In the last days my FR230 crashed twice: the first time the battery was around 30% and laps were set automatically (1km), while the second time battery was around 60% and laps were manual. All crashes occurred after the lap time was displayed on the watch: the watch just turned off. Other people encountered a similar issues after upgrading to SW version 7.50. I tried to install the beta version 7.52 by following instructions given in Garmin's web site, but the watch ignores the update, any ideas?
I was also wondering whether it is possible to downgrade to SW version 7.4.
