For reference - my old Chinese DS-2CD3332-I which arrived with hacked english on it was also happy with the devtype 0898 - DS-2CD2332-I Mark

Just to confirm. Changing byte 0x55 from 1 to 3 and rewriting back to the camera has indeed now given me a serial number of "DS-2CD2332-I20150415CCWR5...." rather than CCCH and the US English 5.4.5 firmware is happy on it. Thanks

You appear to be running a newer build of busybox there. The one I have from the brick_fixv2.zip is; BusyBox v1.19.3 (2014-03-28 16:33:55 CST) Which doesn't appear to have printf in it. It's also objecting to some of the read command. Looking at the tools in that build it's probably...

I'll see if I simplify the maths down. The for loop should be easy but the printf's may be a different issue. So on the firmware side: If we want to get it out of China region 5.2.5 is the last working firmware? Also if, like me, we've upgraded to 5.4.5 that'll probably explode if we do any...

All worked fine. Managed to mod the DS-2CD2332-I using devType 08 98 and then directly to v5.4.5 (US English) from; https://us.hikvision.com/sites/default/files/firmware/ipc_2xx2_en_std_5.4.5_170123.zip Serial still has reference to CCCH serial. Device details attached for reference. Thanks...

So now that I've worked out what hikvisions checksum is actually doing here's a, rather wordy, linux script to calc the checksum https%3A/github.com/darkorigins/hikvision/blob/master/scripts/mtd_checksum.sh']https://github.com/darkorigins/hikvision/blob/master/scripts/mtd_checksum.sh $...

Hi ... so I've submitted and installed a virtual windows machine with HxD on it ... well didn't have much else to do overnight :) Checksum Location bytes 0x04 -> 0x05 Checksummed Offset 0x9 Checksummed Range 0x09 -> 0xFC Checksummed Length 0xF4 One thing which caught me is...

Hi Replacement for the TFTP hikvision tool was standard tftp server (to send brickfixv2CN.dav) + little python script that responds to the hikvision handshake on udp 9978 epol/script Not sure how the fixup_stage1.txt file vanished previously ... seems to be ok on a re-run. Exact details below...

Hi All, Just working my way through your amazing work, having upgraded the wrong camera and bricked my Chinese 2CD2332-I :-( The world is slightly complicated because I have no windows machine here (lots of mac/linux ... but no Microsoft unless I install a virtual machine up) So one...
