since nobody answered u there, let me comment here in a more appropriate thread.
himedia q5ii is a well made android box, despite it being 6-7 years old.

if u can tell me what firmware it is on and whether it is an emmc or non-emmc unit, i can say a bit more.

in short, what it can do, like the current q10pro/q5pro:

.. popular apps like youtube, spotify, terrarium, mobdro, tvplus2.0, icdrama rss player, popular "china" vod apps, "ahem" iptv apps.
.. playback of 1080p incl bdmv, dd, dd+, dts, dsthdma; may not do ddtruehd.
.. kodi 16 jarvis.
.. wifi 2.4ghz 50ft.

what it cannot do:

.. hevc (h265), 10bit, 4k, HDR videos.
.. astrogo, unifi playtv.
.. kodi krypton 17.6
.. wifi 5ghz.

these, u need the current Q models.

do not junk q5ii unless u have gone 4k, hdr and dtsx/ddatmos!

this model is an emmc model, a better one than the earlier nand one, i.e. faster.

however, the storage of 8gb... less opsys, partitioning, etc... not that much available for use.

i would advise u to stick to simple apps and not install large complex ones like kodi or torrent based ones like popcorntime.

if u install too many or big ones, the box will get sluggish, even hang.

what i wrote in previous post is based on this box which i have one too.

i am using it mainly for playback (max 1080p) and a couple of apps.

last thing - u did not mention the firmware version - u can see it at the same page u found the rest of the info... "HMD 1.0.9...."

if it is not the last one 1.0.9, best to update.

but will be difficult to find it now - this model is not supported since 2014.
