Hello,
I recently bought a second hand NVR Hikivision model DS-7608NI-K2 but I haven't any password. When I bought it, seller told me he didn't remenber password of unit, it was a good opportunity to have a good price but I couldn't imagine it will be so complexe ...
After looking some thread dedicated to recover password, I was not able to fix my issue !
Here is specifications of my NVR thru SADPTool

I tried to send same FW (NVR_K51_BL_ML_STD_V3.4.91_161220) and upper version on NVR using TFTP, not works, seems FW is not send to NVR, there is kind of loop, I never got "Transmit" still "Transmitting"

Right now I haven't any Hikvision cam's to try backdoor
Someone already get this behavior when he tried to update/upload FW ?
Thanks in advance for your help
Cheers !
