I recently updated to v4.2.1 a month ago. I have had a few bugs since then. Sound quality from helmet to helmet is a lot better though..
This past weekend, I shut it off while stopping for lunch to save battery. After lunch, it wouldn't turn back on. I did a firmware restore when I got home. Seemed to work fine.
I was advised anytime after doing a firmware update, I should do a factory reset. So I did and it and it sent my SMH10 back to v4.1.1 Kinda went backwards. Is that what is recommended? Did I do something wrong?
