So my watch to was stupid k in reboot loop so I tried with the power off holding the power/home botton waiting for the Samsung gear prompt came on and while still holding after it went off then still held while it ran through the Samsung gear S3 reboot prompt came on and disappeared and and came on and went off and came on and went off not letting go until about the 5th Samsung gear s3 reboot prompt showed and then completely let go and within a matter of 10/secoond not only was my watch fixed but I lost absolutely no data still had all my apps and watch faces everything was still there... So hopefully this helps you and others just like it helped me good luck
