Hi All, Black Diamond Model: PDR-XMR3004 don't know the password and tried default (123456), and mostly available password but no luck. I took out the cell in there and after 24 hrs. dvr date changed to default time and date (01/01/2000) but still password issue is there. opened this box because it was with the wrong dates. Google even can't help in this, no manual available online / youtube also doesn't have any video for this brand. Please help. Thanks
