http://forum.xda-developers.com – I rooted with locked bootloader, and then supercharged. I could not get 100% charge level because I needed to mod framework.jar, which I can't do (and won't bother to learn). Anyway, I noticed that if you supercharge to 50% the home will get noticeably laggier for some reason. So yeah, don't supercharge to 50%. (HowTos)
