If I install this on 3.30, could I upgrade to 3.40 OE-A on 3.30?
I'm pretty sure. Search around=P
EDIT: Yes it can. You can run older firmwares see:
i think that you write the flash of 3.40oe-a or something it boots up by itself on the chip and not the psp flash if ya hold l1 on bootup it uses psp flash so yeh there good
