I was wondering if anyone could give me(noob) a quick tutorial on how to use Odin multi downloader to flash kernels. I've been wanting to flash Unhelpfuls kernel, but id rather not brick my phone lol. I was also wondering if anyone could tell me how to get the lag fix for my phone. Iv already rooted with unleash the beast, so i wasnt sure if it was possible unless i flashed to the stock rom and used SuperRooter...any help would be much appreciated
