so I was trying to download the new GTA SA by spoofing my phone as a GS4 because google is a piece of shit. I downloaded a app called "Device Spoofer" selected my phone as a GS4 and it rebooted. Now won't boot past the boot screen shows android and thats it. Did a MD5 check says different from stock so I'm assuming this stupid piece of shit app screwed with the image and tried to boot as a S4. Now I'm kinda mcf%cked. Someone please tell me how to flash the stock MD5 on this phone with a step by step PLEASE!!!!
