can the psp be downgraded simply by running the FW1.50 update?

Have you tried restoring default settings? If that doesn't work, you need to put the 1.50 eboot in the GAME/ RECOVERY folder and launch it from the recover menu

And also, mapThis users like myself who are afraid that there'll be problems with mapThis after upgrading to this firmware...i'm glad to say tat there shldn't be any problems..! Tested n proven - at least for my set... =)

Anyway...one difference tat i've noticed is when i go into my Memory->Game Menu, there's a bit of lag while scrolling up and down my games and applications...anyone noticed tis too?

1.I havent used mapthis.
2.thats because the cpu is set back at default 222

Just reinstall this custom firmware... but next time back up before custom theming ( thats why it keeps freezing)
you dont need to downgrade to 1.5 first

Anything that isn't OE just doesn't seem safe to me. Ill just wait a while and see how things develop.

but wouldn't load the 1.50 FW eboot.pbp

How strange, do you have the 3.40 oe (or w/e c-fw you were using before) update you made? That should work. Else you could try reinstalling 3.51 m33 using the recovery folder.

OK im running the 3.51 M33 Firmware creator now.
Writing 3.51 firmware... OK.

edit:
so now i just have to take the newly created EBOOT and put it in the recovery folder right?

NO WAY!!! I haven't really seen anything worth posting to lately (which is why I've been missing) but this is defiently worth it. I'm gonna be installing this, I just hope I don't get the same problem as Xcliber.

Ive looked at 3 different forums and lots of people saying they upgraded succesfully, and not one saying they bricked and/ or anything bad about it.

lilswish- that was nothing to do with the firmware... he didnt backup before he tried flashing custom themes
