[Q] Invalid imei / corrupted efs file.

Hello, I need serious help :/
After flashing Paranoid 3.6 into my device, I lost mobile network. So I came back to stock 4.1.2.
I wasn't backup efs file before flashing. As you can see, it displays wrong imei/serial number and etc.
I can not find EFS backup in my device using this method - http://forum.xda-developers.com/showthread.php?t=2356658

Did you search your entire device for the folder efs_Backup? It should create automatically. If you don't find that. Use note2 toolkit and restock.

Hi.. Exactly the same as my problem.. Even changed imei is the same.. Which recovery do you use? I use twrp recovery and it backup efs. I just restore imei with twrp and everything went fine..

Exactly the same issue, my imei number went to same as yours ending with 0000. I don't have efs backup and i am a newbie too. but still i have tried restocking the rom using ODIN but didn't help. any help on this will be much appreciated. I can't access network due to serial number is corrupted.

number 1 rule, to do backup before flashing anything.
there is sticky guide in general.
flash new modem and bootloader, it should fix it

I have a phone backup not the EFS backup. The Imei got corrupted all of a sudden. Next time i'll keep a EFS backup. i have few stock roms but i don't have Modem / recovery Roms and i found this thread " http://forum.xda-developers.com/showpost.php?p=31986738&postcount=6 " but the links are dead. You got any links to download stock ROMS along with Modem / Recovery / Bootloader , then please do share. Also, ROM links are slow if you can provide fast meta link that would help.

(Resolved!) Disaster ... No Signal after installing different ROM

My phone is LG Optimus G Pro F240K
I installed E988 (United Arab Emirates) then after that I got a message that my storage is encrypted and I have to supply a password to decrypt it, which I managed to solve by "Hard Reset". The Decrypted storage is solved but my IMEI disappeared and No signal!
I flashed back to my original ROM, F240K10r_00.kdz , using the XQ55 method.
after flashing original ROM, still no signal
Now I am very very upset and in need for urgent help sense there is absolutely no enough resources on the internet.

Hi! The same situation was with the LG Optimus G Pro F240L - after flashing from F240K.
corrected as follows:
1. flash the firmware from LGE980H (TCL / TELCEL (MEXICO))
2. flash the firmware of your phone. radio is turned on

You rolled the dice by flashing a rom For a different model. Not so sure that was a wise move.

Why would you do something like this when theres not even a base to flash ... I'm mean really

Guys he needs some help not reproaches

Unfortunately there's nothing that can be done unless he has a backup that he can restore. Once you loose the imei it's more than likely gone for good. I lost mine on the e980 twice. First time a backup restoration fixed it. Second time I had to swap the phone. And as for the app for restoring imei, I tested it but it doesn't work with our phones at all.
Edit: you try reinstalling the baseband. As for how you would get it, I know have no clue.

He hasn't reported if they work for him so I'm assuming they don't work on our phones.

When did the problem start exactly. My guess is that its an efs structure problem. Done by updating to a newer samsumg rom TW etc..
Also, are your imei and serial intact Nazgul?

Read up on that before you install it. It may not be exactly what you are looking for. Just a heads up.
Its usually used for no imei and serial. Not the same issue you are having. But as I said, read up on it

Its used for patching your existing imei and restoring not only for no imei

You have downgraded yr bootloader...
Check yr knox status it might be showing 0×1
If thats the case simply flash twrp custom recovery n root yr device using dr.ketans utility tool.
N try taking efs back (all though its late)
Then download DN3 V4 RC2 custom rom from dev section and flash it.
Might get life back to yr note2...
Or
If yr knox status is 0×0
Try flashing stock 4.4.2 rom available for india.
This might bring back yr imei no..n phone to working state

Hi download and flash this http://www.mediafire.com/?9li221fj96r66qb hope it helps
