Does anyone know why my Arnova 10b g3 is not booting up.

After i had downloaded a recent firmware through the tablet, all has been fine and working well and to my delight i had no problems with it. However i tried to use this recently and it will not boot up. I get nothing. Not even a green light saying its turning on or a Arnova display on screen as it boots. i charged it fully till there was a green light then tried to boot it up again and no joy.

I looked on many forums and it suggested doing a system update or add the original firmware using my computer and Rock Chip application. I followed all the instruction, on how to load up the tablet using power cable plugged in and usb from computer to tablet and point a relevant driver to suit my computer operation system etc etc etc....

It took me a while to work it out but i managed to get rock chip tool to recognize my tablet and usb drivers and perform a firmware update which i also downloaded, and it seemed to work its magic loading the firmware and installing it, but it still wouldn't switch on and there is no display. I checked to see if the tablet would connect to my PC and it does it recognizes it no issues, and i can transfer songs and files etc to the tablet and it is present, when i check through the PC. I just don't really understand.

Has anyone else have any ideas? I have reached a brick wall and pretty much give up with the bloody thing. Oh yeah, if its bricked, am i just banging my head against a brick wall for fun or is there hope?

Please i look forward to any suggestion to help resolve my problems and look forward to trying new things.

Thanks
