S705 Firmware Issue

Running into a crazy issue with one of my S705 endpoints. If I try to install firmware (via the EPM) greater that 2.0.4.67 the graphics have major issue (see attached photo) and the phone goes into a infinite loop of rebooting. If I roll the firmware back to 2.0.4.67 the graphics return to normal but SIP registration fails. I’ve tried both x.4.72 and x.4.73 firmware releases and get the same results with both. Only a full factory reset and rolling the firmware back to .67 will solve the issue.

Any thoughts on what the issue might be?
