Were you able to make a dump of the 1.00f firmware of your powershot?  If yes, which way did you do?  With blinker method?  Or with pure software method?


I used the pure software method to dump the firmware. FYI, my S80 has firmware ver 1.01b.

A620 and SD450 are relased from canon at almost the same time as S80..
Maybe we can learn something from these builds?

Comment I don't think it possible to run orginal bios from SD card, at all..
Maybe I'm wrong, but, also if U where right will not the firmware read from the rom address of original FW, the id?

:)

Been trying to dump my PS s80 gm1.00H firmware to save a copy of it before I downgrade to gm1.00G in order to use the beta CHDK for my Canon PS S80. 

I've used Cardtricks to get the dump but when I use the clean function it just runs forever and last popup message says "Trimming 11800064 Trailing 00".  I don't find any output of a bin file at the designated folder either.

Has anyone else tried to do this with the PS S80 firmware GM1.00H?

I'm not even sure if I should bother worrying about the downgrade back to G since there is no CHDK for that version anyway.
