My HTC focus 3 can not turn on normally. 

I turned on the glass and HTC logo show up, running in circle and nothing more. My VR headset is a used product, several days ago i turned it on normally and did setup but i was busy so i have not finished setup yet, now i turn it on and got this problem, i tried factory reset in download mode but it did not work. Do you have any other ways to help me, or suggest anything to solve? Please help me, thanks!
