How can I update GPD Q9 firmware?

Hi.

I just downloaded the latest GPD Q9 PSV firmware image from the site.

How can I update the tablet?

Thank you.

Hi to upgraded the firmware you need to download Rockchip drivers 3200 I think drivers.  

then you need to download Rockchip batch tool latest version then download the firmware to your computer then extracted the firmware then you should get .iso image

Then after you installed the rock chip drivers then launch Batch Tool software on GPD Q9 device plug it into computer and turn it off completely and hold Volume + and Power Button at the same time.  

On Batch Tool should show green check mark then load up your firmware and click on upgrade.

Do not unplug the cord while updating the firmware or you might brick the device....

You upgraded the firmware....

thank you. where can I download the rockchip drivers and the batch tool installer, please?
