When did you unlock with freegee? If its after February you have efs backups in /sdcard/freegee automatically

Since IMEI spoofing is illegal in most country, the IMEI is most likely encrypted. I don't know how it is input on the Optimus G, but I had an issue back with my Galaxy S, and let me tell you, just hope you have a backup!!

this is terrible.. but with jtag i have to disassembly my phone?
is not for me..
other solution????

no. only JTAG or you have the internal LG IMEI repair tool

Hmm, I am coming from Samsung world and there flashing a Samsung ROM would always restore the IMEI, not the case with LG?

where can I found it????? in internet i don't found...

you cant find it. its INTERNAL

JTAG is a tool, made by RIFF, not just a software.Any respectable gsm service has one.Rewriting software with JTAG costs between 10 and 20 euros,depending on the phone.At least here in Romania it costs this much.Don't know other countries.
Bottom line, writing the IMEI it's not a DIY job.it can be done only with proper tools,on a specialised center.
I think there would be another way,but i'm not sure, you need to talk to shelnutt or autoprime to confirm or not.
If the EFS backup from other phone can be decompiled,and the IMEI section is find,change the existing imei on that backup with yours, recompile and restore it with freegeee.i repeat,this is just a theory.
Another question,what method did you use to unlock bootloader?

Even with a samsung, if you'd screwed the partitions real good, you'd lose everything, even the backup.

You can try it, but most likely not.
You would need to decrypt the file, replace with your IMEI and encrypt it. copy it and it "would" work, theorically.
OR, you could call your provider and ask them if they can do it. Might not be worth the hassle!

Yes I can resolve sending the phone in service...But my wife told me "don't to do that""
For me will a victory if I rewrite my Imei because in the future i will change new rom... and want learn how to...
how I can enter in Diag Mode?

you're not sending it for waranty, the "waranty" was void when you changed the rom. If your provider gets to know that they will void it "officialy".
You may contact the service to know if they can rewrite an EMEI, and ask them how much they charge for it.
The FIRST thing you should do before installing a custom rom is a backup of the EFS partition:
http://forum.xda-developers.com/showthread.php?t=2161611
or, if you have installed freeGee, you might already have a backup in the FreeGee folder in img format
If not, then you will need to open thoses .img, edit them with your IMEI and reflash them

Not that easy.i didn't find any tool to decompile those images into workable stuff.like i said,maybe you will find more help on irc channel.asking will not hurt

2) Change the Imei with my Imei number in Backup Folder .
I have to find a tool for change the number in the image...
thanks at all for the help... we will win..

Please HELP!!!

Hi guys,
I hope you pleeeease can help me I am desperate. Turns out today I Got a new N7100 because my old one was broken so the guarantee gave me a new one. When I returned home, i made a restore backup from my old phone into the new one and by muistake (stupid stupid mistake) I didn´t backup mi EFS folder, so now the phone is not working and giving me a generic IMEI....
Please tell me that there is a way to fix it without the EFS backup... I am just about to cry here
Thanks and sorry my bad english!

Try flashing a stock rom via odin. If that doesn't fix it you're screwed I'm afraid.

I always make backups of my EFS but I don't know exactly what it is for and how they work. If someone gives you a backup of their EFS will it work or is it related to the machine?

Well, I guess you need to flash back original Sammy ROM and bring it back to Samsung, no other choice. Sorry

Like above flash back your original stock rom. Pretty sure this is the only way.

Maybe this thread can help you..i think the OP of that thread face same problem like u did..lose imei no..

STILL NOOO HELP
Please me, i have lost my IMEI saying NULL / NULL and im getting not registered on error. I have not backed up ESF folder as well.
Struggling from last 5 days to fix it up. some how i got Modem_N7100XXDMG1 and flashed. After that i have got some fake IMEI.
Tried flashing STOCK ROM 4.4.2, but still no luck.
Read on some forum that MODEM of 4.1.2 or J.B 4.3 resolves this issue but when i try to downgrade from 4.4.2 to 4.3 via ODIN it straight away shows FAILS in RED
IM using Note N7100 K.K.4.4.2
PLEASE PLEASE PLEASE HELP ME.

If you have no backup and the stock ROM did not work, they you are pretty much out of luck. I had a backup but the IMEI didn't come back until I flashed a different modem. I used modem_XXDME4.
If you know what your IMEI number was, then there are ways to write that number directly into the phone. Need to send the phone to someone that has the hardware though. You can buy it yourself but it costs about the same as a motherboard replacement. Youtube "N7100 Android 4 3 imei repair z3x" to see what I'm talking about.
If you don't know the number, don't have a backup, then you'll have to change the motherboard.

You can find your IMEI number on the back of your phone though.. Pull out the battery, it's printed above your device's serial number.

I have my IMEI, i just wanted the solution through software can i change my IMEI or i have to go service center that would cost about Rs. 5000 minimum.
modem_XXDME4 is S3 modem, how can i flash it on note 2 N7100.
PLEASE HELP

@dineshdotcom2000 have you tried different modem? I had the same problem like yours and flashing my region's modem didn't solve the problem. I flashed European modem - modem_XXDME4 - and the dummy IMEI changed back to the original. Maybe you should give it a try.
Here is the link https://www.dropbox.com/s/5mrtz2c6s29ibxt/modem_XXDME4__.zip
I flashed the exact same file on my device and it worked. Good luck :good:

Find a service in india that has a z3x box. They can write the IMEI directly without swapping the motherboard.

just search, a few days ago there was the same problem solved probably in Q&A thread

broken IMEI

Hello guys. This is my first post and i need help
i installed original samsung note 2 n7100 rom and i cant call or get sms from anyone!
i searched on the internet and i fount my imei is broken.
its not same as in the back. i tried many method but no solution. also in my country changing imei is a big problem.
so is there anyway to fix this issue? because i dont want to pay a hundred box for it.
living with 500 box in a month and i cant pay that money.
[tried efs pro and got root error. also i got root access on my device]

Which ROM did you flash ? What's your current modem ?

Where did you get the phone?
Does the IMEI start with 0049?
