Hey, well done!After doing the downgrade to V5.2.5 and doing the "enhanced mtd hack" I was able to update the firmware in steps from V5.3.0 to V5.4.5 thru the GUI.
Interesting.I thought I had read that they could be 02.
There is another user that is seeing the same symptoms as you have described, I'll point him to this post.Not sure if this caught anyone else out but if it did, make sure you change 00 to 01 in MTDBLOCK1 file
There is an EN version and a CN version of the downgrader. Which did you try?I tried with the downgrader 5.3 -> 5.2.5 but it failed. TFTP says transmit
It is possible to modify mtdblock6 hardware signature block on newer firmware - but it looks like Hikvision have created a trap for that activity, possibly to catch those that have done the 'mtd hack' to convert to English.You have use downgrade firmware 5.2.5 En (on other thread) with tftp ?
I've not seen any firmware later than 5.4.5 yet for R0 cameras.Has anyone tried to upgrade later than 5.4.5 with the mtd mods?
That sounds like 5.2.0 or older firmware was on it. I don't think that will be a problem - if the new firmware finds this block erased like that, it creates a new template and keeps goiing.My DS-2CD2532F-IWS has the mtdblock1 empty (full FF).
So far, with loads of devices, I've seen none that also need mtdblock5 changed.Should I change something in the mtdblock5 with that model or is changing mtd6 enough?
I would not be surprised - unless they want to break a few things for spite.So it seems that the 5.4.5 might be the last fw for the R0 models.
I just wanted to say thanks for posting all this! I have some DS-2CD2532F-IS cameras that had been getting randomly (or so I thought) factory reset. I found a thread on that topic which led me here, and with the instructions in your files I was able to get all my (Chinese hacked) cameras updated cleanly from 5.2.5 to 5.4.5 without any issues (plus fixing my router security settings, changed all the passwords, etc.).I was not going to post these details in public, to reduce the chance of Hikvision blocking them in future firmware - though no such inhibitions in private, quite busy on the topic!
Well done, yet another good result!Just updated the first one of my two 2CD-2132F with 5.2.5 firmware that showed random factory reset.
That's the case if the camera originally had very early firmware, such as 5.2.0 as far as I recall.I've found that the mtdblock1 was filled with FF, so I was a bit scared to go ahead, but everything's went fine.
Even better - excellent!Also set up a VPN server with Raspberry Pi... no more open ports...
There must be so much of this going on around the world.5.2.5 firmware that showed random factory reset.
