Hello everyone! I've searched all over the place and I could not find an answer, so I came here hoping to find one. So, my problem is: I have a Sprint Samsung Galaxy S4. My friend talked me into rooting it, so I did. I installed Cyanogenmod along with it to get the stock android os. Well, I'm really regretting it. Could anyone tell me how to reinstall my Sprint Galaxy S4 stock firmware, as well as unroot, AND reset the binary counter? Thank you in advance!
