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.

hey, OK, so the other e200 I have here does actually have a different OF from he 2 we know the locations of the byte to change. I've done the two dumps and used got the diff, but I cant remember what the previous diffs looked like so cant actually add it to the BL... did they all have 3 bytes changed?

(also a change to e200-buttons.c to get buttons working in the BL again, although, enabling the interupts would be better probbaly?) I'm going to bed, have fun at devcon :)
