[Q] Downgrade LG P500 to Telus 2.2

I tried to downgrade LG P500 from 2.2.1 to 2.2 by following these steps.
Install msxml.msi from the uncompressed directory
Conect your device (do not turn on disk storage) and run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT
Select PhoneMode : DIAG
In KDZ file : Choose the ROM file you downloaded (V10G_00.kdz file)
Press Launch software update and wait (It will be 10 minutes or so). In your phone it will appear "Emergency mode". Wait until it reboots.
The phone never rebooted. When I manually try to reboot, it comes to Android screen and never gets past it. Has anyone faced this issue?
Thanks.

FIRST TRY TO PRESS THE POWER BUTTON FR FEW SECONDS WHEN ITS SHOWING THE ANDROID SCREEN IF IT LOAD STHEN ITS FINE ORELSE TRY THIS
IT does happen so in order to get it working make sure that u have enable usb debugginng and disable lg modem driver .
Restart ur pc

flash using kdz flasher choosing your rom file in diag/emergency/cs emergency(any 1)option
after it succeed flashing it will show battery getting charged but it never turns on on its own so manualy turn on the mobile.
Note : Do not disconnect usb from pc till the android loads up in ur mobile
if all doent work just gv it back to service they will get it repaired

thanks for reply. i work sucessfully. let me share my experience with you.
No exact steps, just some points:
1) Use XP.
2) uninstall all old LG drivers.
3) install OMap & 2 LG drivers.
4) the phone come with battery (if no battery, my pc don't find my phone). Volume up + connect USB.
- Omap didn't appear (i don't know whether the reason is my phone installed OMAP beflore or not).
- Only LG 2-3 drivers to be installed.
5) execute LG flash tool, steps 12-17. Disconnects usb, battery off & in, volume up+connectUSB
6) The update process will begin automatically after that release the “vol up”.
7) phone reboot at 80% (showing "AP download SUccess"), counting continue. (whole procedure finish).
8) few mins later, target is resetting --> reset--..... (showing "Download Fail!)
thnaks grean again.

i have 2 Prada 3.0, the one normal can be flashed vai this way. the another is suck at "S/W screen when i turn it on. but can't be flased via this way, just keep "download fail" after 1-2mins updateing.

[GUIDE] [TOOL] Rooting the official ICS ROM

I've tried many different ways and many have failed me, so I'm documenting one way which worked for me.
You will need the Acura recovery
http://www.mediafire.com/?5io5b2r98nt28bb
and gazhead's SU zip
http://forum.xda-developers.com/attachment.php?attachmentid=1352095&d=1348524309
Preparation
Extract the recovery package
Step 1: Drivers
Make sure you have the OMAP 4430 drivers installed.
If you do, skip this step
Note: On windows 8, you will need to have rebooted your computer into a mode which lets you install unsigned drivers. Do a Google search to find out how.
To install the omap drivers:
Turn off the phone
Remove the battery
Open Windows' device manager
Connect the phone to the PC.
When OMAP4430 appears in your list of devices, double-click on it and select "update driver software"
When asked, pick the usb_drv_windows folder extracted from the recovery package and go through with the installation
When the installation has completed, you should have a new category called "Ti Boards" with the OMAP4430 USB device under it.
Step 2: Installing recovery
Disconnect the phone
Go to the recovery folder and launch "Instalar Recovery ICS Europeo.bat"
The script will be waiting for the phone to be connected.
Press "vol up"
Connect your phone, without any battery
As soon as the script does something, release the button and insert the battery
As soon as the script stops, disconnect the USB cable.
When you see the silver LG logo, connect the USB cable again
The script should complete its task soon after that.
Note: If the script is waiting for something, pay attention to your list of devices, you may have a LG COSMO device which has no drivers. If this is the case, install the OMAP4430 drivers and start the script again.
Step 3: Rooting
Put gazhead's file on your SD card
Turn off phone
Press "vol down" + 3D button + power to boot into recovery
Install the zip file from your SD card
Reboot
That's it. Help me improve this post by reporting any errors you see and I hope this will save people some time

Are you sure that you pressed:
"vol down" + 3D button + power
?
It seems the combination changes depending on the recovery...

Try releasing the vol key before inserting the battery. This worked for me.

fastboot failed to load , try again until you get the fastboot menu , try to press vol- instead of vol+ or even no vol button at all

I cant enter recovery mode
i just installed and then pressed the buttons but it doesnt work
Edit: I rooted by installing TWRP recovery and it worked

Lets say i TOTALLY screw this up.. what is the absolute worst case scenario? Can i brick it or is soft brick worst case?

It can be fixed

Space for Apps
Good evening, the home version of SU760 had 2GB of space for installing applications ... Already the European version of the P920, only has 1GB of internal memory dedicated space .... Is there a way to change this? Well I tried to restore the apps that I had, and gave memory overflow ...
Thanks

Is there any chance of "security error" with this?
