With too-new firmware on V1 hardware you've become a test pilot. Perhaps as bigred says it's not bricked in the sense of totally dead, but rather some things don't work right and maybe others do. I'm running V4.001.0000000.3, Build Date: 2020-05-19 on the V1 hardware. Perhaps that version is online somewhere and you could try going downward to it. You can't roll back indefinitely. The release notes for my version say:
This new baseline version is based on the version of Security Baseline 2.1, and it can be rolled back to the
versions after Security Baseline 1.4, but cannot be rolled back to a version prior to Security Baseline 1.4.
With even newer versions the restriction might be worse.
