hello plz i have a problem

and I want to know in what section I post my question, I put it here for some administrator to move it. /// I have a hikvision DVR 7216HUHI-K2 which had the firmware DVR-K71_-ML_STD_V3.5.37_Build_180928.zip After doing an update via USB with the DVR-K71_EUROPE-ML_STD_V3.5.50_Build_180124.zip after turning back the dvr I am left with the menu without USER and does not respond well to the menu. then I am trying to by means of TFTP and SERIAL to place the old firmware I leave here log how I do it. and the error that it gives me.

before , the HKVS#
when typing update or help nothing happens .. only when I put it directly

setenv ipaddr 192.0.0.64
setenv serverip 192.0.0.128
setenv bootargs console=ttyS2,115200n8 root=/dev/ram0 rw initrd=0x42000000
setenv bootcmd 'tftp 0xc0700000 uImage; tftp 0x42000000 digicap.dav; bootm 0xc0700000'

You can't boot a digicap.dav fiirmware file.
Best to put the environment variables back to the values they were originally at.

Then with the tftp server running, try this command :

setenv ';update'
or
setenv ';upgrade digicap.dav'
