Wrong version firmware update...

[newlook 0]

I just flashed the firmware of my dvr-4cif .. model 36574v.. no brand.

original firmware was va1.2.8

with the original it was not possible to view cameras on internet..

updated with version 1.3.0 km worked fine ... internet access was possible but login failed every time.. on mobile gave error id not recognized

so again flashed with version 3.3.0 km flash completed and now no boot ... it turns on ... hard disk running but nothing on screen...

 

is the unit ruined... or is there any possibility to reflash it

any solution plz...
