[jwarrior 0]

Hi,

 

i need some help with my super mini NVR 4ch .

 

I tryed to update the system but the power of my house was down before the update ends.

 

So now i only have the main logo when i start the mini nvr and he shows always the main logo i think he can´t boot, i attached the picture.

 

Can someone help me how i do to reset or recovery the mini nvr?

 

The only way is with Tellnet? i am not IT expert can someone explain me sending a video with instructions or the steps?

 

I wait for help.

 

Thanks
