Imei deleted

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.

Please BIG PROBLEM with 6.1 Lightening

This morning my friend give to me a gs2 new but i haven't read what version is.
But i started to download the new lightnening 6.1 and open Odin .
All seems to be correct but after the reboot the sim card dont work.
I try everything ! But the only way to use the phone is flashing by odin the KH3 firmware .
Can anyone tell me if i made some wrong thing ?
The gs2 can be rooted first ? no ?
i can flash the 6.1 lightening in every case or not ?
Thank's

Where do you live, what country?
Before you flashed with Odin, did you close Samsung Kies with windows taskmanager (Kies Trayagent and KiesPDLR )?

What the hell! I got the same problem today and I think i´m a quiet experienced user... Under "Baseband" there is just "Unkwown" stated I flashed manually Modems in Odin, restored a backup and tried it in a Stock-rom... This all happened after flashing the Frankenstein KH4.

Not wiped your IMEI i hope....

It seems that you lost your IMEI number. If you have backed up your /efs folder you can easily restore it. If not you might be able to get a generic IMEI which lets you use your phone again.
There are several threads here on xda and oder sites. There is even a youtube video how to restore your IMEI. Good luck.

My efs folder is backed up and still on my sdcard... I just have to overwrite the old efs folder right? Because i´ve done this and nothing changed. The phone is just completly ignoring my simcard (I also tried different simcards).
PS: And yes *#06# gives me an erased field

Flash back to stock KH3, root it, backup the /efs folder, flash Lite'ning and restore the /efs folder from the backup

I tried now almost everything! Flashed stock, flashed Lightning, restored backup folder and tried to restore a generic one with the youtube tutorial but everything does´nt help meto get rid the proplem with the undetected simcard...

One is your IMEI correct
Two have you flashed a clean stock rom ONLY
Three have you cleaned the sim card contacts and on the phone
Four dialling *#1234# are you showing the correct CSC.
Five are you getting a network connection when entering manual details of the network APN etc .
As you have broken a new phone within a day i suggest you take it to a service centre .
Follow that up by reading the guides before flashing as plainly you don't understand what you are doing .

I´ve just flashed stock KH4. The result was the gone IMEI! I own this device now since two months! Dude dont blame me for this... I´m just not able to restore my backed up IMEI.
My english is not the best but you're a real british guy and you have the possibility to write useful and understandable, particularly with this amount of posts.

Maybe your SGS2 was locked on some network. But.. if you erased EFS, you have to copy back all files and reboot phone. How did youo backe up /EFS? There is a HC-kTool app somwhere on XDA which can backup and restore EFS.
If you manage to restore EFS, run sgs2 sim unlock app to find unlock code (if its sim-locked)
You should explain how did you backup /efs and how did you tried to restore. Maybe restore procedure is not correct.

it´s an fully unlocked device. I have a tar packed backup of the efs folder on my sdcard, but can´t remember when and why I´ve done this. Until now I just overwrote the old efs folder with the original one (i´m not quite sure if it´s a real backup. Is there any way to find that out?) , but is it normal that I don´t even got an generic IMEI?

I had the exact problem with my cousin's SGS II, brand new phone on orange network, when I flashed Lite'ning rom 6.1, got no baseband and no IMEI, flash back to stock XXKH3 and everything fine. Problem for Mr Lite'ning to sort I think. Thing is my release SGS II runs it fine

Are you using International or US Galaxy S3 ?
Methods using Diag mode and software like SGS3-Exploiter-GeeK or QPST (Qualcomm Product Support Tools) are made to work ONLY with the United States variant of Galaxy S3 (based on Qualcomm SoC).
Now, I don't know software to fix International SGS3 without EFS folder backup (Sorry :crying: ) when nv_data.bin and .nv_data.bak are broken.

I had this problem on my S£ (international) a while back. It happened after flashing cm10, I had a generic IMEI code. I f'd around with it a bit using root explorer and the EFS folder and the .bak files but this did not work.
I tried ktools etc. nothing seemed to work..
oddly enough, i got it back by flashing back to the stock ics rom via Odin, since then my IMEI has been fine after flashing JB roms.
worth a try!

