Hyperterminal.
[LG Optimus 3D] LeighR:
I am having this exact same problem. I'm using XBSA's ICS. In PORT SETTING in the Hidden Menu, I don't have the option to select "CP Image Download". Instead, I have CP USB, CP RESET and CP UART, plus a few other non CP options. I tried them all anyway.

I also cannot change the port, which seems irrelevant anyway as the new device won't install properly when I select the options in PORT SETTING.

Any ideas guys? I'm scouring the forums looking for a way to restore my IMEI. Its right there under my battery but I can't correct it and so I can't use my phone. Thanks in advance

CP USB
[LG Optimus 3D] LeighR:
Thanks
[LG Optimus 3D] LeighR:
I've been trying everything and I still can't get the "AT%IMEI" command to work. I wonder if its a driver problem, although I've tried installing all sorts. Someone please help :(

Edit - got it fixed. I used the info provided by XBSA and had a play around as well. If you are on ICS404, the guide is a little different

1. Set phone to Settings > Connectivity > USB connection type > LG Software. Connect phone to PC by USB and let the drivers install. No need to download LG PC Suite

2. Activate USB debug mode

3. Enter 3845#*760# in dialer

4. Select Port Settings -> Select CP USB

5. A new device should appear. Let it install

6. Open Tutty and select serial protocol. Click on open

7. Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)

8. Type at%imei, it should display a dummy IMEI

9. 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 (found under the battery of your phone).

It should response IMEI WRITE OK

10. Reboot phone

Like most of these guides, so simple once you've done it but horrific when you can't figure it out. Such small details can make a huge difference if you're a bit n00bish

Also thanks to Pesach85 for being cool and responding to my PM so quickly

Where is cp image my fhone?

It's maybe work on LG Nexus 4?
[LG Optimus 3D] Pesach85:
Ok, i understand you are living a sort of panic, but relax.

So yes after Cp you have to do ok...let install the peripheric, it's automatic so don't care how is it called.

In tutty yes select the lge modem port.

Keep present that if you are able TO receive the reply after AT command is a good signal.

The issue may be in the USB cable too if it disconnect soon.

Do different attempts and let us know.

Ok, when I select CP download mode and press OK:

1) My PC recognizes a connected device, but after one second it disconnects itself.

2) when I return in Port settings, CP USB is selected instead of CP download mode. Is it normal?

Here you are a screenshot of what exactly happens to me.

May it be a wrong tutty configuration problem? I changed my usb cable but same result!

Could it be a driver issue? can someone give me the exact drivers needed for this operation?

EDIT: I just completely uninstalled all the LG related drivers, and re-installed their lastest version after a reboot.

When I connect the phone and select CP download mode it displays me a new device, but doesn't let me install it.

[LG Optimus 3D] Delux9364:
yeah, I just did it, but it simply shows me the dummy imei (yes, that's what happens if I copy-paste at%imei=m,y,o,w,n,i,m,e,i)

[LG Optimus 3D] Delux9364:
Ok guys, I've not solved my problem yet, but I had a short conversation with Pesach85 and noticed a very strange thing:

When I connect the phone in debug mode, my PC recognizes some new hardware, such as the LGE android platform USB modem and other devices.

If I enable cp image download, a new hardware is installed (Intel(R) Flash Loader utility ), but the previous hardware (that means the LGE android platform USB modem) disconnects itself.

If someone tells me how to keep all the hardware connected, I would be able to repair my imei.

Please rescue me!
[LG Optimus 3D] LeighR:
When the new device is detected after you select CP, did you let it install?

OOOOOOOK guys I finally fixed my problem! http://xdaforums.com/showthread.php?t=2052979

@mesherbrum that's because you aren't in cp image download mode.

If, when you are connected in cp download mode, you cannot interact with tutty (make sure Intel(R) USB Flash Loader appears in Universal Serial Bus controller from device manager), then you've my same problem.

Heey guys!

