After a few hurdles, a great media center!

The hurdles:
1. Power supply
2. The update of the firmware was a little tricky
3. German keyboard layout for the external keyboard is only possible with a special app

The Solution:
to 1. An external Sromquelle is needed most, a USB power supply with 2.1A (when power is too low can cause failures in the form of restart).

2. The update to 1.2 worked for me only with a micro SD card I put in an SD adapter and had formatted (just the Micro-SD in a USB stick was not purely and format), the Forum for Rikomagic help (in some the update is already on it).

to 3. The German keyboard layout for my external keyboard (K400) I got only after you install the paid app "External Keyboard Helper," Again, the Forum helps with the settings.

Conclusion: If you invest a little time and struggles through the Rikomagic forum will be rewarded with a great media center.
