Creo que esta ya puesto pero lo pongo por si acaso:
my 6 set PSP ^o^
1st PSP w/ FW 1.00
2nd PSP w/ FW 1.00 update to 1.50
3rd PSP w/ FW 2.50 Multi Firmware Mod 50% success (can't use FW 2.00, 1.50)
external FW 2.50, 2.60, 2.70
4th PSP w/ FW 1.51 Multi Firmware Mod 100% success
external FW 1.50, 2.00, 2.50, 2.60, 2.70
5th PSP w/ FW 2.50 Multi Firmware Mod 50% success (can't use FW 2.00, 1.50)
external FW 2.50, 2.60, 2.70
6th PSP w/ FW 2.01 Multi Firmware Mod 100% success
external FW 1.50, 2.00, 2.50, 2.60, 2.70
about 50% success :
in new ver PSP (FW 2.50/2.60 from factory)
it use new "protection"
maybe w/ new bootloader ?
so it can not use old ver FW
if you paste old ver FW in it
it will not boot
new ver PSP (FW 2.50/2.60 from factory)
it just can Upgrade
and can not Downgrade !!
How-To : PSP Multi Firmware Mod
copy PSP internal NAND Flash

program it to a samsung 32MB NAND Flash
2.60 new "protection" :
if you replace the flash0/vsh/etc/index.dat w/ old ver index.dat
when you power-on you will get a error screen
2.50 new "protection" :
if you replace the flash0/vsh/etc/index.dat w/ old ver index.dat
you will can not lunch update EBOOT.PBP
on FW 2.xx you also can not replace [new ver PRX files] with [old ver PRX files]

if anyone need 2.60 FW dump
you can use PspPet's PSAR Dumper w/o Decrypte to dump it
the dumped file is same as file in PSP NAND Flash(except "SIG check key")
PspPet's PSAR Dumper 2.0a w/o Decrypte prx file
this is not a new ver !!!

TODO : hot-swap, soft-swap, program nand flash on-the-fly...
Osease, todo esto es para integrar varios firms en una psp usando otra flash nand y para downgradear no vale para las 2.5 2.6 y 2.7 pero si para las 2.01 (por supuesto se supone que para las inferiores versiones tambien).
