Prepare Phone
1. Power down phone
2. Remove battery
3. Hold VOL_DWN+VOL_UP & plug in USB connection from computer
(note, your phone will not visibly respond but it will boot to APX mode quickly)
4. Open Device Manager in Windows and you should see "APX Device" listed with an error
5. If not, rinse and repeat Install Driver
1. Right click on the APX device
2. Select 'Update driver software'
3. Select 'Browse my computer...'
4. Select 'Let me pick...'
5. Select 'Have disk'
6. Browse to directory you extracted the *driver* software to above
7. Select 'NVIDIA USB Boot-recovery driver for mobile devices'
8. Accept any warnings, including the big red alert (you may need to disable UAC)
9. Now in Device Manager under 'USB Controllers'
you should have an 'NVIDIA USB Boot-recovery driver for mobile devices'
10. If not, uninstall the driver, reboot, rinse and repeat Testing
1. Make sure your phone is still plugged in to the computer! (some people, wow.)
2. Navigate the the directory you extracted the NVFlash archive to
3. Run a harmless command such as "nvflash --sync"
4. You should get something back like:
Nvflash started rcm version 0X20001 System Information: chip name:
unknown chip id: 0x20 major: 1 minor: 3 chip sku: 0xf chip uid:

: 0 Update 27/04 Okay,
now that the G2x has been released there are different procedures from this point on
to follow to flash the O2x and G2x back to stock. You must look in the appropriate
forum to download the necessary files as well as the command line script.
Tip - For Reading This Far One of the things you may want to do after flashing your phone is
install a custom recovery (e.g. ClockworkMod). Many, many, many people try and fail to boot
their 2x in recovery mode and spend endless hours wasted. So, it may save you some time
to know the following.
To enter recovery mode use the following procedure but BE WARNED :
If you do this BEFORE you install a custom recovery you will factory reset your phone.
This is because it will boot the stock recovery image which auto-wipes your device.
Hold VOL_DOWN then press & hold POWER Keep both pressed UNTIL
the recovery menu appears then release POWER then release VOL_DOWN
The menu text in ClockworkMod Recovery is orange if you get a green menu or
a message that your device was reset then you're not running ClockworkMod... sorry.
