    Beginning yesterday morning I had no working connection with my phone (no cell coverage, no data, wifi wouldn't connect) and this came after 4-5 days of signal dropping in and out sporatically. I tried a few fixes (airport mode, factory reset in CWD recovery) but nothing has worked. I'm now trying to unroot my phone to do a factory reset with the stock firmware.

    I was following the instructions here http://forums.androidcentral.com/lg-...using-kdz.html

    I am able to install msxml fine. I install the LG drivers on the PC I'm using and run the KDZ installer using 3GQCT as the type, DIAG as the PhoneMode and the kdz5 file. When I click launch software update, I see the log saying Launching SW update then Unpacking KDZ, but then the program freezes. There is no change on my plugged in phone (in recovery mode.) The only change I can see is a filing cabinet icon appears for a minute or so on the desktop and then disappears. I have tried running the updater on two different computers and waiting between 5 and 30 minutes, but I've had no luck.

    Is there something I'm doing wrong?

    Please read carefully.,make sure you understand each step before attempting this, if you don't understand something, ask questions.

    What baseband is your phone? If it's a ZV4 baseband you would be better using the KP500 utility. I just unbricked my ZV4 using it. I still have an unlocked bootloader (You won't after the ZV9 update).
    If you need help and the VM670ZV4.cab, let me know. I just wrote a text document that spells everything out Including how to fix some common and not to common problems.
