Here I will list all of the Downgraders available for your psp. Fully set up for you, so you’s can have confidence on what your doing.

There are downgrader’s out there for the psp, that were beta and have been updated by there creater’s, but some people still host the old ones, which i think are not safe enough to give you’s.

The bad\old ones i have been talking about flash a dump of a 1.5’s firmware onto your psp, so your psp becomes a 1.5, but are very risky.

The one’s i will be hosting flash official Sony 1.5 eboots, so you get a clean install each time , it uses basically the same process that sony uses when you upgrade the psp but in our case the psp is been downgraded.

So I will only give you’s which one’s in my eyes are safe, contradiction sorry the 1.5 to 1.0 downgrader is not very stable but i find the downgrade quite pointless. so you are better off without, but i will just put a link to it, for those you are curious, so be warned. .

All this software has been tested by myself personally. At the start i had one psp and when i finished i still had one psp. Anything that happens while downgrading i cannot be held responsible.
