Just my opinion I would not touch anything like smart switch or copy images of operating systems from any device to another ever, I've an IT background and I'm no phone expert but software like this causes nothing but problems.
I'd let the phone run out of battery and try and install the phone software via a PC, I've not done this before but google would give you all the info you need. Before that I'd try and uninstall every app that's not on the phone as standard just to see what happens.
If nothing above works send it back.
