Finally got it to work. Pulled an older laptop out of the closet (with Win 7 x32), hooked it to a mini-switch, setup TFTP Auto-Update from Hikvision, set the IP to 192.0.0.128, disabled firewall and AV. Powered camera from external power supply, it did the check on port 69, then the downgrade to 5.1 took place. I then upgraded to 5.1.6 from the web gui. Thanks guys. Brian

I don't even see it reaching out with Wireshark; it would at least try to grab the file (which I'd see in the TFTP logs) and then determine it can't "downgrade" to that version. If it doesn't even try to get the file, how can it determine if it's an upgrade or downgrade? I can TFTP from another device on the network (i.e. if I setup my mac to be on there I can pull down the file, so I know it's not a firewall issue. What is this about port 21? TFTP is 69.

I've tried and tried to downgrade my 2332 from 5.2.0 to 5.1 via tftp. I NEVER see it connect in. I have an International/US camera (Came in white box, not brown). Here's what I've tried: 1) Direct connect to PC host (IP 192.0.0.128) and IPC powered by external adapter (not VM's, physical PC) 2) Direct connect between PC and IPC w/ Crossover cable. 3) Connected PC and IPC to 5 port Switch. TFTP server is Tftpd64 and digicap.dav is in the root dir. I tried pinging and telnetting in to get to the "failsafe" firmware, but no luck. Is there a way to ssh in and get it to boot into failsafe mode? Will it only boot info failsafe mode if a firmware upgrade "failed"? Can I force it to look for new firmware if it's successfully running 5.2.0? I want some of the features of older firmware, thus the downgrade. Is there any way to "trick" it into thinking that the older firmware is actually newer? If I copy the file to the device somehow, can I manually initiate an upgrade? Seems like upgrade binary is only available in failsafe mode TIA Brian
