Android lollipop 5.1 on my Cubot P7

[Computers12345]

I want to update my Cubot P7 to android lollipop 5.1, but I cannot find the update.zip file to do it. Can someone help me.

I also don't understand all this flashing roms and whether I have to do it.

I doubt you'll see any version of lollipop on that phone.
