Take a step back, take a deep breath, and patiently look / reconnect connectors underneath your playfield and in the head. The software upgrade will not introduce your problems as it appears you have something going on with your hardware. With a clear head just go over the connections, reseat, look at connectors and cables, and there might be something you see or something that you don't see and fix it. Look at everything and everywhere. Your machine traveled a long way. Things happen during transport unfortunately.

Tech alerts are gone. Left orbit is not software. Sound glitches (cutting in and out, especially at start of power up) is the SD card. Upgrade and you will be fine.

I had immediate 2 failures and then switched to a different memory stick and it loaded successfully. I was always using the same file downloaded from stern. I also use windows and always make sure to safely remove the stick from windows.
