Here's a complete guide to what preloader does and doesn't do.
PRELOADER HAS NEVER BRICKED ANYONE. IF YOU THINK YOU ARE BRICKED, BOOT HBC AND REINSTALL PRELOADER.
Nope, it hasn't. If you get the "System Files are corrupted" message, just reinstall preloader. Away it goes!
PRELOADER CAN BE UNINSTALLED EASILY.
Just re-install the system menu, which also won't brick you. You can just use WAD Manager and a System Menu WAD from NUS Downloader, or use Waninkoko's Firmware Downgrader.
PRELOADER DOES NOT LEAVE TRACES.
Just re-install the system menu, and away it goes. Not hard to remove.
PRELOADER CAN RECOVER FROM WAY MORE BRICKS THAN STARFALL CAN.
Banner bricks, bad theme bricks, bad region bricks, and many more. All without a GC controller and/or having to have the TW Hack in NAND.
PRELOADER WORKS ON 4.0 FOR BRICK RECOVERY.
Starfall doesnt, and is outdated. StartPatch does, but again, it needs TW Hack in NAND to work, and 4.0 blocks that.
So, in conclusion, there's no reason not to use it. Make sense?
