hi all had a working sd32m60, set up mobile app, which wouldn't control ptz so thought just as well try to upgrade to the latest firmware. have all the files tried almost everything, in the end we replaced the hard drives, now have a 2tb primary and 1tb secondary, have tried everything, dm have been very helpful, but all seems to point to me having screwed up either or both of the bootloader or the NVD0, any ideas? thanks in advance badger2012
