PSP V2.0 to v1.5 Downgrade guide

[hanky]

Unfortunately I upgraded my psp long ago and it seems there’s no turning back for it, but yesterday a coworker lent me his 1.52 PSP and I’ve just successfully downgraded it!! Its kindda scratched and for some reason the analog stick is stuck hitting down (although to physical contact it doesn’t feel weird at all), so Ill try to talk him into selling it to me Thanks a bunch Kaiser !!!

If you downgrade the PSP and then upgrade it will it still think that it is 1.5 or will it change to the new version? And if not is there someway to undo the downgradeing after it has been downgraded?
And btw what is the success rate of downgradeing your PSP (don't want it to get ruined). And what does a bricked PSP mean (kinda new into this download things for PSP ^^)

Upgrading a downgraded psp WILL change it's version. Just upgrade if you want to undo it. And if you follow the instructions perfectly I can assure you you won't break your psp. "Bricked" just means broken. THIS ONLY WILL WORK ON A 2.00 PSP NOT ANYTHING HIGHER.
