NVFlash is for use on Windows PCs.
Excellent details on how to set up NVFlash are available in this topic (thanks jmcnz), but in a nutshell the process is:
Download the ROM file below
Download the driver file below
Turn device off, remove battery, plug device in while holding volume up and down - screen will stay black but Windows will add a new 'APX' devices
Install drivers extracted from driver file download
Run 'flash.bat' from ROM file download
Wait for flash to complete and device to reboot
The all important files...

Thx for the help.
tried to restart by pressing down power button and volume for more than 20 times.
it boots as normal, evrything is working, just the android market not working.
Can i go n press factory reset to reset all the setting even the software into the factory setting?
I really am a noob in these.
