WeTek Play 2 is the latest TV box from WeTek with DVB or ATSC tuner, and powered by Amlogic S905-H processor. It ships with Android 5.1.1, but Ubuntu 16.04 Mate and Ubuntu 16.04 minimal firmware images have been released by the community.
You can try Ubuntu 16.04 LTS Mate (with desktop environment) or the headless Ubuntu 16.04 LTS minimal image by uncompressing the images, and flashing them to a micro SD card with dd or Win32DiskImager. Two default credentials (username/password) are provided: wetek/wetek and root/wetek. This required the latest Play 2 Android firmware, so make sure you get the latest OTA update before trying Ubuntu. The Ubuntu 16.04 images should just boot from the SD card without replacing or affecting your Android installation.
If this type of images for Amlogic S905 seems similar, it’s because are based on Hardkernel ODROID-C2 Ubuntu 16.04 images. You can find the Linux kernel for WeTek Play 2, against a fork of ODROID-C2 kernel, on github. To build the kernel and modules, run those two command after having cloned the source code:
make -j4 Image dtbs modules
It’s unclear whether tuner support is part of the images at this stage.
