this is a crazy idea but could we do this? :
1) Make an "update eboot" for 1.0.....like not signed by sony obvously...but the same type of file structure.
2) modify FakeUpdater to write to flash instead of ms...this is easy because the source is included.
3) use the 1.0 "update" and write it to flash like an update?
c5cha7 made a while ago a 1.5 firmware that loaded 1.0 eboots using mph/sxt's bfm.
we could put that into a "update" structure and downgrade..sorta...that way?
Let me know what everyone thinks.
If anyone is good at coding and is interested in this let me know.
i have many psp's that i'm willing to brick for this.
