Hey guys!

I just got my 411S for Christmas and attempted to upgrade the f/w to FS0H via the EXE file. Simply opened the ZIP and double clicked on the exe file. The rest is a nightmare. However, when I upgraded, I was using FS07. Whats the rule of thumb for upgrading f/w when you go from a really old version to a new one?

There are no special instructions for “really old” firmware.
If it doesn’t work check out some of the other flashing methods found in the guide in my signature.
