I'm not sure what happened last night, but I redid the dumps and got it working, it uses the same sector/offset as the other -A versioned OF, so it might be contstant values for the -A and -E versions? is the radio the only thing in the american version not in the eu version?

It was just a single byte in the other versions that changed from 0 to 1 (so possibly just a single bit). That includes the 1.00.12E firmware, which I think is just the European version of your (American) 1.00.12 firmware. I would expect a very similar structure between the two. This page: http://www.rockbox.org/twiki/bin/view/Main/SansaE200FirmwarePartition has a breakdown of the firmware partition structure that I know of so far. As you can see from that page, the database rebuild flag is just a part of the NVPARAMS section of the partition. There's lots of other stuff in that section such as resume info, etc, so some of that may change between boots too. I guess it's just a matter of trial and error, there are only 3 bytes so it shouldn't take too long.
