How can I automatically boot Original Sansa firmware instead of Rockbox?
AlexP:
And those are all different devices.
whiskers75:
There is a way, but unless you know assembler and are willing to risk bricking your player, no.
Crafty:
hmmm,
does USB/MSC code run before the bootloader?
And is the USB/MSC code burned on ROM?
The factory has to have some way of loading OF.

No.

Yes, but that doesn't necessarily mean they have to access the memory via USB. The factory has access to the PCB so they can use internal interfaces.

They probably flash the NAND chips before they solder them onto the board.

They use NAND rather then a traditional ROM, I guess to cut costs. If you screw up a firmware flash its extremely difficult to fix it.
