In the event of system errors, software corruption, or display issues, recovery firmware files can be applied as a final troubleshooting step. By running the recovery program, the VMAX® A1 Plus will be defaulted and reverted to an older version of its firmware, resolving most operational issues. Once the recovery is complete, the DVR firmware can be upgraded back to the latest release.
