So here's what I did: I wanted to clear some space and start from scratch on my S3 (d2usc), so I wiped and used odin to go back to the stock 4.1 firmware. I updated OTA to 4.3 then I flashed CWM touch. From recovery I flashed SuperSU and the most recent CM11 nightly along with gapps. It was running perfect at this point. I made a backup and that's when I decided I was pro enough to flash a custom kernel in recovery. Specifically this one. Which I'm sure is a nice kernel, if only it was made for my device *facepalm* So now it won't turn on. No download mode or recovery. When I plug in to my PC Windows doesn't recognize it. I can hear the "plugged in" sound, but it sounds sort of laggy. When I unplug it I get the normal "unplugged" sound, but the screen stays black no matter what. I also get a red LED when plugged in without a battery. I'm thinking my only option might be a USB jig, but I really have no idea if that will work in this situation. So what do you guys think? Is it salvageable?
