Two days ago suddenly my instinct solar becomes out of control.
I am not at the country where the purchase mine.
So, I struggled to fix it at least morning run activity... Still pulse ox is not available(turn on for sleep monitering then critical error comes)
Hard reset is not working, soft reset not working, just all the time automatically switched off problems.... downgrade software version is not possible. just not working..
Oh, I found the solution yesterday.
I am sure who has a same problem with me, It will work....
Solution > download "InstinctSolar_1691beta" unzip > copy "SensorHub_1800 folder's GUP3467.GCD" to Garmin watch. > install
- Connect the watch to your computer.
- Unzip and copy the included gupdate.gcd file to the Garmin folder on your watch.
- Disconnect the watch from the computer and it will prompt you to update software.
It works fine. I am waiting for morning run now.... it is raining but I can use garmin now. already tested 15 times... never switched off...
Never forget, trun off automatic update in setting on garmin watch. It will automatically update to new verson of firm then start problem again.
Hope your exercise is okey.
