downgrading 3.03 to 1.5 ? Is it real???

[HANZO]

Hello PSP owners!!!

Hey! I just find this info about downgrading 3.03 to 1.5 and I will like to hear some opinions; I don’t know if is a breaker, so you better be careful if you are going to try it, but if you do let me know if it works!!!

This is the link

Yes it's real... I even wrote a tutorial on it:
[Tutorial] Downgrading a v3.03 PSP to v1.50/v3.03 OE

100% Real.
Thanks to the brilliant guys of the Noobz team, the same guys tho brought us the many versions of Eloader (a way of loading homebrew on firmwares that couldn't be downgraded at that time).

Edit: You can download the files form the site you linked to, or use the links in Evolve's guide (links are from qj.net, a trusted source) if you want to be extra sure.

I have downgraded from 3.03 to 1.50. But do it at your own risk, Also browse some forums and see other people experience doing this

I'm about to downgrade in a week or so.
