Yes, This is what a bricked PSP with a bad flash does. This problem is what this project was originally targeted at. It's a happy coincidence that this will also work as a downgrader.

As to questions regarding the "stripped-down 1.5 firmware", If you want to keep a full 1.5 firmware, just upgrade to 2.71 and then downgrade to a full 1.5.

If you want to run a CFW, then either use the method above to get a full 1.5 install to upgrade or you can probably just install the CFW on top of the stripped 1.5, just as you are doing with any firmware upgrade.

Disclaimer: I've yet to actually test this myself, as I am still at work (I will be doing a ton of testing when I get home...) I am basing these suggestions on previous posts. (PLEASE READ THE WHOLE THREAD!!!) Sorry, didn't really mean to go off there...

Just reading the thread and using a little thought will answer most of the posted questions.

And as to the 32MB card questions: Which is more expensive, a 256MB Pro Duo card or a new PSP?

And yes, when you're through unbricking your PSP, just reformat it to use with your saves.

I'll shut up now...

Not sure...but it would be nice to figure out...If I can indeed restore my brick, despite the flash0 being totally gone, that'd be great.

if thats the case then it does not matter cuz i can get a new battery and thats it. cuz some ppl are saying that u need it to be intact in order to downgrade

Is this some elaborate trolling opration? I just gave you 4/10 on your mininova torrent, but after seeing this chaos I can say you deserve much more than that. Even GNAA would be proud.

There's no way to read/write data on battery. Don't run executables if you value your psp.
