I'm using a Z7+ which was really working fine untill i've installed my infrared remote cable in it, since then the only way of restarting my device (which is always set in standby mode for my children on their favorite channel), but from time to time I prefer to fully restart the device for avoiding some problems. But from that point, the only way I've find so far for allowing the restart is to remove the IR remote cable from my Z7+.
My Z7+ is configured with my ethernet cable installed into it, an SDCard (16Gb), and the IR remote cable.
If someone have some information on how to 'bypass' that kind of problems that would be nice
PS : For all who are asking about Factory Reset ... It has already been done
Cheers everyone !
