Hello, please do not fret, just search for DFU Tools. Of note, please use the right version of DFU Tools for your player (SP,TP,SL)

try the hard reset and after it plug in to your computer

After updating my Dane-Elec Meizu M6 with the last firmware (S2004.6) big problems. The player doesn´t work anymore. Only a quick white blink is visible, further totaly nothing (dead player). The computer doesn´t recognize the player so I cant´t do anything.
I need help. I read about special tools I can use??. Sent me all the things that bring my player back to live. Serialnumber: M6SP04GGJ3KDL1921.
