Hello guys! I'm all new to this custom rom thing. So I was running stock 4.3 android on by T-Mobile S3. I saw online that Cyanogenmod is much snappier than Touchwiz, so I downloaded Cyanogenmod Installer and follow the steps. After it finished, it goes past the Samsung Boot screen for like a second and then I get stuck on the Samsung Galaxy S3 screen... Help! I can't use my phone now.
