here is a better 1.5 file
http://www.psp-hacks.com/file/4

for ur 2.0, u can downgrade from 2.71 or 2.80 downgraders (recommend). These is also 3.03 and 3.50 downgrades but ill less recommend this one

for ur 3.50, u need pandora's battery. To get this, downgrade ur 2.0 psp to 1.5. Then upgrade to a custom fimware. After use this guide

i think u should upgrade to 3.90 M33 (do u need a guide to upgrade?). Installing custom firmware is really easy so there is little change of bricking. Even, if u do, it still can be fixed

here is a guide to upgrade ur firmware
http://forums.afterdawn.com/thread_view.cfm/616311

I rather recommend using the 3.50 downgrader, if it bricks or dosent work then use my guide. Pandora battery can fix brick psp

Here is a guide for 3.50 downgrading, make sure u got the unpatch lumines
