Hi, I just bought BTR7 from amazon store, few days ago.

I installed Fiio Control and tried to update firmware from 1.71 to latest 1.95 , but when everything has been downloaded and installed, then restart shortly,  update fails.  I tried 4, 5 times with different cables too but doesnt work.

I tried to update from online and locally, but it always fails after restarting step.

please help.  

thanks. 

Jeff
