I have a psp which has a custom firmware installed. I recently updated it from 3.70 to 3.90 using dark alex. Now, I wanted to downgrade it to 3.5. Is that possible? Would it not brick my psp?

*NOTE* I can change to 1.5 in my firmware (XMB)

y'd you want to go back down?

you'll have to use upms or the very first pandoras battery to downgrade all the way back to 1.50 and then update to 3.51m33
