No

Note: Plugging in an adapter during a 2.71 se firmware downgrade back to 1.50 causes bricks

when a psp boots up does it rely purely on the flash memory and no other source. Can the flash memory of a psp be considered the same thing as a regular pc's bios chip? If so then u could actually unbrick the psp with a way of forcing it to boot from something other then the flash itself ie. the memstick, because u can fix ur computers bio's if it gets messed up during a firmware upgrade by means of a floppy drive. Its just a thought. I know theres away around the psp booting from the flash.

No, there is no way of getting it to boot from anything else, it relies solely on the NAND flash. It is like a PC's bios, and the operating system in one... So as you can imagine, a corrupted or incompatible flash is rather fatal.

but a corrupted pc bios can be fixed by means of a floppy drive.

umm no. a graphics card bios can with a floppy set to auto boot but a pc bios cannot (unless you get one of those fancy dual bios - which is like the modchip on the psp).
with a faulty pc bios there are 2 options:
1. a hot swap (swapping good bios for faulty to flash it while machine is on) - not possible on a psp as the chip cant be removed.
2. total replacement of the bios chip - again not possible on a psp however the modchip is close to this idea.
now sony is reportedly able to reflash a psp through the com port however noone actually knows if this is true or even how it could be done.
cloudhunter is exactly right - a pc without a bios is useless in the same way as a psp is without the firmware files it needs to boot.

Yeah, on some PC's, very rare though...

When you are bricked fully though, the drivers aren't even loaded to run the firmware, so you cant run off the NAND and it doesn't even LOOK at the memory stick for its information...

nah b i unbricked my psp dude. i dont know what the hell happened. listen i had 2.71 and i tried to do that e loader crap and i... well... i dont think the e loader downgrader bricked it, i had the psp ac adapter hooked up to the way end of the room, and it came out with my battery. i turned it back on and BRICK!!! i forced it back off and back on and i had 1.5 running i dont know. i am not a genuis. i had retried this and it worked again. i am not a expert. i didnt even know how to update sony's firmware. oh well i dont know what happened. and 4 the record when i bricked it, there was no mem stick inside so i was like what eva and not i got 2 firmwares. its not impossible, just VERY unlikely.
