How did you try reinstalling? Use a .ftf with Androxyde's Flashtool, provided you're able to boot into flashmode (if you can't, sorry bro, you're screwed). Flash everything, but uncheck DATA in the Wipe section if you want to keep your files - you'll lose them otherwise (your apps are gone anyway). This should work, as I've bugged, bricked, and bootlooped my phone more times than I can count, and this has always worked. If it doesn't, then I don't think anything can help you.
