I have a problem with my Netger R6400v2 router. By mistake I've uploaded the firmware for the v1. I've tried to upload the correct v2 firmware via TFTP (using tftp2.exe, tftpd64 and Windows 10 commands) but no results. Also tried to upload via GUI but no effects. Is there anything I can do to repair my v2 router? Or maybe sameone try to explain me step-by-step how to upload the right firmware using TFTP? I must say that the v2 with v1 firmware works quite good (I'm actually surprised about that) but half of the options are bugged and doesnt work propertly.

What does the router do now? LED indicators? Any network communication?

"tried" or "no results" is not a useful problem description. It does not say what you did. It does not say what happened when you did it. As usual, showing actual actions with their actual results (error messages, LED indicators, ...) can be more helpful than vague descriptions or interpretations.

"tried"? "no effects" Does the router's management web site ("GUI") work at all? See "not a useful problem description", above.

Where's your "step-by-step" description of what you did, and what happened when you did it?

What, exactly, happens when you try to load the right firmware using the normal (ADVANCED > Administration > Router Update : Locate and select the upgrade file on your hard disk)?
If that fails, then I'd try the TFTP recovery scheme, but if that fails, then a better problem description than "no results" would be needed to try to understand why.
1. The router act normal (all of the LED are white). I can connect with the internet and use it (with cable and via Wi-Fi).
2. In tftp2.exe I recieved "Unable to get responses from server." message; In tftpd64 when I click "PUT" button, "block#0" appeared but nothing happend; In Windows cmd tftp i recieved "Connect request failed" message. Each time I turn off and on the router (with reset button holding at the back) before I proceed with the upload the firmware. (I bind the IP adress too). After that the router boot normal and is usable but still with the v1 firmware.
3. I can get acces to GUI via web browser. It looks like the one from the v2 firmware but there is caption said its R6400 (not R6400v2). When I try to upload from my hard drive the v2 firmware through "Router update" after a few seconds the GUI respond with that message: "This firmware file is incorrect! Please get the firmware file again and make sure it is the correct firmware for this product.".
To sum up: my router works normal, I can connect with ethernet cable and Wi-Fi. I've tried three different tftp methods, all of them fail.
I think the tftp might help but I dont understand when I have to proceed with the upload during restart.
I'd forget the fancy third-party programs, and stick to the built-in, simple, command-line TFTP client program. In any case, you need to configure the network interface on your computer with a static IP address (et c.), which steps you haven't mentioned.

Not a very detailed description of anything.

If the firmware is too smart to let you load firmware for a different model, then the TFTP scheme may be your best bet.

Do you ever see the Power LED flashing as it says in those KB articles?
What happens if you ignore the Reset button when you start the thing?

Whenever it works? Some experimentation may be needed.
Just one thing to add that has not come up already, there is a more thorough "recovery reset" that you could try:
Press reset for 30 seconds
Keep pressing reset while removing power
Keep pressing reset for another 30 seconds while apply power
This is something that Netgear sometimes requires when people are doing fancy stuff in beta tests.
I am surprised that you managed to force the wrong firmware on to the device. The process usually fails because the update process is smart enough to spot the mismatch. Are you sure that it took? After all, your router is still working.
