It was working normally after the update and for one day the screen wasn't working but it was connected on the phone and then it died after that day. We couldn't charge it all. (It's my girlfriend's) She says it might be the sea water that damaged it, but I doubt
I have a similar issue. After updating into new firmware the band didn't charge. Now the battery drained out and it doesn't work at all. Any ideas to see if the band actually works? Is there a way to connect it to PC via USB?
