Q. Why the imei is lost in jellybean, but not with Ginger or ICS.
A. i don't know but this sould help you with the problem
To fix the problem, you just have to follow this few steps to make it work
1. STOCK ROM, it can be Froyo, Gingerbread, or ICS, here is a rom you can use (it will work) DJANGO ICS STOCK ROM
2. Hyperterminal Descargar
3. AIOTKV5 Descargar
4. We need a baseband Ir al post (TIP: at
Venezuela, Movistar, i used version V30B)
We need to know our original imei, it's placed at the box, or in the phone, under the battery.
Ok, let's begin!
Firs Step. (Installing the Stock ROM, if you already are on Stock, go to step 2.)
We have to flash a Stock rom, in order to view flash the baseband and connect to Hyperterminal.
Assuming you are on the oldbl, we copy the IntSD-Mount-Fix.zip and our Stock ROM to SD ext, now we open the AIOTKV5 and press option 4, and follow the steps to flash the new unlocked bootloader and install a recovery.
Restart the phone and it will open the recovery, then flash the Stock ROM, in the aroma installer, install whatever you want, we just need the rom for flash a BB.
Step 2. Flashing BB
Now we have a Stock ROM, call *#06#and we will see our imei.
Open the AIOTKV5 and press option 7 and option B, follow the instructions to put your phone Download MODE
In the SmartFlash window we click on the ROM/Copy DLoption and, inCP bin we find the BB that we got from tonyp's thread we have to mark the checkbox ERASE CAL DATA. (BE SURE THE COM PORT HAS BEEN AUTOMATICALLY FILLED)
Now, we go to START, if an error show's at the end of the flash, just close that window, and click start again, do it until, it says disconnecting from phone, or something like that.
Now, we verify our actual imei *#06# and we will se that our imei has changed to something like this 38560000001 or some strange number, or no nomber.
Now call if youare on GB: 1809#*990# / if you are on ICS: 3845#*990#
It will show up a (Hidden Menu)
Click on port settings
Click on CP USB
Click OK (DO NOT MARK THE CHECKBOX)
Now we have to search the port, Equipo -> Administrar -> Port -> LG mobile USB serial Port (COM X) where the X is a number, (Remember that number)
Step 3. Installing the Hyperterminal
Intall it normally, like always.
Open the Hyperterminal, and click Cancel to any windows that shows (some windows requiere a confirmation to close a window)
Now in the main window (a white one), click anywhere, and click on "SPACEBAR KEY" and a new window will show up, to create a new connection, select there the port you just stored, (DO NOT SELECT THE LG..)
Click properties and select the right options like these:
1st checkbox: 115200
2nd checkbox: 8
3rd checkbox: Blank
4th checkbox: 1
5th checkbox: Blank
If everything's fine, the main windows will show up a, Connected: 00:00:00, in the left bottom corner.
Now type "AT" without the quotes, and press enter,
You will see this.
GREAT Now it's easy!
type " at%imei " without the quotes.
You will se a number like this: 38560000001 or other number.
Now type " at%imei=YourIMEI " without quotes, where "YourImei" is your imei, you stored at the begining.
Ejemplo: " at%imei=30265978462 "
And you are done, call *#06# and you can se your imei.
Now you just have to flash your ROM, like CyanogenMOD 10.1, PAC-man, Paranoid, etc...
