question about old cfw

[scarph]

i think my friend has hen on his psp
i put it there a long time ago.

no matter what i do if i hit network update, will his psp turn out fine?

his dad wants me to put it back to normal

even if there was a crazy cfw

would it just go to 3.52 and be normal

If you don't have CFW on it (HEN doesn't count) then it will work perfectly.
If you DO have CFW on it you need to go to 1.50 first, then update as normal.
