I ask the same question. And theoretcally, I'd say the answer is probably yes, if you could get someone to give you their 1.00 firmware dump.

He says it only works if the 1.0 dump is from your psp not someone elses?

Absolutely, the nand dump you get with his "Backup" tool can ONLY BE FLASHED BACK ON THE PSP IT WAS DUMPED FROM using his "Restore" tool. Therefore a 1.00 Nand dump won't do a 1.50 owner any good since the flash WILL DESTROY HIS PSP. Got it?
Later,

TSR

It all depends on how the flash is dumped.

a 1.0 downgrade may be possable if you use part of your 1.5 flash and alow it to restore it

Man I always wanted to step back and take my PSP to its roots and go to the JAP PSP's. It is truely a dream of mine. Even if apparently not all homebrew any more works as good as 1.5 firmware. But I don't care 1.0 firmware is the way to go!

so a person with a 1.0 can back it up upgrade to 2.0 then downgrade to 1.5 then go back to 1.0?
