[T-Mobile LG G2x] eatabagel:
I have the same problem. I was in the middle of an upgrade using the KDZ updater when something went awry and the updater said something like "There was a problem with the connection with the phone".

I was then stuck on the S/W Update screen for a while until I tried the scrubber/nullifier in this thread: http://xdaforums.com/showthread.php?t=1590523

I was then able to flash CM7, and other ROMs but didn't have my APN, and was unable to recover it using various methods. No network, no battery status. I believe my radio must've been partially flashed and corrupted in the process of udpating the ROM. So does anybody have any tips?

Currently, I've been trying to restart the KDZ updater process again and again. It seems to be working fine at first (both for 3GQCT and CDMA, and Emergency or DIAG modes) but I get all the way to:

12:32:50: CDMA: wParam = 2010. IParam = 3036

12:32:50: Model Dll Msg Not Found(2010, 3036)

And it just gets stuck there. I don't get anymore Model Dll Msg spam, etc.

I am losing hope.

Here's some more info on where I'm at.

It seems I get different results for when I either do CDMA or 3GQCT. If I do CDMA/DIAG I get all the way to what I posted above.

If I do 3GQCT/EMERGENCY The Phone Update window reports:

Problem with communication between cell phone and PC

Please disconnect the cable from your cell phone in order and remove and connect the battery.

Power on your cell phone and press the Restart button to resume update.

I think something in there got corrupted and is preventing APN from loading or battery information to show, and is also preventing the software updater from finding what it needs to update. I don't know... sad.
