Firmware Version: Android Jelly Bean 4.1.1
Release date: 20.02.2013
Build number: crane_tvd_rsh-eng4.1.1
Today the MK802 series community is happy again: the reason is the newest Android 4.1 firmware release for Justop Android TV Box V2.0_REV1_Beta, thanks to Justin from www.justop.com/forums, as you can see next, this version can be installed also on our Rikomagic MK802II TV stick.
First, you can download the new firmware from here or from here. The method is just a little bit different till now: burn the firmware with PhoenixCard Tool on your micro SD card, insert it in your MK802II stick, power on and wait about 15-20 minutes; in my case the blue light didn't came off, so I turned off the power after more or less 20 minutes, took out the micro SD card, and then powered on the device. Try to use quality fast SDHC card to update. The firmware is much larger than ICS.
This version of firmware hasn't root acces, wifi is pretty unstable, Play Store work with no issues at all and the HDMI output resolution is only 1280x720. The main issue till now, reported by other users too, is the lack of any sound; there is no audio output... But remember, this is only a beta version; I guess that it will be soon enough a fix or workaround for that problem. Otherwise the system seems much smoother and faster than ever. I just love this version and I'm looking forward for a stable release. Thank you Justin, good job!
Always keep in mind that this is not a review, just a first sight of this firmware. You have to test it more for another details, to see if it satisfies your needs.
