I can't change the MODEL on my 8s!

For some reason, it's just stuck on MCPX. I don't know what's going on. It's like the top of my touchscreen where the model name goes is completely dead. Which brings me to a second question - are the buttons supposed to work with Deviation? The only times that mine work are when I'm either upgrading the firmware (EXT) or in USB mode (ENT) So I can't just use the buttons instead of my touchscreen if the screen isn't working?
Thanks for you help! I appreciate it...

Just want to add that I tested the touchscreen and that area works. I just can't get it out of MCPX. I even re-upgraded the firmware again.

Okay, I feel like an idiot. I figured out how to unlock my buttons, duh... So I was able to change models, but I still don't get why I can't change it with my touchscreen.
But thank you!
