SDRAM Key scan not working - read this carefully
You didn't directly address this one point, but does the fact that there are a few pictures already taken affect the ability to unlock it?
...
And what steps should I be repeating over and over? Do I have to keep getting new SDRAM keyscans, or do I just have to keep trying to push "unlock"?
Please follow my procedure that is posted here - it was the first legal hack for unknown keys and is the most up to date (if it isn't someone needs to recommend a change).

Older pictures on camera do not matter, but recent ones create copies of nvram.dat in memory and if camera is not left idle for serveral hours may produce corrupted keys. Your output indicates the second of 4 copies of nvram keys matched your challenge but not your response. That usually indicates memory decay or a bad cable. Did you wait several hours each time before repeating procedure to eliminate decayed copies in memory? And during short you must not disconnect for more tha 2-3 seconds or else memory can also decay. Did you take 2 pictures, delete 1 and plug camera in while still "hot" with display on - if not you can end up with bit flipped keys. Take a closer look at the 4 keys that sdram keyscan found - you may be able to create a valid challenge response pair by combining bytes that are the same in at least 2 of the 4. You can also use the following non shorting procedure to obtain your challenge and the last 124 bytes of a valid response (to combine with first 4 bytes obtained above). forumer.com/viewtopic.php?t=298" target="_blank">http://camerahacks.10.forumer.com/viewtopic.php?t=298
