R6400v2 firmware corrupted

[andresbarrones]

Hi I have a problem with my R6400v2 router. I tried to install the TomatoFirmware firmware but it seems that there has been a failure in the installation and the system has been corrupted.
The router does not stop restarting, I leave you a video for you to see. Any advice on what to do or how I can solve this error.
I have already reset the factory with the back button but nothing keeps doing the same.

You can try recoving it with tftp or nmrpflash.  

are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.

and if that doesn't work, you can try using nmrpflash

If that doesn't work, check on the tomato forums as they'll be more familar with undoing what their firmware did.

It doesn't exist and there has never existed Tomato software for R6400v2. Sorry.

ok but do you have any idea how to repair the device?
