  1. Does this firmware fix the problem with no video on older 720p only TVs.

    Have tried on over 10 older Tvs that were sold before 1080p was invented and none of them work.

  10. You are welcome 🙂

  11. I just received this product in the mail.. But i have a couple of questions if we flash the firmware will it erase all the settings on the phone back to default. I ask because I would want to does this first before setting anything up on it??? and then have to do it again

  12. The only way to FLASH the firmware is with a micro SD card.. So i can not use a THUMB DRIVE to flash it?

  13. Is there an App we can install on our phone so it can be used as a remote control for the M8 TV box?

  18. I received my M8 AMLOGIC S802 from Geekbuying. Everything is going like a charm but I have a little problem with the size of windows. It’s a little bit greater like my TV screen(Panasonic Viera) and I can’t see all the details in top and bottom. The size is setting NORMAL. How can I fix it?

    E: signature verification failed

  25. Is there any way to get this box to just boot to the basic Android screen like a tablet?

    There is some image of linux for the M8 TvBox? Or at least another image with a more natural main page of android. I prefeer linux.

  28. there is only linux xbmc for this model ( means you can directly boot to xbmc ,but system is linux) see it here:

  29. I have this Android box and seem to be having a problem with PowerAMP player. I thought is was just that app but now the problem also occurs outside of that app. When I skip between tracks I’m getting a loud noise that sounds like large metal table being dragged across a hard floor. Upon leaving PowerAMP to run Catlog Player it was doing the same noises each time I selected something. I have reinstalled Poweramp and I had also updated to your new firmware update above but still endure the same problem. The tracks it was doing it on were mostly 48Khz as the 44.1Khz were not doing it. Still – it did happen outside that app so any fix or advice?

  30. I’ve just received the M8 TvBox. I’m having problems with the 1080p playback in Netflix. Can this firmware solve this? The firmware I have is: KOT49H.20140807, kernel 3.10.33 ubuntu@ubuntu188#8. This is the last firmware?
