    Hikvision 5.2.5 & 5.2.8 Full English (INC DAYS OF WEEK) mtd Hack

    Nevermind... Sorry about the wasted space. I just noticed several posts from this thread where @whoslooking mentions that my symptoms describes one of the newer 5.2.x cameras and that "most version of manufacturing dates 2015/01 won't work with anything less than 5.2.5". I guess this just...

    Hikvision 5.2.5 & 5.2.8 Full English (INC DAYS OF WEEK) mtd Hack

    Figured I'd post my results after trying to perform the mtd hack on one of these cameras. First of all, I realized that my comment about the version differences reported by prtHardInfo and the web interface was incorrect - the particular camera I was working with had FW 5.2.3 installed, and was...

    Hikvision 5.2.5 & 5.2.8 Full English (INC DAYS OF WEEK) mtd Hack

    OK, so I just pulled the mtdblock5 and mtdblock6 off the first camera. Strange thing is, when I ran prtHardInfo, the terminal responds with version 5.2.3, but the web interface reads 5.2.5. Either way, I had no issues with pulling the mtdblocks off, but I figured that I'd take a look at the...

    Hikvision 5.2.5 & 5.2.8 Full English (INC DAYS OF WEEK) mtd Hack

    Is there a general consensus at this point as to which bytes are OK or "best" to modify in order to "balance the checksum"? I noticed that @whoslooking preferred modifying the MAC or Reset codes: But I would prefer not to play with my MAC address, and for that matter the reset code. I also...
