Mars 5 powering up stuck on "100%" screen

My Mars 5 was not recognizing any USB I inserted and previously it was powering up but going nowhere. After installing the new firmware via formatted USB it began to work again, however it is just stuck on the "100%" green lettering screen now after trying the same thing as a resolution to the issue with it not recognizing any USB stick.

Any help is greatly appreciated please I am working on an important piece.
