    Got it working on a generic M8S+ box. Tried flashing with TWRP, at first it kept failing and said ‘This is the m8s device not the N200’. Well a bit of ‘updater-script’ editing and the flashing went through. All seems okay, wifi & ethernet working, normal operations feels a bit smoother.

    The only problem that I’ve found so far is HDMI audio always starts out as disabled. Have to turn off the TV and turn it back on again to reset the HDMI audio signal. Or turn the box on first, and then the TV next. That solves problem with no audio.

    FYI, the wifi chip on my particular box is AP6330, boxes with other chip (BCM4335) might not play well with this firmware. Be warned.

    I have flashed this firmware with TWRP (dirty flash) and did not see any changes.
    But when i have flashed this via stock recovery (clean flash) i have found that hardware acceleration is enabled for all movie players (on previous firmware this feature was working only with SPMC and stock 4K Player).
    Futhermore i’ve noticed that Kodi Javis 16.1 that is installed with this version is modified and out of the box support AMlogic acceleration (Google Play version don’t support it), and Dynamic Refresh Rate Switching working without moddifing init.d.
    So i recommend to flash this firmware with clean flash and not update or uninstall Kodi.
    Don’t use Krypton – it has problems and there is no support for hardware acceleration for this box. My box has AP6330 chip. Hope this helps.
