Just did the update last night, it was simple. Boot the tablet into windows mode and download the new bios update.

Unzip the file and run the update.exe. It will auto update without having to do anything else. After that it restarts and it is all fine.

To flash a new firmware for the v919, you need to put it into DNX mode (see instructions in the v919 forum).  This used to be done by pressing both vol up/down and power at the same time when booting, however with the new BIOS, this action brings you to the OS selection menu.  So I need to know how to flash new firmware ie. how to get into DNX mode.

Ok I have this version odd the boys installed

I think this is the latest bios, and this still does the ndx mode. You have to be booted into.android first, then the button combination well bring up ndx.

Thanks!  I already had that BIOS version but somehow it didn't work or went about it wrong.  I managed to do it by booting into android, then pressing all three buttons until the OS choice menu popped up again.  Here I then just pressed on Vol+ for a couple of seconds and ndx mode came up.  I have now also flashed the new firmware, so all good.  Many thanks for your help.

Great fourm, I have a Onda V820W tablet, and I download the BIOS update, unziped it, ran the update.exe, updated completed.  I rebooted, now tablet will not boot, but does flash the LED quickly.  I did make sure I was fully changed and plug in power cord.  I can see the backlight is on but no video.  I hold down the power button to turn off tablet, and try to turn on the tablet and the same thing happens.  I did hold down the Volume up (+) button and power button, but I get the same thing, LED flashes quickly and the backlight turns on and thats it.

 

What can I do to fix this?

With the help from member jackbauer, I was able to use a HDMI cable hooked to monitor, and was able to see my screen.  I then installed the right firmware, and now my tablet is back to normal.
