My X 'cannot upgrade at this time' after downloading and rebooting, doesn't sound like I'm missing much but I like to keep up to date.

I haven't messed with the software so is it possible there's something wrong with my device? I only ask because it was in my pocket during a bike crash so the frame is cracked on all sides and there are colour marks on the screen, but other than that it seems to work perfectly. I don't know of any diagnostic tests in Sailfish.
