You are going to have to lose data and do a Hard Reset with the button push method. Nokia Lumia 920 hard reset

If that does not solve your issues (the non-boot and the "stucked" screens) then you will have to flash the OS and Firmware with a clean copy. FAQ - How can I recover/reset/restore my phone software? - Microsoft - USA
