I have had quite a number of reboots on the latests FW (9.73). Some of them not too bad, where it reboots and comes up in an almost "ride paused" state and I can resume. However, yesterday it rebooted in such a way that the entire ride up to that point was lost and I could only record the last 20k's post-reboot.
A couple of days ago I had 2 reboots in the first 30 min of the ride. Fortunately nothing on my long ride Monday - otherwise I may have tossed this thing down the mountainside! ;)
None of the rides were with navigation - I just rode and recorded.
Is there a way to revert to the last (previous) stable version?
