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.

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!

Thanks Noobz for this good news/info. This is the answer I'm looking for in my post regarding the downdater. So, it is safe to upgrade again to 3.03 and redo the downdate for familiarization purposes - practice makes perfect... Hehe... Great work guys and keep it coming!

That's good news - I have a friend who is terrified of the process, so now I can demonstrate how (relatively) safe it is by reversing the process a couple of times on a demo PSP. Homebrew capable PSPs; time to multiply!

As a responce to those asking about downgrading from 3.03 to 1.50 and back to 3.03 and then back down to 1.50. I personally attempted this on a friends PSP and had no problems. The reasons for this was, getting a "game could not be started" error so I thought we may have missed a step (no brick thank god). Thanks again Noobz team! You guys are great!
