So after reading all the post above:

-IPTV setting password is 3008. There's nothing inside here.
-Streamyx got lower res TV because it uses only max 2MB line.
-In my experience 2MB in youtube can only watch 360p or less without lag. Go Unifi if you want true HD.
-There's no setting to change the quality, but it will get better over time, not much to get that true HD.
-Press and hold power button to open recovery mode.
-There's a exploit out there to install Play Store via recovery mode, search "HyppTV Amanz[".
-You can install Youtube on using this Play Store but not android games since STB processor is slow and not supported.
-STB can play media from USB, with common standard format and codec (not too heavy like Dolby, DTS, FLAC, H.264 10bit etc)

anything I forgot?
