Unfortunately, it is not possible to see the Connect IQ related changes from 3.0.7 to 3.20 :confused: only from 2.70 to 3.20.
Lo mismo me pasó a mí Fernando. Cómo podemos hacer downgrade?
If you want to downgrade, you can download the software for 3.07 Beta and use the 2.70 update file found in the zip. I have not found any specific 2.70 download pages...
Once you have the rgn file, simply copy it to the Garmin folder of the watch and disconnect from USB...
It worked for me, but there are no security here....
