[NAND blanker]

[wraggster]

A small firmware which boots off a FAT32-formatted SD card and totally blanks the kernel, filesystem and user portions of the NAND fixing 'bad block syndrome' often caused by 3.0->2.0 downgrades (though it can happen simply by writing to the NAND often enough).
It leaves the bootloader in tact.
