I am having a similar problem today, actually. For my first dive in two years, I charged up the i330R last night and connected it to the DiverLog+ app, which asked me to update the firmware. It seemed to successfully update the firmware to version 2.022.
Did my first dive today just fine. During surface interval I even uploaded the dive data.
During the second dive, the screen went dark, and when I got back I see that it is flashing FW Error Please Reload.
DiverLog+ won't connect to it now, at least not to sync. It does seem to recognize that the DC is there, but no more than that.
I've sent a note to AquaLung, but don't have a lot of hope for that.
Any of you have any suggestions? I'm down here in Cozumel now and diving the rest of the week, so I'll need it.
Thanks for any suggestions at all.
