Just turned on my Helix LT and I'm having the same problem. It's been a while since I updated to 3.15.0 and it wasn't even connected to a computer. I had been using it for months with no issue and this time it displayed the "Updating UI MCU Firmware" message with the -7 in the upper-left corner and it never progresses. Odd that this would display when it's been working fine for months with no update applied.
