Start file transmittingįile size limit sounds viable, have read others suggest that, but surely that would impact everyone trying to do it? (all firmware look the same size except for. Have tried a few of those files before, but again now V3.4.82, V3.4.98, V4.1.10 and V4.1.60Īll had the same result - retry after ~2m7s (and I've left that run for 26mins/9 retries on one TFTP attempt) Think the only official option is hikvision tech support for GUID code/key/file, but not sure if they'll play ball with a second hand unit? (could ask I guess, but don't want them to blacklist it) Using the monitor I can't find the hidden button in the lower left (V3.3+ stopped that?). I can also hit the GUI via 192.0.0.64 but don't have login credentials (need to reset it), and not sure of default. I can see the GUI on the monitor, but the usernames to select from are all strange characters, with 4.0 in top left (was told database corrupted) I've ordered a serial cable (no rear DB9 to connect to, so I assume one of the 4pin white plugs on the mainboard required?) It doesn't seem to complete the transmission. PC has the 192.0.0.128, and I only have the NVR connecting from 192.0.0.64 on the same LAN segment (nothing wireless). etc (for 20 mins, up to 9 repeats and counting) I've set up a TFTP server, and can get it to connect and start the download, but it just seems to repeat: Little unsure what firmware to use, but some google posts suggest the NI can be upgraded with EU firmware? I've tried a couple different ones, but run in to the same issue. Hikvision says that firmware upgrades must be. This is method that helps TFTP to achieves flow control. It's a region RR, currently can boot up to GUI showing v4.0 of whatever firmware was on there. HikVision USA FTP Firmware Listing DS-2CD6412FWD-C2 I found that downgrading to V5.1.7 140904 works fine, re-installing V5.3.0 build 150513 is good but upgrading to V5.3.6 151031 or v5.3.6 160218 mid FW in any sequence always bricks the camera. 0 Comments TFTP, Trivial File Transfer protocol, is a file transfer protocol is used for transferring small files using UDP across networks, preferably LAN’s, as UDP is a connection-less protocol with no confirmation of packets received/sent. I recently received an NVR with corrupted database (likely installing incorrect firmware), and want to put fresh firmware on it and try to bring it back to life. Hi all, hoping someone may be able to help please.
