Chinese KitKat

[geoffrey mendelson]

I have a Chinese Android tablet. It is  a Kaya 10.1 inch tablet 
purchased from Office Depot.

I can't find a website for Kaya, and Office Depot has closed, so tech 
support is as far as I can tell nonexistent.

It's running Android 4.1, which just upgraded itself (no details on what 
was upgraded were given), but has no search for upgrades option.

Is it possible to upgrade to a generic version of KitKat? One of the 
reasons I would like to update it is that the operating system is 
customized for the hardware. It has a regular type A USB port for OTG 
devices, but only has drivers for USB storage. I want to add bluetooth 
(keyboard, headset), USB headset and an SDR dongle. :-)

If so how? Is there an English step by step tutorial?

Geoff.
