I didn't create this tool, I just found out a way to make it works with our phone, and maybe I'm not the first (tested under Windows 7 Ultimate 32-bit).

What do you need:

  • omap4boot, get it from original thread.
  1. Extract omap4boot archive somewhere like C:\omap4boot (I will use this path in the tutorial).
  2. Power off your phone and remove the battery.
  3. Connect your phone (still without the battery) to the PC.
  4. You will hear the sound of a new driver, then the sound of a driver when it disconnects continiusly.
  5. Start -> Right click on "Computer" -> "Manage".
  6. On the left column, click on "Device manager".
  7. You will see a device that appear and disappear under "Other/Unknown Devices".
  8. You must right click on the unknown device before it disappear, once clicked select "Driver Update". (You can use this tip to make the process easier http://forum.xda-developers.com/show...php?p=51019004).
  9. Click on the second button (manually install driver) and insert the "usb_drv_windows" path (C:\omap4boot\usb_drv_windows) and install the driver.
  10. Disconnect the phone from the PC and power it off.
  11. Open a command prompt (Win+R, type cmd and press Enter).
  12. Type the following command in the command prompt:
    Code:
    cd C:\omap4boot
    start-fastboot.bat
  13. Now input 3 (Prada 3.0 P940) and press enter.
  14. Plug the phone without battery to the PC, when the tool says "Wait 5 seconds" put the battery in your phone.
    (The first time that you do this, you have to install the drivers again. Repeat step 9)
  15. At the other prompts answer always "N", this could be important.

Now you can use fastboot on L9 Next times you can start from step 12.

(the red rettangle isn't important here )

Sorry for my english, if someone wants to review the tutorial just send me a PM.

please someone explain step number 13, i dont understand

Omap4boot is not necessary. In fact you can do everything with the LG drivers, as long as u use stock rom. And probably no Windows newer than Seven, as Win8.1 has some general usb related problems. With a custom rom u need the usb drivers from the Google SDK for Fastboot and Adb, and the Lg drivers for Download mode and tethering, as they provide virtual com ports and modem, while no longer recognizing the phone in all other situations. Same goes for all LG software.

When issuing a command line command without specifying a full path to the file to execute make sure you change directories to the folder where the script/executable you want to run is located.

Your error message is because the system can't find the script in question with in the environments path. This applies to Linux as well as Windows.

There's an old tool fore the L9 here, somewhere, with a graphical Interface, which can unlock the bootloader and install several recoveries, if it's that what u want. For mire spohisticated operations, learn the DOS AND the UNIX/Linux. Oldskool stuff, with manually entering paths, employing environment variables and such. Mi no gustet, too.

I wouldn't even get to this point with the phone in Fastboot mode. Now you can manually assign drivers for good. Up to Win8.1 from the two categories "ADB interfaces" and "Android phone", but in Win10 seemingly only one of them has survived, containing fewer drivers. Drivers which appear in the other category in older Windows seem unavailable, even if you just installed them.
