miniplayer black screen

while i heard musik yesterday, my miniplayer froze. i have often feozen scrrens. normally i wait until the batteri is empty or i install the firmware the seknd time.

so i connected the meizu with my pc. i wanted to load the new firmware on it and than it happend. the screen gets black and i hear no clicksound any more.
BUT i can still conect the meizu to my pc. i tried it with the dfu tools but i have the wmp usb mode aktivatet :-(
i tried all other recovery methods too

what should i do now?? i still love my meizu

EDIT: i cant copy any files to my meizu

juhu, he works again. i only had to waiut until the batterie is empty.

the best solution if you have an error with your meizu is, too wait until batterie is empty :-)
