Changelog for v1.04

- Added some fixes to the PUP to eliminate many "Data Corrupted" messages from different installation methods.
- Updated the PlayStation Home Fix Package to v1.04, Now PS Home Icon will be installed to the TV/Video Category.
if i'm on the 4.30 rogero 1.0 i can upgrade directly on 4.30 1.04 or i need everytime first downgrade to 3.55?
You can just install the v1.04 firmware (v4.30) straight from v1.00, but you're better off downgrading first with the downgrader PUP then installing it from KMEAW in recovery mode once you have installed both the Rogero v3.7 (3.55) and KMEAW via recovery mode.
