong place ^^
I don't know if this helps.. But...
I have attached an image of how my phone looks like
no, that's illegal
Why would that be illegal?
Sent from my SGH-I747 using xda app-developers app
because it would change the IMEI
Then i just lost my phone?
I'm asking a backup of a dead phone... Is that illegal? :S
you just lost your phone, yes.
but you said you had a backup, you might be doing something wrong. just don't ask for others people backups anymore
Take it too service centre, the imei is in the back of the phone, they should be able to reinstate if the phone isn't blocked
Is it possible to create or change efs data manually
I do not have a backup and my IMEI is wrong
I have contacted samsung about repair awaiting response
In the meantime my wife has the same phone from same provider network etc.
If i were to make a backup of her efs could i manually edit it to mine and restore
I realise this topic will most likely be removed for the fact it is essentially asking how to change and IMEI but this is only illegal if you are changing it to another on your phone i am not
I am trying to restore it to its original device
From what i have seen so far this is only possible using a z3x box or similar tool at a cost of £95 for the box alone
No you can't use her efs. And no bkup you will have to send to service centre. Yes z3x works but cost is probably to much for one fix. Go to local shop could be cheaper as most use this or similar
I9100/I9300
You can get the imei issue repaired at a phone shop for £20. What you're suggesting isn't legally possible outside of the repair industry (I.e at home).
Or send to samsung if you haven't voided warranty already who will repair for free

Ok thanks guys was just a thought i have a few local shops i may take it tomorrow to have a look
One more question is it still possible to backup efs on new MG4+ firmwares as it is a new format is it still supported
As in if i get it repaired then i can make a backup for future use
Once repaired it will be "back up able" and restorable...
Sent from my GT-I9300 using Tapatalk 4
Well i dropped it off at the shop this morning was advised it would cost £20 so i was happy with that
Now i just get a phone call asking if its ok to re-flash phone which im ok with as all my data is backed up
But re-flashing the phone is going to do nothing which leads me to believe this guy has no idea what he's doing.
Only thing i can think is that he cant access the IMEI under the MG4 structure and is flashing to a previous firmware
We will see
Well £20 down and my phone is back and working running UFMB3
Now i have made a backup using EFS Professional i should be safe to become flash happy again knowing i always have this to fall back on

Make a copy with ktool "app of playstore" make a copy with your recovery too and copy the efs folder completely and put it on an sdcard and put that in a safe place. Remember you can never have too many efs back ups. Glad you sorted it out :thumbup:

Good news. I recommend a few backups of efs. I have 3 at any one time.
If you want to use an mg modem without changing efs, theres a link in my thread. It also takes a backup of efs too.

I have made backups using efs pro and ktool and uploaded them to my dropbox what did notice about both apps is they make the backup on the internal memory which will most likely be wiped when installing a new ROM but esily moved
I do appreciate the help and advise been flashing phones for years now this was my first hic-cup.
I'll have a look at your thread rootSU but just to be clear
MG4+ uses alternative file stucture and location (currently unknown) for efs partion
If this problem was to re-occur all i would need to do is restore phone to a Baseband Prior to MG4+ UFMB3 for example and restore efs from backup
Should do the trick...
