Before you start READ THE GUIDE once so you can understand it and then proceed with repair.

http://d-h.st/U08 omap4420 wkparks

and google omap flashinstaller

Step1.

Install LGflashtool (also copy/paste crack)

P920 users should run LG FlashTool and load BOOTV21E_AP.bin (ONLY THE AP.BIN FILE) and keep it open but NOT ready for flashing.

SU760 users should run LG FlashTool and load SU760V10GROM (ONLY THE AP.BIN FILE) and keep it open but NOT ready for flashing.

Step 2.

Extract WKPARKS omap4boot and follow installation steps:

Install OMAP4430 USB driver

Quote:

If you plug your Phone on PC without battery, OMAP4430 device appeared for seconds and then disappeared in your Windows Device Manager

(check arsen4oo photo guide in post #3)

On windows 7 sometimes OMAP4430 flashes too fast so you cant install driver.

There is a a windows feature that will help you install the driver easier.

To view devices that were once installed but are no longer attached to the computer, open a Command Prompt window using the Run As Administrator option and enter the command:

SET DEVMGR_SHOW_NONPRESENT_DEVICES=1

Then, from the same command prompt, type devmgmt.msc to open Device Manager. Choose View, Show Hidden Devices. The new instance of Device Manager will show “ghosted” entries for devices that were once present. This technique is especially useful for fixing problems caused by leftover drivers after replacing a network card or video card—you can easily delete the ghosted device or update the OMAP4430 driver.

After driver installation ends remove usb cable BUT keep windows device manager open.

Step 3. Run start_fastboot.bat and select option 2

Step 4. Pull out battery

Step 5. Hold Vol+

Step 6. Connect USB cable, the usbboot will start

Step 7. Insert battery while the usbboot is waiting

Step 8. Script tells you to remove cable but i dont think it's necessary in this version

Step 9. Release Vol+ and look in your Windows Device manager

If everything worked ok your phone got recognised and now you are in downoad mode.

Step 10. Change LG USB Serial Port according to LG FlashTool Guide to port 41.

Step 11. Remove cable and battery from P920/SU760

Step 12. Set LG FlashTool ready for flashing.

Step 13. Run Steps 3-9 again and you will see your phone being flashed from LG FlashTool.

It will be stopped at 26-30% because phone will turn off on its own BUT the next time you try to enter NORMAL DOWNLOAD MODE it will be available again.

Step 14. Set LG FlashTool ready to flash your P920 with BOOTV21E_AP.bin again.

SU760 users should use SU760V10GROM bin .

Step 15. Put your phone in DOWNLOAD MODE without using omap4boot this time.

Step 16. LG FlashTool will recognise the phone and flash it completely this time.

P920 after reboot will go to CWM. You can flash your personal backup or reboot to STOCK V21E.
