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?

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..

HELP!! Lost IMEI number!!!

Lost the imei tinkering.. Have no clue how but it is now missing from the settings and will not connect to the network. This is on my tmo g3. Please help

Dial *#06#

Nothing

What have you done to the phone?

Most of the time there is a sticker under the battery.

Yeah but what do i use to get the imei back inside the phone instead of just the sticker

Will donate if somebody can help me figure this out..

Isn't this that efs backup stuff talked about in the PurpleDrake thread?

As Skizzy034 noted you'll need to have performed an EFS backup. You can either flash the zips you made or use ADB to restore the partition.

Or call t mobile and tell em your phone does not work right and get replacement. You still never said what happened? What did you do right before issue happened?

I believe I saw a efs recovery method in the lg g2 forum but it looked like a long process and it might not even work for our phone. If I was you I would try to find it quick because normally anything that can potentially spoof imei numbers gets deleted when a moderator notices it.

That's of no help unless somebody comes out with a method for restoring without a backup (I've seen it done with a couple devices). Until that happens, unfortunately there's not a lot you can do with the device.

Do a search for a member by the name Odia, I messed mine up before on another phone and He helped me restore withbout any backup. This was before I ever heard of efs

What about if your phone has the WRONG imei number after flashing a ROM? Does that matter? The phone still works.

I don't have any info on being able to help but this is a prime example of why you take the few extra steps and back up. Most of the time I'll admit, in fact I have never needed mine but on those rare occasions its literally a phone saver.

Same happened to me! Did you fixed it or send it back for repair?

Editing the IMEI in any way is illegal and against our rules. The only allowed way is to have a backup. Anything else is not allowed here.
Also do not Suggest people send the device in to be repaired under warranty. This is Fraud and also not allowed.

Anyone willing to share their EFS backup?

Apparently my old s4 is now reading unknown for baseband and null null when trying to view the imei. If it isn't to much to ask would someone be willing to share their s4 efs backup? Please pm if possible. Thanks again.

No one is willing to share their EFS backup with you. That's like someone giving you their phone.

yes i can, but how can i give it to you?

You will be unable to use it with your phone anyways. Efs is made specifically for your phone and your phone alone. It contains data that interacts with hardware on your phone and will be incompatible using any other efs configuration. What do you need an efs for?

IMEI lost, questions about backing up another MOTO Z Play "EFS".

Hi, I've been trying to find a solution for the problem of null IMEI I'm having after wiping EFS partition on the Chinese TWRP, maybe it's not that and it is because I've erased modemst1, modemst2 and flashed modem+fsg.
I'm pretty sure it had to do with one of those procedures, when I wiped the EFS I've got some error saying it couldn't be done but something went missing.
I've got a more direct question now, my brother just bought a Moto Z Play yesterday, if I backup his EFS on my phone (he already asked if I want to do that) will both of us would be able to use our phone normally?

can anyone backup their "efs" and upload it here so that i can restore it and get back my imei.
plzzz. needed indian efs

No way, like you already now, each phone has an individual IMEI. Your phone is unfortunately unusable.
What did you attempt to do? Flash another firmware package ?

Lenovo could generate it. But they probably instead replace the main board. You may ask them how much the repair is.

I think I'll just take it there and see if they can do anything about.
well, lesson learnt hard way

Now you know not to use fishy Chinese recoveries.

Hey you can use sigma box to restore imei which will cost you around 800 rs,same thing happened for me but still not fixed just using with wifi

If partition can be wiped, then is not read only. If is not read only, should be possible to write backup back. Otherwise, what's the point of the backup?!
Each phone should/must have different IMEI, depending of the network. In theory, should be possible to take partition from one phone and write to another. However, Moto maybe prevents that checking some hash, serial number... If it's possible to write partition from another phone, again question is can those two phones be on the same network in the same time. I also saw a way to change IMEI, I think even on this sub forum.

If someone solve this problem I definitive pay to that sir, he would be rich In the first day..

did u got efs, im too wiped my efs partition

IMEI away

Hello I had Protax installed everything ran perfectly. But I installed the stockrom again. But then my IMEI was 0. I installed LineageOS and my IMEI was still 0. So I installed Xposed with an IMEI changer and changed my IMEI. And when I * # 06 # calls is also my right IMEI there. But in the settings my IMEI is 0. I can not make any calls or log in to the network. What can I do?

I think you cant do anything without efs partition backup

hi !
have you tried to flash a firmware with odin ? but with "re-partition" for a full restoration...
Or by a PC ,with smart swift or kies you have a process of restoration after a fail and errors...

i had that issue with my old s2 and a technique in a store got it fixed i gave him the box and he did it
