Please help! My phone is a Samsung Galaxy S3 AT&T (NOTE THAT I AM A NOOB AT ANDROID AND HARDLY KNOW WHAT ANYTHING MEANS!) I installed CyanogenMod11 on my phone and now I want to delete it and get my phone back to stock because my Mobile Data is not working! I have tried flashing stock back on with Odin but I kept getting a fail! This is my first phone and I installed CM11 because I thought it would be cool, my parents would kill me if they found out that I kind of messed up my phone! Is there an easy, fast, noob-friendly way to get CM11 off my phone? Please help me, I am very frustrated because I am normally good at tech stuff but Android is hard stuff and I really want a painless, easy way to unroot/ delete CM11 off my phone and get back to stock with everything back to normal!
