I've been having a few problems with my psp lately. Anything that uses wifi freezes the psp as soon as i try and load it, and a few other random glitches. This all started happening after i put on my custom icons. I tried putting the default icons back on but that hasn't seemed to have helped. Is it safe to run the sony official 1.50 update from the recovery menu then do a clean update to 3.40 oe? I ask this because i read on DA's website somewhere that if i downgrade to 1.50 from 3.03 official, upgrade to 3.40 oe, then down to 1.50 then back to 3.40 oe it will brick the psp, something to do with 3.03 hen.

Is it safe?:S
