This has been tested and confirmed to be working. Follow instructions to the key and you should be good to go!

If you are having ANY issues, watch the video below before posting! It seems to solve a lot of the errors

*WARNING* *WARNING* *WARNING*

NVFlash is a powerful utility that works at a very low level on your phone. There are few safety mechanisms built into a tool like this because it is intended for use by people with suitable training. This CAN brick your device. It is unlikely to create an irrecoverable situation, but it does have the power to create a situation that you can not recover from yourself, thus requiring factory maintenance. Warranty coverage for your phone is not guaranteed after using NVFlash. Please proceed with the use of the tool carefully and at your own risk.​

Useful hint: Copy and paste the commands into the command prompt to reduce error :)

The files you need:

NVFlash.zip (Windows NVFlash app + CWM Recovery 5.0.2.0 Image)

APX Driver.zip (APX Driver)

><><><><><><><><><><><><><><><><><><><><

Optional files:

part5.img (Stock Recovery Image)

p999-4.0.0.2-external-recovery.img (CWM 4.0.0.2 Recovery Image)

p999-ext4-08222011-external-recovery.img (CWM 4.0.1.5 Recovery Image)

recovery-clockwork-5.0.1.6-p999.img (CWM 5.0.1.6 Recovery Image)

recovery-clockwork-5.0.2.0-p999.img (CWM 5.0.2.0 Recovery Image)

recovery-clockwork-5.0.2.6-p999.img (CWM 5.0.2.6 Recovery Image)

recovery-clockwork-5.0.2.7-p999.img (CWM 5.0.2.7 Recovery Image)

><><><><><><><><><><><><><><><><><><><><

Now let's extract the files:

We will be extracting to these two folders:

C:\G2x\APX Driver
C:\G2x\NVFlash

Extract APX Driver.zip to C:\G2x\APX Driver

Extract NVFlash.zip to C:\G2x\NVFlash

><><><><><><><><><><><><><><><><><><><><

Here's how to do it:

Remove the battery

Hold Vol Up/Down (and keep them held)

Insert the USB cable

Install APX driver from the your APX folder

For windows 7(and vista? please confirm):

Open Device Manager in Windows and you should see "APX Device" listed with an error

Right click on the APX device

Select 'Update driver software'

Select 'Browse my computer...'

Select 'Let me pick...'

Select 'Have disk'

Browse to directory you extracted the *driver* software to: C:\G2x\APX Driver

Select the *entire* 'APX Driver' folder; Do not go inside of it!

Accept any warnings, including the big red alert (you may need to disable UAC)

Now in Device Manager under 'USB Controllers' you should have an 'NVIDIA USB Boot-recovery driver for mobile devices'

If not, uninstall the driver, reboot, rinse and repeat​

Unplug everything

Hold Vol Up/Down (and keep them held)

Insert USB cable

open command prompt

navigate to your NVFlash folder:

cd \
cd g2x\nvflash
nvflash.exe --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 5 recovery-clockwork-5.0.2.0-p999.img

You should see it send a bunch of files to the device and the phone screen should say "S/W Upgrade - Please wait while upgrading...". You can let go of the volume buttons at this point. Once the files are sent and the program is finished running in the command window, you CAN just pull the USB cord or be safe and just wait a few extra minutes, however it will still say "upgrading."

><><><><><><><><><><><><><><><><><><><><

To get into Recovery:

Plug the battery back in (or power off the device if it was on)

Hold Vol Down + Power until you see the LG splash screen with blue highlights (that means keep holding for ~10 seconds after you see the LG boot screen).

This is if you already have all the files and drivers set up:

How to flash ClockworkMod Recovery 5.8.1.3:

CWM Touch is still experimental. Flash at your own risk. Do not expect much help if something goes wrong or does not work right, be prepared for some crisis management.

Frequently asked questions:

Where do I place the .img files?

You place the .img files in the NVFlash folder you created PRIOR to flashing.

I'm getting an error.

You MUST keep both volume buttons held down the whole time until you get the success message in command prompt!

Try using a different USB port on the computer
