A nice TV Box that uses the Amlogic S905 SoC.

This TV Box runs a modified Android 5.1.1 OS that didn't seem to be updated at all by the manufacturer, it also includes many proprietary (and PUP) software.

Luckily, the KII Pro uses an Amlogic S905, which has some support in the mainline kernel. Even better, a DTB made specifically for the TV Box is also in the mainline kernel. As such, some GNU+Linux distributions support this TV Box with many other Amlogic-based TV Boxes.

Armbian and Manjaro ARM have been tested on this TV Box and are known to mostly work.

This TV Box could make a nice mostly freedom-respecting media center, powered by postmarketOS.

Beaware of clones and different versions

There were multiple clones of this TV Box, as well as different versions.

The 2 known versions of the KII Pro are the VideoStrong KII Pro (the version this port is made for), which uses the Amlogic S905 SoC, and the newer Mecool KII Pro, which uses the Amlogic S905D SoC instead. If you own the Mecool KII Pro then this port won't work there without some changes. It may work by using the right DTB file though.

There's no guarantee that the TV Box used for porting postmarketOS will be the same as the one you have.

Contributors

Users owning this device

  • FerassElHafidi (Notes: Wiped eMMC. Amlogic secureboot not enabled. Now only boots Amlogic firmware from an SD card. pmOS installed on SD.)


How to enter flash mode

Still have to figure that out. Not needed unless you bricked your TV Box

How to enter recovery mode

Also not needed. Press the reset button once while booting.

Installation

Only installing to an SD card works currently.

$ pmbootstrap init # manufacturer: 'videostrong' codename: 'kii-pro'
$ pmbootstrap install --sdcard=/dev/mmcblkX # change 'mmcblkX' with the path of your SD card

How to boot other OSes from an SD card

Unplug your TV Box's power supply. Press and hold the reset button while plugging in the power supply. Keep holding the reset button until a picture shows up on your screen.

postmarketOS should boot up.

What works

See the device status at the top (mobile) or at the right (desktop).

LEDs

LEDs are functionnal. Use /sys/class/leds/red:status to control the LEDs. When setting the brightness to 1, the red LED will turn on and the blue LED will turn off and vice-versa.

DVB Tuner

The DVB tuner is untested.

TV remote

The TV remote works only for powering on the device sometimes. It doesn't seem to work in postmarketOS It doesn't seem to work on the vendor firmware anyway. Needs more testing.

Wi-Fi and Ethernet

Wi-Fi's broken.

The TV Box has an Ethernet port that works in Manjaro ARM and Armbian, but it doesn't currently work in postmarketOS either. Again, it needs more testing.

FOSS bootloader

The KII Pro uses U-Boot as its primary bootloader. It would be nice if we could load a mainline U-Boot.

TODO: Figure out how to compile U-Boot for this device.

Audio

Needs testing.

Hardware acceleration

Seems to work! Weston runs fine on the device and the postmarketOS demos work fine too.
