Netgear 3700V2 - Cannot connect in failsafe after upgrade

[diskers]

Hi everyone,
So I upgraded to 1.57 without retrieving previous config. After the first reboot Iogged using webpanel changed the password and rebooted. Aftre that i wasn't able to get to the webpanel, after many attempts I tried to connect using telnet but I can enter in failsafe mode but cannot ping the router, so i consequence connect using console. Anyway I think that the device in bricked

Your device is not bricked.

You may have to access it via serial console

See that for details

Failsafe mode should always work though

Have you tried following this?

Make sure you do failsafe with no ethernet connected, then
once it looks like its in failsafe mode, then plug in the ethernet cable

Hi again,
I don't know why and how but few days ago after getting a wndr 3800 for a good price, I powered again the wndr 3700 v2 and was unable to connect again to the console. After two or three restarts finally I was able to connect to the console using putty and to make a firstboot. Now the router is working fine
