[G Tablet General] butchconner:
Windows NVFlash Info....

Following this is a long doc where I tried to describe what I did to NVFlash my ailing tablet from Windows -- plus giving a possible source for the USB driver.

I sent this to Roebeet to help with his "official" nvflash stuff. But if several of the rest of you need this info I will paste the rough draft below in case it would help you.

****************************************

NVFlash from Windows 7 64-bit

This document is to clarify the procedure for using NVFlash to install stock software on a ViewSonic G-Tablet

after a malfunction which makes the normal recovery process impossible.

First thing is to check and make sure your G-Tablet is ready and can use APX mode. Push the "Power" button

on while holding down the Volume- rocker down. You should get a kind of dark gray screen, but after a few seconds it will turn black with no indication anything is going on. You should be in APX mode. You can shut down until ready to flash.

Next, gather the software needed. Go to Roebeet's Thread on using NVFlash to restore your G-Tablet and get

the software needed to NVFlash:

nvflash_gtablet_2010110500.zip

nvflash_windows_20100500.zip

The file with "gtablet" in the middle provides the tablet software, and the file with "windows" in the middle provides nvflash and related files.

Once you have downloaded these two files, go the the Advent Vega software download site and get the Advent

Vega file:

SystemUSB.zip

This file provides the USB .inf file and the drivers necessary to allow USB communication with the G-Tablet in APX mode.

Now, create an "NVFlash" (without the quotes) folder on your C: drive of your Windows PC. The extract the two nvflash .zip files (gtablet and windows in the middle) into the NVFlash directory. Then, copy the extracted "SystemUSB.zip" folder into the NVFlash folder.

Now you are ready to actually flash the files to your tablet, so turn it on using "Power" and "Volume-" to go into APXs mode with the black screen. Then hook up your USB cable from the mini-USB port on the G-Tablet to a USB port on your PC. The PC should respond by trying to install the APX USB driver -- but it will fail because it doesn't know where to find the .inf file and driver.

Click "Start" on the PC and go to Control Panel and then to Device Manager. You should find the APX device listed with a yellow "!" exclamation point on it since it didn't install right. Then click on APX and look for the "Update Driver" button. Click the update driver button and then choose manual search and use

the browse button to find the Vega_SystemUSB folder to point the search to.

When you tell it "Next" and move ahead, it will ask about installing unknown software and you tell it to go ahead -- and it should finish the install successfully and tell you so!

Assuming you have all the software in place, you should go to the NVFlash folder and run:

nvflash_gtablet.bat

It will open a black command window and you should see it loading the various software component onto your G-Tab. It's a good feeling to see it come back to life! When the flashing is finished it will reboot and you should go right through to the main screen.

You will need to click the Notification Button on the upper right hand corner of your screen to turn off the USB stuff. Then you can click the USB "Safe to Remove" icon on your PC's tray -- and you can disconnect

the USB cable.

The software used in the restore is old, old, old -- so you will want to use regular procedures to install a newer, more functional update.

Personal comment: I have two G-Tablets and have worked like a demon to avoid having to flash anything since I started last November. But once I had the right files and a general idea of what to do.....it really wasn't that bad.

Good luck to you. I hope this narrative helps you.
