Thanks GhostRider!
But it looks like i bricked my nvr completly before trying your files
Now it dosnt even boot from USB, only short bootlogo, few blinks from lan port and no other signs of life.
Probably only serial connection left - usb ports dont read flashdrive, lan port not working
BTW: are you satisfied with this NVR? Everything works fine? Can you recommend it?
Couse if i cant recover mine - i'll buy another unit.
Thanks for help!