@lozfromcorby : I just saying they have not software to do that now on I9300. But I'm agree with you ! Sometimes, we can recover wrong IMEI when flahsing stock ROM.

Yep it's international ((
Ok I will try to flash stock rom again :/ I will post result here....

I have seen that the Z3X box can fix all Samsung Galaxy devices excepted SGS3 !
I think you need send your phone to repair center.
But before, you can try this :
Save remaining files contain on your EFS folder. For that, use EFS Tool Pro for example :
http://forum.xda-developers.com/showthread.php?t=1308546
Try this tutorial (with a full official stock firmware/kernel | Flash it with ODIN before trying repair) :
http://forum.xda-developers.com/showthread.php?t=1264021
Caution : DO IT ON YOUR OWN RISK.
If it doesn't work, you must :
- reset binary counter (with Chainfire tool : Triangleaway)
- perform total wipe data / wipe cache (from recovery mode)
- flash the latest stock firmware corresponding to your region
- verify the phone status : must be "Normal" and not "Modify".

Device is working... but no network thats why ((

Could you tell me which ics stock room version helped you recovering your imei?
Sent from my GT-I9300 using xda app-developers app

I have a temporary solution for you. if you still have the backup of the the EFS folder in your internal or external sd card than follow the following steps,
1. copy ALL the files from the EFS BACKUP FOLDER.
2. go to the root of your your phone with root explorer of ES file explorer and find the folder EFS. it should be with all the system folders like acct, config,data,dev,efs,etc so on and on.
3. now paste all the copied files in to EFS folder. tap on REPLACE THE FILES if ASKED...
4. close the app. and go to the home screen and wait for few seconds.
if your simcard have pin than it will ask the pin after few seconds and if it doesnt have any pin than it will just get the network.
good things is you have your IMEI number restored and can use the phone like regularly. NO PROBLEMS AT ALL. WITH NETWORK.
bad thing is NEVER LET YOUR PHONE SWITCH OFF. If it will switch off than you will have to follow all the steps again... annoying but works... let me know the progress buddy... best of luck...

Your other option is to to flash the stock rom but not let it finish. You will get a loop screen. Then just send it off for repair saying it doesn't turn on.. It will be diagnosed as a broken bootloader and fixed and the imei number will be back to the original. This happened with my old s1

[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,..

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.

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..

EFS missing files / IMEI and Baseband unknown

Hello guys, I need a lot of help was messing on the Internet from my Galaxy S5 G900M when he crashed and got warm,
I removed the battery called him but was no carrier signal after prsquisar discovered that my EFS is missing files:
.nv_core. bin
.nv_core.md5
.nv_data.bin
.nv_data.md5
.nv_state
I have little money when then pay for repairs to the box is in final plan at the time,
I researched many posts with repair attempts here Forums new and others over the Internet to 3 full days without success, what do you think is like me rebuild these 5 files on my device?
vi whose other older models (Galaxy S4) with a program, only it does not support my model!
Obs:
My S5 was before the problem with the Rom xXx No Limits 5.7 + Boeffla kernel + Root
I've tried to go back to several versions of the stock roms and did not work!
Thank you guys

I also have the same problem with my G900M
It would be very good for someone we help.
My friend, any progress tell me.

i dont want to bother or anythin, but for u to recover the efs file is more or less impossible.... the only way would be if u would have made a efs partition backup trough twrp, since i bet u didnt made one, ur phone is now more or less just a tablet with no usable phone stuff

Hope this helps! Best of luck

I have SM-G900F and in efs partition I don't have this files above too, but i have IMEI in phone and it works good. I think the Galaxy S5 have a special version of efs partition. I can send you my dump of efs part. (efs.bin file, maked by dd in adb in console on PC ) if you want. You can send me your dump of efs to compare this. It is surprise for me why I dont have the folder "sec_efs" like you.
