I just received my unit a couple of days ago, proceeded to install the latest BIOS and Android firmware with no issues. The tablet is surprisingly well built and the OS switching is flawless so far.
Been searching the internet for information on how to root the Kitkat install, so far have turned up nothing, does anyone here knows how to do it?
Thanks everyone for the various tips.
SOLVED - Found the following instructions on XDA.
Choose T3 as the root method, works like a charm, make sure you have the drivers installed (from Kitkat firmware update package downloaded from the Firmware section)
UPDATE #1: Root is holding up well, do not install Xposed Framework, it will freeze the boot process and you will have to do a factory reset using the above to access the CWM recovery. So no Greenify at this point.
