DEBRAND/UPDATE/DOWNGRADE:

Without any data-loss!

After the debrand/update/downgrade ready.
Attention to root again, reboot and reflash Clockworksmod 4.0.0.9 before trying recoverymod.
Otherwise it will be a factory reset.

This is what you need:

-LG B2CAppSetup: http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
-Driver LGP920: http://www.multiupload.com/820UL7SM7D

4) Pressing Vol.up + power 6-7 seconde wait for the LG logo and The screen turns off
5) Again pressing Vol.up + power 6-7 seconde and wait until the drivers are installed (LG Mobile update detects your phone and the screen is always off)
-If this is the first time the driver install redone item 5).
6) Open your Device Manager and deactivate the "LGE Mobile USB Modem" in the modem section
7) Start KDZ_FW_UPD.exe
8) Select "Type:3GQCT" "PhoneMode: CS_EMERGENCY"
9) Now select at "KDZ file" V10D_00.kdz (for update) or V10B_00.kdz (for downgrade)
10) And klick "Launch software update"
11) Let the tool run. Don't klick it, even the Window sais that it's not responding! (The Log can be ignored, especially the missing dll messages)
12a) For downgrade V10B_00.kdz Wait till your phone reboots
12b) For update V10D_00.kdz Wait This log:
14:37:21 : CDMA: wParam = 2004, lParam = 99

Thanks a lot for your work.
2 hours ago I send my phone to repair.... Oh man :(
Next time please tell me this earlier :)
But no problem - so in future all O3d users can be sure to have a good method to go back / reset the phone.
And I have no fear to put again clockworkmod etc. on my phone when its back...

Thanks and greez

Not working here mate,
Followed steps to the letter. Software update (kdz) not responding. Window still open that says
MOD UptestEX MFC Application has stopped working.

I haven't closed the window, underneath Software update log is stuck on Unpacking KDZ... that was 20 mins ago.


What do you think mate? All run as admin all drivers installed, Modem disabled etc. Should I terminate the UpTestEX window do you think?

Not sure what sort of state my phone is in at the moment behind the scenes.

What a game eh?

edit***

Terminated updater and phone rebooted O.K..... still on old fw and rooted so not touched I guess?

Will give that a bash later and report back.

Nope, restarted PC and tried again. Not going to happen. Followed everything to the last letter. I get nothing in the log after unpacking kdz (when app crashes). Like before I waited 15 mins and no action.
Don't have any XP machines to try it on so I guess I'll just wait for a different method.

Thanks for trying to help though mate.

    You think I will sstuck at update screen?
    How can i avoid that?
    I had a hero before, there was no such a problem for me.
    Can I brick it permanently?
    : ) thanks for advice

    Yes you can brick it, it's not really permanent brick but for now there is no solution for it, it happened to at least 5 guys I know and almost all send it back to LG, my replacement should arrive tomorrow.

    The thing you shouldn't do is do like me, start from V10D with clockwork mod installed and then upgrade via the LG update that will get you stuck in recovery and if you then use the LG update tool that will get you stuck in Firmware update screen and then you are screwed.
