I would love to try this particular method, except Monkey will not recognize my HD500x. For some reason, when the servers are disconnected, it will only recognize devices that have been recognized during a previous load (when the network was able to connect). So, I cannot even offline flash my firmware. :( Hopefully they get this server back up soon. I've even tried using VPN's , hoping that an EU or JPN line6 server would connect...no dice.
I know it's happened in the past... and it seems to have happened again. My line 6 Monkey cannot connect to Line 6 Servers. I tried the three older methods of "fixing" the problem by uninstalling/reinstalling (including a registry clean). I also tried to deleting content of the app data folder (windows 7), as well downgrading to various older versions of Monkey. No joy. I'd really like to flash my new HD500x with the latest firmware... any help?
