The Noobz crew posted this news:
After some exhaustive testing, we've now come to the conclusion that there is no unnecessary wastage of flash space during the 3.03 downgrader process.
This means that our belief that there would be a need for a "flash cleaning" application was wrong - you should be able to upgrade and downgrade your PSP at will, with no serious problems except for the ever-present small risk from any downgrader.
Our original theory was based upon the fact that Fanjita's Undiluted Platinum test PSP showed signs of having run out of space on the flash, after several cycles of upgrade and downgrade.
The symptom, for reference, was an error code of "8001001C when starting ipl_update.prx" - which means "no space left on device" - when trying to run the 3.03 downgrader.
But after an extensive test of 10 upgrade/downgrade cycles between v3.03 and v1.50 without any problems, we believe we can now put the problem down to issues with the interaction between the Undiluted Platinum flasher program, and v3.00+ firmwares, which has previously caused flash problems with other people's UP PSPs.
So ... no worries!
