thanks, but unfortunately, as long as ActiveSync is down on the PDA, nothing can be done to perform an extra upgrade or anything like that. Even hard resets don't work.
The problem is that ActiveSync needs a sort of "client" software running on the PDA. If it doesn't work, communication between the computer and the Axim is not possible. Thus making impossible any other update.
It seems quite nothing, this small app on the Axim (btw, the exe is in the Windows folder, and is repllog.exe -- in case this could help anyone). But it is just like trying to put a key in a keyhole filled with hard concrete...
