Dark Alex has released a new downgrader for the PSP, heres the release details:
This downgrader lets a psp running firmware 2.71 and HEN C to downgrade to any version from 1.50-2.60, or even reflash the 2.71 version.
This downgrader is safer, faster, and a lot easier to use than the previous downgraders. It also makes a clean firmware install, since this time there is a format of flash0 (just like sce updaters do).
A firmware dump is not needed, only the eboot.pbp of an update.
Ta-082 users can downgrade to 2.70/2.60/2.50. TA-082 users, DO NOT downgrade below 2.50.
