There seems to be a lot of MXQ Pro's showing up with more different issues than any other box.
The whole boot freeze issue is not, completely, resolved. It's not only MXQ Pro's that still have issues, I have a MiniMX that occasionally stalls at boot using the disabled build while, on the other hand, I have another MiniMX (same specs) that rarely freezes using the normal build.
Disabling the Temp sensor has dramatically improved the issue, but not resolved it.
