Stuck on boot screen of "quick boot" app

[Zerobabel]

Hi. I have a Dany genius tab (I hate to even see such a name lol )
I rooted it nefore a while, and to make things easier I installed "Quick boot" from gplay.
I made a backup, and then instead of pushing "reboot" I accidentally pressed something else.

Now it says: "Now send the package you want to apply to the device with "adb sideload <filename>. No matter what I press no other options appear!

I have the andro studio installed plus other dev apps (I'm just starting to get into andro dev) but I JUST want to reboot it.

Is it possible?
Or do I have to connect it to the pc and run a bunch of coms?

Thanks in advance, I wish for a quick reply to this bummer..

Well I'm sorry. Finally I jus had to press the start key for a few secs more

Take it this means you are sorted now? You probably booted into Bootloader mode by the sound.
