The Tronsmart MK908 is an Android TV stick with a Rockchip RK3188 quad-core processor, 2GB of RAM, and 8GB of storage. You can plug it into any TV with an HDMI port and hook it up to your WiFi network to stream internet video, play games, surf the web, or run other Android apps on your TV.
It sells for about $86, and it’s one of the fastest devices of its type that I’ve tested. Right now the MK908 ships with Android 4.1 Jelly Bean pre-loaded. But if you want to install Android 4.2, there’s an official software update. You can find download links and instructions at the Geekbuying blog.
Among other things, the new release resolves problems some users have had with audio and Netflix performance. The update should also let you use the RkRemoteControl app to turn your Android phone or tablet into a wireless remote control for the MK908.
If you want a little more control over your device, there’s also already a custom ROM based on the official Android 4.2 firmware.
Developer Finless from FreakTab has built Finless ROM 1.5 for the MK908. It comes pre-rooted, removes some of the pre-loaded apps to free up space, and includes a tweak so that even apps Google things aren’t compatible with the device will show up in the Play Store.
