[P920/5] [SU760] Resurrection Guide (Lets get those brick's fixed...)
[I]This guide will repair most of P920/SU760 devices that have been flashed with wrong ROM packages and cannot enter DOWNLOAD MODE anymore.
If something doesn't work for you make a post describing exactly what you did , your phone model and your operating system.
Before making pointless posts READ THE GUIDE.
If you don't know how to make one of the recovery programs work READ THEIR GUIDE .
You can find links in the end of this post.
This guide requires that you have installed correct LG DRIVERS and you have a working NORMAL LG USB CABLE also you need to do this with a good battery.
Before you start READ THE GUIDE once so you can understand it and then proceed with repair.
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.
Extract WKPARKS omap4boot and follow installation steps:
Install OMAP4430 USB driver
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.
Step 17. After repairing your P920/SU760 YOU PROBABLY HAVE TO FIX YOUR IMEI...(and maybe your wifi mac address) follow these steps:

4.Select Port Settings -> Select CP Image Download
5.A new device should appear at let it install
6.Open Tutty (or hyperterminal) and select serial protocol. Click on open
7.Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
8.Type at%imei, it should display a dummy IMEI
9.Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x where x,x,x... is your orginal IMEI number (found under the battery of your phone). It should response IMEI WRITE OK
If you don't understand how to do this read this thread [GUIDE] Unlock Phone / Recover IMEI
Extra Step for P920 User's
After procedure ends use the rebooter utility and select option 2 like below..
If you get this screen on P920/SU760 you are in FASTBOOT MODE.
If you get messages like this you probably have a BAD CABLE.

A Small Guide if Anyone has troubles installing Omap4430 Driver in Windows 7 When plugging the phone in,find OMAP4430 in "Other Devices" in Device Manager.
Right click on OMAP4430,then click "Update Driver Software..."
Then browse to your omap4boot 1.8 folder that you have extracted from zip
Choose the usb_drv_windows folder and click OK
While installing the driver,ignore any warning messages
After installation finished you will be able to ressurect your phone

I have Bricked My LG SU 760, I have tried every thing to get it back but no success...
I can Flash it with smart flash tool but after flashing completes, phone does not turn on.
I can go into fastboot mode with omap4 bootloader but while trying to flash a file, I always get the message REMOTE PARTITION DOES NOT EXIST.
