Hi,
I got my phone abroad Galaxy S passport records, and I'm tired of you had your 3 months after using the version of Froyo MIUI I decided to install. I installed 3 days ago but I did not know what happened to the EFS. And now the phone's IMEI number 40000 0049990. .. this was not the original. phone line is running, but canceled. now what should I do to return the old IMEI number, or Waiting for your help Thank you in advance masters.
I have no idea what you're saying, but if you're having problems with your IMEI, then just search for "IMEI" and the first 5 or so articles might be what you're looking for.
this problem. MIUI for downloading the IMEI number has changed. What should I do now, and I have no idea
If you don't have a backup of the efs-folder you are screwed. Phone needs a new mainboard.

flash back to a stock firmware using ODIN, and you'll get the IMEI back
Download a firmware from samfirmware.com for your phone, flash it with odin, if it doesn't work with the firmware with 3 files (pda,modem and csc) try another with one file (like "JVH_JV3_JPO.tar") and your imei should be restored.
After, install root explorer and copy efs folder to sdcard and after on your computer. Keep it safe in case you will need it later.
Reflash an official froyo firmware using ODIN and you should be up and running, had the same problem when i tried MIUI a while back and thats how i got it sorted.
Hope it works out for you
flash to base
flash to base and after that flash to the new rom and look at the RE in the odin pro
It is possible to get the IMEI back? Super.

Restore IMEI with Backup
Hello I also have a problem with my IMEI. I flashed the latest miui version but backed up my efs folder like it was described by the miui-team.
Now I want to restore my old and original IMEI but don't know how to.
Hope you can help me and I know it must be really easy for you.
Greetings from Hamburg,GER

All I had to do was to copy the nv_data.bin and nv_data.bin.md5 files from the backup back to the /efs folder on the phone and reboot.

What is EFS
This part of the device contains some important and some basic info related to our device identity like Bluetooth MAC address, wireless devices MAC addresses, product code (also in the nv_data.bin) and the very main IMEI address (nv_data.bin), programming parameters for the device such as your account information (phone number, etc), data provisioning parameters, and a whole bunch of other things. So you can guess it's will be different for each device and one can't use others.
How it can corrupt :
- Any bad flashing, mishandling system modification can cause this.
- Also It can be corrupted by downgrading stock ROM. If you flash any old ROM (older to first ME6) on newer ROM (ME6 or any other rom released after ME6) it can corrupt EFS. Basically newer ROM believed to have new kernel that changes EFS data which older Modems can't read and results to fail in reading IMEI.
Impact on device/How I know I have corrupted EFS
When there is EFS partition is corrupted, device loses IMEI and due to this device can't gets connected to network. Baseband info also sometimes shows unknown.
-Check your IMEI in setting / by dialling *#06# if it is null OR if it starts with 0049** then IMEI is generic and corrupted. In Normal case IMEI which you can see in device setting or dialing *#06# is exactly same you can see on bill/box/sticker under battery compartment
-If you are unable to connect to network in spite of correct IMEI, chance are
A. Your device is Locked to specific Network OR
B. Your device is banned due to tempered IMEI
-If your AP,CP,CSC all are correct and even you are getting error (unknown CSC XXX) on kies update, it may be due to corrupt Product code in EFS. Read This for detail.
What care should i take
Before flashing anything, first thing you should do is to make EFS backup. Every person who have rooted device should make EFS backup earliest and place it to safer place on PC and /Cloud.
If you are on older ROM, make EFS backup on older ROM as well make another after upgrading ROM too.
If you have already updated to newer ROM, make backup on current ROM.
Here is different common methods for EFS Backup/Restore [There are hundreds of tools available on play store and don't use blindly, as unsupported tool can cause EFS partition failed to mount and to recover it need to use adb shell and more. Better use one of the below mentioned time tested tools]
You must have device rooted. Read post #2 of this thread, how to root Note2
you can use any of method said below.
1.With Aroma installer - No need to have PC, need CWM/TWRP installed. Here is Other Tool I recommend to must have for Newbies, Which also have many other options.
2.From Device itself - No need of PC, just requires installing application from play store.
3.Philz recovery - Also you can find this option on other CWM/TWRP, but i have tested only this.
4.EFS Backup/Restore Tool - you needs to use PC to work this.
How to recover lost IMEI that happens with downgrading ROM
If you have lost IMEI just by downgrading (as said by above by flashing older ROM), still you can recover IMEI without having EFS backup.
-Again upgrade ROM will restore IMEI OR
-Flash latest Modem. You can find it here.. You can download MG1 modem and flash using PC Odin with 'Phone' tab instead of PDA.
Remember above said works only if IMEI is corrupted by downgrading ROM only, if it was corrupted by other things, this won't be helpful.
Also Read This, if you have issue restoring EFS OR device stuck to factory mod.
Hope this will find helpful to all newbies regarding question about EFS and IMEI problem. I have posted this to general section so newbie can post to it if they have any queries.

The EFS image backup has proved to be immensely helpful all the way with the Terminal emulator!:good:
Please confirm: can the EFS backup image be flashed with Philz Recovery as an alternative to the Terminal emulator?

Please help!!!
You need to mention how does it happen in Details.
How does happend it, i mean what did you flashed? And what rom you had when you flash it.
Do you have efs backup?