Just wanted to check if this is the message you guys get when your IMEI is messed up:
[LG Optimus 3D] LeighR:
No, I had no warning except a suspicion. I posted my IMEI and XBSA said it was corrupt. So I fixed it and my network signal came back
[LG Optimus 3D] omgomg:
But this is what shows up when you type *#06# on the dial pad.
[LG Optimus 3D] xbsall:
There 2 things that can happen with LG phones..

One is to have corrupted baseband with no IMEI and the second is to have the generic IMEI that ends with 00001 which is banned from some providers.

In both cases the original IMEI should be restored.

[LG Optimus 3D] iodak:
You cant write IMEI if original one is still there. You must somehow delete it. Flash p940 cp or use option erase entire cp in smartflash tool. Then you will have some generic IMEI ( 350305260000001). Then you will be able to write original, and your phone will be ok.

Losing IMEI

Every time I try and flash First ICS 4.0.4 Full 3D ROM Ported From SU760 I lose IMEI.

The only thing i'm doing differently than the tutorial is im using SmartFlash instead of FlashTool.

I cant get OMAP to stick, it pops up and then disappears.

I also cant get FlashUSB device to stick either.

I have been flashing Stock GB with SmartFlash, and then running Phone Recovery in LG Mobile Support Tool to get my IMEI back.

But then i'm back where i started.

Hey all,

When I get to the step where I have to enter CP Image Download mode, the drivers don't install. In the original post, it doesn't mention anything about installing drivers for that particular step, so I assumed it installs automatically? Each time I try to install the driver (by plugging phone into computer in CP image download) it takes about 5~ minutes and the installation of drivers fail.

Any thoughts?

Problem with recovering IMEI using Tutty/Putty/Hyperterminal

Hi there!

I bricked my p920 a week ago while trying to flash the ported 3D-ICS rom from xbsall. I don't really know what I did wrong, but somehow I destroyed my bootloader.

However, using the "p920 resurrection guide" (http://xdaforums.com/showthread.php?t=1942836), I was able to boot my phone again and to restore my nandroid backup, so that I'm back to stock-GB now.

Everything works fine, except that my phone does not find any network and has no IMEI anymore (yes, I know, these two symptoms are connected ;))

I tried to recover my IMEI using this guide here, but I always get stuck at point 9 of the instructions (trying to type in the original IMEI using Tutty).

So far, everything goes according to the guide. I connected Tutty with my phone using COM-port 3 (the only port available in Tutty) and when I type "AT" in Tutty, the expected "OK" comes as a response.

But when I try to type "at%imei", the only response I get is "ERROR".

By accident I also typed "at imei" one time, the response I got was "56000 56000 OK".

...later today I'll add a screenshot with my latest Tutty-session...

So, what am I doing wrong? So far I only tried all that with a Win7(64bit) PC. All drivers for my phone, Omap and Infineon are installed.

I also tried to use Putty and Hyperterminal instead of Tutty, but with the exact same results.

Any ideas?

Imei write error issue [solved]

Listen everyone who has following error:

I had the same when I tried to write my ORIGINAL IMEI. I tried almost everything what's written here, But everytime had "IMEI WRITE ERROR"

The reason was my original IMEI was incorrect, it had checksum error. I knew that when I checked my imei. Then I changed one digit and it was correct and was free. And finally I managed to change my imei!

Search google for "imei check"

Hope it helps!!!
[LG Optimus 3D] Jhodad:
Hello, thanks for the Tut, however I'm, having a problem, as soon as I click OK on the CP Image port option, it doesn't save and then Tutty will always give me a COM error, I'm running on Windows 8 and I'm guessing it's what's causing problems, perhaps not, what should I do?
[LG Optimus 3D] Jhodad:
OK NEVERMIND LOL, I was using a USB 3.0 and it gave me small problems

and also if you get an error you MUST type the commands REALLY fast,

AT is easy

Type at%imei it's easy too

but the last one, with your full Imei, you can just write it on a notepad, copy and on the Tutty terminal, RIGHT CLICK and it will Paste it automatically, just press enter, now it's working.
