This thing abit misleading then & worked half way:

When my Silver at 3.03 OE-C, I tried this tool. It fixed my XMB 1-2-3-4 but in Homebrew still stuck 3-2-1-off. If I change the level within homebrew, when back to XMB it screwed. Then I used IdStorage & delete my key 8. And then I decided to upgrade straight to 3.52 M33 then M33-4, but the brightness didnt fixed. Im confused. So did key 8 related to brightness but u said nothing to do with keys. +___+;
