    Bricked my NVR by updating from very old firmware straight to latest one.

    That looks perfect - well done! I generally use the web interface as the most common reason I have for reviewing playback is to see events on an NVR that is configured for event-only recording. I have 2 NVRs connected to the same cameras, the other one is configured for continuous recording...

    Confession: Crossover Cable

    No big deal - TX-, TX+ That will not cause damage either.

    DS-2CD2135 firmware upgrade

    Yes, I'd guess it has the 'Dieter & Fiona' hacked to English firmware that if upgraded would stop the device working.

    Xmeye NVR DVR Board

    They sell loads of different models - without knowing which one, I doubt there is much help that can be offered to you. What details can you provide? Including the camera types and specs.

    "Time out" Activation camera

    Yes, they are. Dumb question - but presumably all you attempted was to provide a strong password, applied in SADP?

    Amcrest Smart Home (ASH), No http web user Interface, Boooo!

    Because they have designed it to be simply operated with their proprietary Android or IOS app. This is never done from scratch, lots of ready-made solutions that just need a little customisation to work for the specific device.

    That's an interesting question. Looking at the Prolific specs, it doesn't mention the signal levels, looking around elsewhere suggests the TX is 3.3v which matches the NVR requirements. There is a 5v VCC available on the device, but that's not needed and should not be connected.

    Bricked my NVR by updating from very old firmware straight to latest one.

    From what I recall (it's ages since I bought any of these) the TA version is required if the PC is running Windows 10. A driver issue. You'll notice that compatibility isn't mentioned on the non-TA version. Also - it's easy enough to insert the connector wires into the -TA version adaptor...

    Bricked my NVR by updating from very old firmware straight to latest one.

    That's the NVR probe looking for 'Arecontvision' devices that it puts out on normal bootup. It uses a similar handshake to the Hikvision tftp updater - so the tftp updater comments on it. It's not an error, but it does indicate that the tftp updater handshake has not taken place and the NVR has...

    Wow! Well done, a great result. Thanks for sharing.

    Vanderbilt NVR without password.

    You don't need Linux to pull the copy of the mtdblock1 - just the serial TTL to USB convertor, a serial terminal program (such as PuTTY) and the tftp server. So if you do manage the dump, and don't have Linux for the actual extract, you could attach the file here and I can check it out for you...

    Vanderbilt NVR without password.

    That depends on whether you are feeling adventurous! It's quite an old, low-level NVR. A couple of ways to deal with the password - Apply the Hikvision firmware with Hikvision's tftp updater. If it takes - the device will be reset. or Extract a flash partition and decode the contents, like so...
