My script is based on the process described in the Quectel docs. I thought these were already in the wiki but apparently not:

The 'CME ERROR: 505' is because the GPS is already off.
The 'CME ERROR: 418' is a failure to delete the file, which suggests it's the first time you've run the script since a modem reset.
I don't see anything obviously wrong, although it seems I didn't paste the output into my notes so I'm going from memory. How good is your view of the sky? I was testing from indoors by a window, and it was usually hard to get a fix without AGPS. With AGPS it was often very quick, but not always. When I was testing I kept modemmanager disabled and used picocom to access the serial devices directly.
I can't comment with certainty on a potential hardware error on the 1.2a boards as I only have a 1.1, but there's no mention of changes to the GPS antenna board layout.
