[Q] Lost IMEI after upgrade

NoKeR · Apr 18, 2011

Hi all!

I were in the process to upgrade to 10b on my phone, but during the upgrade the phone stopped responding on upgrading S/W. Please wait. And after some time on that screen, I removed the battery and cable, and tried the different solutions provided by the LG B2C Support Tool.

After that I tried to flash the phone with smartflash and the latest software. And that worked perfectly, but now the phone has no IMEI. Have tried to install the backup I had via CWM but still no IMEI.

I was looking forward to use the 2x this easter, but if noone has a good solution in getting the IMEI back, the phone needs to go on a easter holiday to the service centre.

You did the same thing with me. When using smartflash, DO NOT check option "Erase CAL data" but I did. My SU660 now has serial number = 0000000. P990 will lost IMEI.

I had the same problem, you need to flash the baseband firmware as it is gone.
I think that it was during updating the baseband as part of the V10b mine stopped flashing.
Look here: http://xdaforums.com/showthread.php?t=1008070

It worked with mine o2x.

I managed to solve the situation.

I applied the 10b firmware using nvflash. And then flashed the 10a fw with smartflash, checked that the IMEI were back in business. And then did a new update using smartflash to 10b and now everything is back as normal

restore IMEI (From Modaco)

1. Connect phone by USB
2. Enter 1809#*990# in dialer
3. Select Port Settings -> Select CP USB
4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200
5. Type AT if response is not OK, change port number
6. Type at%imei, it should display your current IMEI
7. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x , where x,x,x... is your orginal IMEI number
8. Reset

Hi mohicanrat,
I tried to set 'Port Setting' -> 'CP USB', but in the device manager (i'm using win7), this device then shows up as 'Other Devices' -> 'Unknown device'.

What should I do now? Where can I get the device driver for this?

hello,

please where i go to "Start hyperterminal, in COM settings"

Rusty! · Jul 19, 2011

HyperTerminal was binned after Windows XP, if you have Vista onwards you'll need to download an equivalent.

It gives error on running at%imei, might it be because phone driver not installed on windows?
at%imei
ERROR

I instaled driver from LG site LGUnitedMobileDriver_S498MA22_WHQL_ML_Ver_2.2.exe
when i type ATI4 for instance it shows same info as from log.

Here's log from modem i removed my IMEI though.

Today i was flashing LG Optimus Black P970 with SmartFlash and accidentaly i checked "Erase entire CP". In a result my IMEI has changed...

With this tutorial I managed to recover my IMEI successfully!
It took me 2 minutes and worked at first time.

llcoolr · Feb 21, 2012

i'm trying this method but not working

when type At...i get ok
but when i type imei i get error

radkor · Feb 21, 2012

What error? Paste screenshot or log.
What firmware version do you have in your LG?
You must type exactly this: at%imei - (% symbol is very important) it will display your current IMEI, then
at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x (, (comma) is very important too)

Kubanac · Feb 24, 2012

Stock ROM V10c

Tried to downgrade baseband from

Can you please tell me exact software version on what this method worked?

vision2040 · Mar 23, 2012

Anyone know how to perform this with an Optimus L3 device? Apparently i can't have acces to "Port Settings"
