Did anyone know this:
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
I think this means no downgrader ever for 2.01+.
