  • The error message 'failed verification on /data/datafs.tar.gz' should only occur when upgrading to v7.0.15 from any version lower than v7.0.14 once skipped the upgrade path and upgraded directly to v7.0.15.
  • Before upgrading to v7.0.15, the system has to be on the base of v7.0.14.
  • If the device is directly upgrading to v7.0.15 from any version lower than v7.0.14, roll back to the backup image from BIOS to fix the problem.
