I just recently got a Galaxy Fit (SM-R370NZKAXAR). It was one sale. I charged it, downloaded the wearables app, and paired it. There was a notice about to update the band software. I downloaded it and attempted to install it. The installation failed and the app said to try again later; while the Fit simply had an exclamation point (!) on the screen and would do nothing.
I have tried updating the software more than a dozen times, with the same result. Sometimes the progress "clock" gets to around 20%, sometimes 80%. The highest was over 90%.
I have reset the Fit several times and re-paired it; but, it has made no difference.
I have uninstalled the wearable app from my phone and re-installed it; but, it has made no difference.
Now, I cannot even use it without the update, as after a reset, once it's paired with my phone, I get the exclamation point.
Any ideas, ohter than using it as a light-weight paperweight?
