Android 4.4 Kitkat Beta Firmware for Ugoos UG802 mini PC (Rockchip RK3066)

When you purchase a Chinese Android gadget, or most Android gadgets for that matter, you expect to have a few firmware updates within a year or so at best. But to my surprise, Ugoos has released an Android 4.4 Kitkat (Beta) firmware for their UG802 mini PC / TV stick that started selling in summer 2012 with Android 4.0.

Ugoos_UG02_kitkatThat means your “old” device(s) could get a performance boost, as well as some neat new features, thanks to Android Kitkat. The firmware is beta however, so be aware that there may still be a few bugs.

The firmware file (Allminipc_ug802_RT8188_4.4_720p.img) is packaged together with RKBatchTool and the Windows drivers in Allminipc_ug802_RT8188_4.4_720p.rar. You can follow RK3188 firmware update instructions, skipping the downloads since everything you need is included, to perform the upgrade. If you’d rather use Linux, you might be able use upgrade_tool, enter recovery mode, and run:

sudo ./upgrade_tool lf
sudo ./upgrade_tool uf Allminipc_ug802_RT8188_4.4_720p.img

One of the main differences in terms of hardware between RK3066 mini PCs is the Wi-Fi module, so if your TV stick also comes with a Realtek RT8188 module, the firmware above might also work. Bear in mind that flashing the wrong firmware to your device may brick it, and render it unusable.

Beside UG802, Ugoos also plans to release Android 4.4 Kitkat for UG007, and the popular MK808B HDMI TV dongles.

    Is it compatible with the iMito MX1?

    @Bernd
    Wi-Fi won’t work with this firmware.
    MX1 has a Mediatek MT5931 Wi-Fi module – http://www.freaktab.com/showthread.php?5165-Internal-Wi-Fi-Chipset-of-TV-Sticks

    @cnxsoft
    Based on this list, Minix Neo G4, and Rikomagic MK802 III might work.

    This thread – http://forum.xda-developers.com/showthread.php?p=53095190 says that it can be installed on MK802III. Can someone confirm that the wifi will work on MK802III w/ this firmware because I think the wifi chipset on this is different from the UG802.

    Anyone that can release/build RK3066 MK808B RK903 kernel with the following GPIO pins?
    https://docs.google.com/spreadsheet/ccc?key=0AlY8Ntc7De3adEgxZEw3eWF1cmZBbTdtMmQxNThBdGc&usp=sharing#gid=0

    Wake up pin for wifi
    rk903_26M_wake_host – RK30_PIN6_PA7 , GPIO Number 359 (Pin 5 was missing on Jellybean source, don’t know how it works in KitKat, if not the same then it’s GPIO number 282)

    Can you give more information about this ROM and kernel? How is video playback and Wi-Fi speed? Is it stable? Is it smooth? All firmwares I’ve tested on my Minix Neo G4 (Finless 1.7c, digitopMod, Lewy HFW, official ROMs, etc.) have a slight microstutter on every goddamn movie. I want to try this one, as it should theoretically work with my Neo G4. Please, share as much details as you can. Thanks.
