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:

-The kdz: V10D_00.kdz or V10B_00.kdz (for downgrade) http://forum.xda-developers.com/show....php?t=1155874
-KDZ_FW_UPD_EN: http://forum.xda-developers.com/show...05&postcount=1
-LG B2CAppSetup: http://csmg.lgmobile.com:9002/client...2CAppSetup.exe
-Driver LGP920: http://www.multiupload.com/820UL7SM7D
-Your LG P920

Only for windows xp 32bit SP3.

I) Install B2CAppSetup.exe
II) Install LGUnitedMobileDriver_S4981MAN32AP22_ML_WHQL_Ver_3. 2.1.exe
III) Unpack the KDZ_FW_UPD_EN.7z and install the msxml.msi

1) Start LG Mobile update
2) Power off your phone without USB cable
3) Connect the USB cable and wait for the LG logo and the annimation battery
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
14:37:21 : Model Dll Msg Not Found(2004, 99)
14:37:23 : CDMA: wParam = 2004, lParam = 100
14:37:23 : Model Dll Msg Not Found(2004, 100)
14:37:23 : CDMA: wParam = 2001, lParam = 0
14:37:23 : Model Dll Msg Not Found(2001, 0)

-Wait until your HDD activity stops
-Exit KDZ_FW_UPD
-Disconnects USB cable
-Power on your phone.

Check your version in "setting""About phone"
ENJOY!

STUCK AT LG LOGO:

with factory reset!

1) Start LG Mobile update
2) Power off your phone without USB cable
3) Connect the USB cable and wait for the LG logo and the annimation battery
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 the item 5).
6) Click on User/Support then emergency mode, insert your IMEI and click on check
7) Wait for download and upgrading (15/20 min)

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?
