Dont know what you did wrong but it worked for me. I uninstalled the one that was on there and now I using S-Health again..... Another one to use is Microsoft Health.
I just flashed it and it's working a charm. It kept looping after it said it restored my old data (there was no old data). I cleared the app data and cache and force-closed it. Upon relaunch it loaded properly and is working now.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
