I got my gdr3 first from preview for developers, then a week after I receive an update from HTC. But then I got issues on the speed of my data internet. So I wanted to reset to its original OS. But Microsoft says once you got gdr3 from preview from developers you cannot go back to its original OS.
So, even I reset my phone there is really no way to go back?
Or is there any???
