Onkyo NR7100 Firmware Update Broke My Audio

Hey everyone, I am having an issue with the firmware that just updated and its extremely frustrating - hoping someone has some insight.

Basically after the update, my audio in my front speakers has dramatically shifted to the right speaker. I did a factory reset, recalibrated numerous times with both the standard mic on the receiver and with a UMIK-1 on my computer and the same results every single time. Even if I add more volume to the left speaker, it still sounds very off and frankly not very good. I cant get any center image without the right speaker overpowering the left.

I cant find any way to go back to the previous version and I cant re-flash the firmware either. I have sent a support ticket to Onkyo but in the meantime, I cant use my system without pulling what little hair I have left out because it sounds so terrible...

Any ideas?
