himedia q5-11 android upgrade

[hj555]

hello, i believe i have  a himedia q5-11 but the logo is not there and has an iptv service logo on it instead. it has the exact same design and ports and is running 4.4.2. every time i turn it on it goes to the iptv reconnection fee but i can use it as a android box by pressing the home button. does anyone know any firmware where i can upgrade android on it?
its the version that has a sata cable

If it's running Android 4.4 then it's previous generation Himedia Q5 4K3D / Quad. See here: https://www.futeko.com/newforum/index.php?board=2.0

You can try installing the firmware at the above forum, but I suspect the bootloader will be locked to whatever IPTV provider has licenced the hardware from HiMedia. I know of no way around this.
