Tommy1994! has posted about a 3.71M33 to 1.50 downgrade procedure on the QJ.NET PSP Development Forums. The cool thing about this downgrade procedure is that it works even without using 25 Comments

Because the Slim's hardware was purposely altered so that it is incompatible with 1.5. The Slim can NEVER be downgraded to 1.5.

I'd actually buy a slim if it could run 1.5fw or kernel mode homebrew.
Until then, IT'S CRAP!

Yes, I was hoping (and assuming) that with custom firmware, we would be able to run 1.50 kernel. We may need to rely on some kind of Devhook kind of way to do this. I'm not saying emulating 1.5, i'm saying emulating a modified custom firmware that is basically 3.71 m33 for fat psp with 1.50 kernel, but modified in a way that it uses slim prx's. It would be complex, but that may be the only way we can do it for now.
And 3.71 m33 for fat sucks without 1.5 kernel.
I am lucky though, Dual booting 3.03 OE-C and 3.71 OE with UP. It seems that dual booting from flash is the only real use of UP anymore, and Devolution is completely useless unless you want to downgrade without a pandora...

With CFW now loading form a custom IPL, I say that 1.50 is not needed anymore. All that's needed is to port the homebrew to the 3.71 kernel.

I heard not all the PSP system resources are available in user mode (like the media engine.) That's why the more taxing emulators like Daedalus will never work with the PSP slim, or fat PSPs using 3.71.
That's why I haven't upgraded past 3.52 CFW too (plus popsloader works great for PS1 games.)

I'm very positive that this does not work with the slim so please please please DO NOT use this on your slim... I get tired of hearing these noobs whine about their bricked psps.
Personally the slim running only 3.xx CFW with no 1.50 kernel, i don't care too much, because as long as you have some kind of CFW running, the option for homebrew is still there. Also meaning down the road, the option for 1.5 homebrew will arise. Dont hesitate to get a slim, get one ASAP! while pandora still exists as a viable homebrew enabler.
I don't want to hear from anybody "I should have gotten one when 3.60 M33 and pandora still worked!!" just because you couldn't put up with no 1.5 homebrew for a few months.

-like 2 homebrew

Does it keep reseting at the Sony logo? Because mine does that. I just had to remove the memory stick and put it back in after the CFW boots up and it works again.
