Unhappy [Q] SMP600 encyrption won't go away


My Samsung galaxy tablet 10.1 2014 wifi addition (smp600) is not getting passed the encryption password page on bootup. I tried to wife everything and install a new rom and that did not work. I also tried to format the data and install rom and that did not work. Every time I try to enter the password it either reboots or sits in the android encryption logo. I have also tried different roms to see if it fails for each and they all fail. If somebody could teach me how reset the device so it isn't rooted or have twrp that would be great. Also I think it needs to be repartitioned but I'm not sure. Also I cannot find the United States stock firmware for the device. Without that I probably can't attempt to restore. I have not tried Odin. But i NEED the USA stock software!!! And i need and odin tutorial. Since it is a wifi tablet do I need to have the U.S. Firmwire??
