There is one more problem... Even if I find some patch, then now do we test it?
We don't know what would happen if the patched firmware would crash. Would the unit be able to flash GCD files then?
[Only registered and activated users can see links. Click Here To Register...] Neil was talking about some kind of a "pre-boot" mode. And I've seen some gupdate.gcd parsing code in the bootloader. But all these facts doesn't imply that we could restore the unit by flashing gupdate.gcd if patched fw_all.bin crashes.
