On the Wiki, it says the SD750 (IXUS75) is supported with:
Fw: 1.02a, (1.02a with CHDK version for 1.02a)
I have this camera with that firmware, but on the Wiki page for SD750, it says that the firmware for 1.01a is complete, and 1.02a still crashes.
Why does it says 1.02a in the Wiki, and is it possible to change firmwares (downgrade)?
