Zidoo X9s can not boot up

Hi I am on X9s with firmware V 1.2.7 , I am having issue with X9s totally can not boot up , the back power is ON , so I try to power off and on again , this time the X9s power up with stay at "boot " label only on X9s display. I Off and on again , then boot up normally. On second day , I try again with on the X9s , same thing the X9s cannot boot up . I off all power for few hours , this time can boot up , may I know what is causing this issue?

 

try a reflash.

 

FYI , I has try with flash the X9s , the boot up issue okay for 1st time

 

you did not have this problem with older firmware ?

 

I has try re flash , but okay for 1st boot up , I turn off the X9s and power off power plug , and I turn on again after 5 minutes, my X9s again does not boot up at first time, and I had to on and off the back power few time , then boot up normally.

 

Yes with V1.2.6 I have no issue

 

I maybe flash back to V1.2.6 to try out again.

 

Is New firmware can cause the boot up issue ?

 

With V1.2.7 , I have issue with the boot up hang with " boot" display at X9s display, and nothing display on my Tv.

 

Above issue is occasionally.
