i just started using cfw on my psp. i currently have a GoW slim with the TA-085 mobo using 4.01m33-2. it's been awesome so far but irshell doesn't work very well. i can see how powerfully a fully functional irshell could be, so i was considering downgrading the cfw. my only problem is i don't have a pandora battery. the one i hardmoded to get cfw 4.01m33-2 installed, just died on me. anywho, i'll give this homebrew a shot. it will be awesome if i can downgrade without a pandora battery. all the research i did mentioned that i needed a pandora battery to downgrade, so this is kind of a big deal for me. ^^
