Help Dead screen?


I recently flashed a S4 rom for my s3, it was working fine but I went to look for the S4 camera app for the S3. I downloaded it and flashed it using CWM, but when i rebooted my phone after the samsung logo, was just 1 pixed on the top left of the screen.

this is where I got the link from

By the way, i'm NOT rooted.

I've already tried a factory reset and wiped the cache

Right now, i'm downloading the 4.2.2 leaked firmware, going to try flashing that.

Please help :(
