Getting Ready for NVFlash (~fastboot) w/Drivers

[djmcnz]

Okay,

So I suspect a few of you are going to want to jump on the NVFlash train that Paul is easing out of the station at the moment. NVFLash is the Nvidia utility for writing to the ROM on your Tegra2 phone, reading details and otherwise critical low level functions. For all intents and purposes this is akin to fastboot for many devices (although not the same as).

Whilst I'm not 100% certain I believe this is the only way to install a custom recovery on your Optimus 2x (when one is released) and therefore, if you hope to install a custom ROM, you will need to get NVFlash up and running.

Below are the simple instructions and links to the necessary files.

** 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. NVFlash can not physically damage your phone but it can render it inoperable. 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 requiring factory maintenance. Warranty coverage for your phone is not assured after using NVFlash. Please proceed with the use of the tool carefully and at your own risk. Neither myself nor XDA-Developers can be held accountable for any consequences from the use of NVFlash on your phone.​

Get Software

1. Grab the NFVlash utility from here: http://djmcnz.batteryboss.org/stuff/NVFlash.zip
2. Extract the contents of that archive to a single directory
3. Grab the NVidia boot-recovery driver from here: http://djmcnz.batteryboss.org/stuff/nvmobileboot.rar
4. Extract the contents of that archive to a different directory

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 to 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. Navigate the the directory you extracted the NVFlash archive to
2. Run a harmless command such as "nvflash --sync"
3. 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

   dk burned: false
   boot device: emmc

If so, you're good to go, now just be patient...

It says that you didn't specify/ provide bootloader.bin file in the command line. Find nvflash ROMs thread and compare the command lines.
