Question How to root and/or rom my device?

I have recently buyed a cheap device for tweaking a little bit around but i need root and on my Galaxy Note N7000 is it simple to root and flash roms!
But i havenīt a download mode on this device ( Polaroid PRO4006 )
So i cannot use Odin..
But maybe there is download mode but i cannot find it...

And then problem 2:
How can i root my device without computer because i cannot find download mode so i cannot flash Superuser...
Is there a one-click root apk available for Polaroid PRO4006 ?

Thanks...
