Ответ на "strap broke and unit will not communicate with app"Call FitBit. They will check to see if it is still within warranty. Even if it isn't, they may offer you a discount on a new FitBit. That's how I got my Charge 2.
Ответ на "iPhone could not be restored unknown error 1"I have run into this when the backup I was trying to restore from was from a phone with a newer version of iOS than what was running on the phone I was restoring to. Try setting it up as a new phone first, then update iOS to the latest version. Once the phone has been updated, you should then be able to restore it from the backup.
