Why should I do this. Got mine running already with all the homebrew but without the browser (only trough DH).
Mine 2.71SE/3.00 is running quit stable and is also modded with font, gameboot and some other stuff of x-flash(wave gone, black background, psp brand removed, etc etc) (that is working fine under this version).
It also looks that everything can be booted from the recovery menu or from the autoboot.
I will stick to this for as long there is no stable installer or a version with the browser working.
I'm going to make a tut how I did it maybe, but I think it's best for most people to wait longer for the good dev's to make a installer or even 3.00SE-A.
