Why don't you use the search button? You have to reload the firmware to your Miniplayer, the latest one is here:
2.004.6 Official Release SP\TP\SL
Extract the files in the firmware somewhere in your computer, go into the newly created folder and copy the two files to the root of your Meizu Miniplayer, so they appear beside the folders. Do not copy them inside any folder.
Now disconnect your MiniPlayer and let it upgrade. After that, follow that forum post to get the user interface back to English from Chinese.
