Prestigio MultiPhone 5430 and nonexistant boot/recovery partitions
While I am not nearly as well up as you, I haven't seen any replies and this might be of interest - if not to you then to others looking for info on Prestigios. 

I have a Prestigio PAP 4500 Duo which bricked itself spontaneously on New Year's Eve, sleeping the sleep of death. It's under guarantee so all I was looking for was a possible reboot mechanism. I happened upon this menu which seems to offer lots more than you described. Now I couldn't navigate the menu, but that may be because of a fault, but the menu is there to be accessed.

Thanks for your info and hope this adds a little,

MJF
