Some people are wary that the use of downgraders will leave their systems essentially useless, or "bricked" as they say. The process isn't the simplest to follow, and copying over system files is always a dangerous thing. However, the homebrew team at N00bz have created the "safest" downgrader yet. It has built-in security checks, support for TA-082 and TA-086 motherboards, and includes most every file you'll need to revert your 2.80 PSP down to PSP 1.50.This doesn't mean that it's 100% fool-proof, as the warning attached to the downgrader states. However, there's also a new alternative: by downloading and installing HEN-D to a PSP version 2.80, you'll be able to launch a good deal of homebrew without having to downgrade at all.
