The specs I found online suggest it has the SSV6051P WiFi chip. If true it is not supported and won't ever be - we have sources for the driver but they are ugly code (easily the worst legacy driver code we've seen) and will not compile on any kernel newer than Linux 4.11 without a major rewrite that nobody sane is going to volunteer for. Plan B is to use a USB WiFi stick (avoid Realtek ones). Plan C is a WiFi bridge that presents Ethernet to the box via a short cable. I use an old Apple Aïrport express like this during board/box testing as (even with boxes that have supported WiFi chips) it eliminates the need to configure WiFi to get online.
I've no idea where the reset button is, but the normal locations we see with cheap TV boxes are either between the air-holes/grille on the underside of the box, or down the bottom of the 3.5mm AV jack.
One of the USB ports is probably an OTG port that can be connected to a PC to flash the eMMC with an Android image via Amlogic burning tool .. but I have no advice on what image to use.
