Maxim Shell

@Nick Aforgot to add, it has allwinner h313, also how do you backup or dump stock? I need it so I will be able to return if something won't work. Also thanks for help.

Also I need wifi.

@Nick AIt has only usb and hdmi, no any SD card slots. Also I dont know anything that it has, I just need graphics acceleration, sound and support of usb, its all.

Stock rom of this tv stick is so bad that it lags even with just watching youtube and it wrote it can play 4k. So I need armbian/any other linux distro for this tv stick.
