Upgraded to android 7.1.1 no signal

#1
HI, i decided to upgrade my U9-H from the marshmallow to Nougat today but every time I've tried to connect it to my 4k tv I get no signal ive tried all 4 HDMI ports and different HDMI cables. If I downgrade back to marshmallow I get a signal again on the same 4k tv, strangely if I connect the minix to a 1080p tv while running android 7.1.1 I get a picture does anyone know how to fix this issue please

Hi & welcome Jason1984,

Obviously, Android 7.1.x for the U9-H is still in beta & it is clearly labelled as such!! You update to it at your own risk at the end of the day ;). There are no guarantees & problems such as those you've experienced are inevitable in some cases. The beta firmware still has several known & possibly unknown issues.

Ultimately, stick with 6.0.1 until there's an official final release of 7.1.x ;). 6.0.1 is very stable & reliable.

Enjoy the U9-H :).

Hello. Are you using the latest firmware in your tv? If not i advice you to do it .
Stick also for now with Marshmallow minix firmware.
Welcome and enjoy your box.