Hi Dr. Ketan,
No I don;t have EFS backup and till today flashed many times but not faced any problem like this.
I recently flashed PRobam rom which works on 4.3 android and later return back to my region flashing CWM recovery. Later i tried toolkit for note 2 and tried mod for camera HD.But later come to know that toolkit has no support for my rom.
I think i lost my IMEI while flashing Probam but using wrong baseband trough toolkit can also be problem.No so sure.
Tried to go back on regional rom by different methods but no success.
Thanks!!
Basically it happens if you flash older kernel (it may happened by wrong selection in toolkit)
Reflash latest modem and try.
Just want to get this straight into my head here before I go diving into flashing a ROM sorry for being silly I just like to get it clear lol
Ok my phone is on DME6 so that means I can't flash any samsung based custom ROM that is using a version lower than that yes? but AOSP ROM's don't matter as they don't use the modem so won't corrupt the EFS correct? I am aware that for the SIII there was a flashable zip you can use to make the modem the newer one for flashing older firmware custom ROMS is there one for this? I want to flash this ROM or the HD revolution ROM (HD rev showing an older version in the title) mainly want a custom stock ROM that gets rid of that pesky SMS conversion thing
Thanks for your time
You have already flashed ME6 so you will have latest modem so yes flashiung older ROM you will lose IMEI. regarding AOSP ROM i am not sure, i have never used any AOSP ROM and not following so not familiar with that.
1.Make EFS backup Use one of the tool mentioned in OP)
2.Flash desired ROM, if you select older ROM and lose IMEI, you can find latest modem from my All in one thread (look signature) post #7. simply extract and use modem.tar.md5 to flash with 'Phone' tab (Not PDA) of Odin.
yeah I made a backup of the EFS (on the ME6 version not the older as this is how i got the phone) so I can use any stock based ROM as long as i flash that modem? think i'll probably stay with a ROM labeled as ME6 anyway to keep it easier on myself

Sounds like your IMEI has been blocked, youmay need to revisit the shop/person you bought it from.

If you have it then find a repair shop with an octopus box, they can rewrite it.

No-one here will tell you how to do it with a step by step guide as it is illegal in most countries.
If the IMEI is blocked and you bought it from a shop then take it back...
If you bought from someone then you have a phone that's been reported stolen and/or has been replaced by insurance. Either of these thing can get you in trouble with he law as you are using stolen property (it is the insurance companies property if replaced under insurance).
Good luck. But seriously, I wouldn't stuff around with it as you may get in big trouble... Get your money back...
Hi.
It is weared that after a factory reset you lost your IMEI. this is written in the efs partition in the root of your phone and usually gets lost if u flash custom roms.
Have u unrooted your phone and install any rom right after that factory reset?
If u r rooted, install x-plorer and look if u have any backup of your efs folder. There are some methods to restore and first save your efs partition. That is the the place where your IMEI, ip, serial no, Bluetooth and wireless no. are written. Without this u can not use your phone with your network.
I had the similar problem with my s3 and very hardly restored my IMEI. On xda are a lot of methods about this, and on other forums. For me it took 2 weeks of searching and I finally did it with a method but at least I had a efs partition saved. There are methods how to do it if u do not have efs saved but not all will work.
Try this steps:
1.If u never rooted your phone u might go back to the shop for repair.
2.if u are rooted u can flash back the stock rom, stock recovery, use Triangle Away that u can find for free on xda to reset the counter of your device to 0 so u get back your warrantee and bring it back to repair.
3.if u want to try for your own just search on xda and in Internet(youtube) about restoring imei.
4.There is a guy from Poland that can restore it through team viewer for 10 euros,if your model do not require a special cable. U can find him on xda or I might give u link but I am not home yet.
5.there is a program to install on your Windows that allows you to rewrite your IMEI in the phone but if u write another imei is illegal. I could not do it just bcs my windows 7 do not recognize the ports in device manager so neither the program could not see the phone connected even if in my computer I could see it.
6.u may try to go to a normal repairing shop to restore imei. They have that cable and a small electronic device and with a click they restore it. In Bruxelles cost me 45euros but in London and US they say is about 10-20 DOLLARS or Pounds.
I wrote u a lot but let me know in which stage u r.

I am using using the RAZR M on AT&T but my IMEI shows 0. I think I messed something up when flashing ROMs. Is there a way I can get my IMEI back? Please help! Thanks.
EDIT: Can someone at least provide insight into what partition the IMEI is located in, or the location of the NVRAM?

hopefully at some point you made a full nandroid backup, including "efs". if so, just restore the efs portion and it should be fixed.
if you dont have this backup, i cant help.
hi dudes
well i was playing with the phone and i lost the imei ans serial i didnot make a back up of the EFS folder so any ideas how to restore?
i try using kies no luck
i try using z3x box repair efs but no luck
if some one has this model and can share the serial file so i can edite and use my original serial and mask the imei with xposed apps it be great so i can get back my phone to service.
Maybe try this, at your own risk of course.

Be sure you know what you're doing though or you could make it worse. Be sure to ask questions on that thread if you're unsure of anything. Maybe read the comments before attempting too as others may have better solutions.
