    Downgrading from Kitkat to Jellybean

    Paul Ronjak

      We had some MC40 Kitkat devices that mistakenly had the Jellybean FullFactoryReset zip ran on them. We're getting a certificate pinning error when enrolling into our MDM and wanted to test downgrading back to Jellybean, factory resetting, then upgrading back to Kitkat to rule out any complications from the wrong factory reset. When I sideload the zip the MC40 throws the following error:

      "Verifying update package...
      Checking hardware...
      Stop update. check_hw() return false
      Installation aborted"

       

      Any ideas?
