Can anyone help me install the OTA update on my Prestigio Geovision 7777 tablet?

I can't install OTA update on Prestigio Geovision 7777 tablet.

First of all, what is it for? I got a notification on my Prestigio Geovision 7777 tablet, that OTA update is available. It told me the instruction how to install it . I did everything it said but it failed.
Verifying Update package...
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted

I checked, there was an update.zip file on SD card.
Also it has this lying, opened android with red triangle popping out of it.

What's the problem and how could I fix it?

I know the problem, but I am not yet sure, if I know the solution, because I don't have the necessary OTA update.zip for my tabel.

But you can try the following instruction and start the update.zip then in the CWM-mode:

adbtoolkit.com/rooting/devices/freelander/pd10-pd20/Getting_root.pdf

I hope, it helps!
