@Ari

Hi
Youtube on our H1 projector did not work very well so We downloaded that patch you recommended. Unfortunately our projector frozen up during the upgrade.
We were trying to reboot it from usb. I mean We kept button "play" for few second etc. Projector could see the usb and is showing message: " do not turn off..." etc but it keept freezing up every time.
Our projector does not work at all right now. We are not able to go into the menu.
Any advise

Hi how long should takes the upgrade?
