    Regardless of the fault message (timeout), does your device boot up after the upgrade at all?
    If not, what does UART output tell you?

    Sorry, without UART it's quite hard to say, what's the real problem.
    Did you doublecheck, if you'r tryin to flash the right software? What device, what firmware file r u workin with?

    Provide them all and only those requested will be used.
    For the timeout error - paste a listing of the /root folder here for checking.

    File is normal.
    Try rename it, change tftp template, try it only 1 without run ... but many times, stop your antivirus.

    Yes.
    Dublicate this string several time
    Try rename file and use rename at this script.
    Such a feeling that there is no file or access to it for other reasons.
    Start tftp from another directory, closer to the root of the disk!

    Must be all ok.
    Maybe some disk filesystem problem, check it!

    I'd say, check the 1st post of this thread. With it I was able to unbrick my VTO's a couple of times already.

    ok, I see first step is to connect the VTO to the computer, you have done it over the switch method or connecting to the computer directly ?
    Do you need specific material ?

    I suggest a switch. The timeframe in boot when VTO tries to connect to the tftp server is very short. Via a switch, the ethernet port of the PC hosting the servers is already up when VTO is booting.

    ok guys, i am blocked at the first step where I need to connect the VTO and the computer to the same switch ... have you used the Dahua switch to connect both or an external PoE switch ?

    If I use the Dahua switch, the VTO is powered on, but the computer connected to the same switch is not getting an IP adress it seems.

    If I use a Netgear Prosafe PoE GS108P unmanaged switch, the cmputer is getting an IP adress, but the VTO connected to one of the PoE ports is not powered on (the led on the switch is not on ...)

    Can you please clarify how you did it ?
