/* How it works:
|
||||
*
|
||||
* - dualboot-installer: installs or updates a RB bootloader, the bootloader
|
||||
* to install/update is already included into dualboot-installer.dfu file,
|
||||
* once it is executed by the iPod device:
|
||||
*
|
||||
* 1) locates an original NORBOOT (ONB): first it looks at offset=32KB, if
|
||||
* a NORBOOT is found but it is not an ONB then it is supposed it is a
|
||||
* RB bootloader (that should be updated), then the ONB is loaded from
|
||||
* offset=32KB+old_BLSIZE).
|
||||
* 2) write ONB at 32KB+new_BLSIZE, if it fails then:
|
||||
* 2a) try to restore ONB to its 'pristine' place (offset=32KB), if it
|
||||
* also fails then the NOR got corrupted (ONB probably destroyed)
|
||||
* and iTunes should be used to restore the iPod.
|
||||
* 3) write new (included) RB bootloader at offset=32KB, it it fails then
|
||||
* goto 2a)
|
||||
*
|
||||
* - dualboot-uninstaller: uninstall RB bootloader from NOR, leaving it at
|
||||
* it's previous (pristine) state.
|
||||
*
|
||||
* See bootloader/ipod6g.c for notes on how the RB bootloader works.
