Firmware Update failing verification

Attempting to upgrade the firmware on a M4350 12x12 sw from 14.0.6.19 to 14.0.9.10 and the downloaded .stk file is failing signature verification. Verified checksum is good. Any ideas on how to update to this firmware version?

    Have spotted the potential manual boot code update requirement from the release notes?

     

    Known Firmware Issues:

    • The boot code might not update automatically when upgrading to this firmware because the firmware size has increased.
      Workaround: Update the boot code manually, or upgrade to the same firmware version again.
