I have the ViewSonic gtablet and I was trying to install VEGANn from here
This wasn't working so I reset the gtablet to factory settings and it is now stuck at
"Booting recovery kernel image".
I wanted to try NVFlash found at http://forum.xda-developers.com/showthread.php?t=861950
but this part is a problem:
The NVFlash setup process begins with a visit to:
(Note: Sometime this DropBox is cranky. If you have trouble with it, check back later.)
Linux users: You want to get "nvflash_linux_2010110500.tar.gz" and "nvflash_gtablet_2010110500.zip "
I use Linux Mint 9, a derivative of Ubuntu 10.04
