Block Image Data (from XXD and Binwalk)

• /dev/mtdblock0 is a JFFS2 filesystem with the byte order big endian.

It is 64,356,352 bytes big. The JFFS2 filesystem starts at 0 bytes.

• /dev/mtdblock1 is an image that is all decimal 255 (hex FF). It is 64,356,352 bytes big.
• /dev/mtdblock2 is an image that is mostly decimal 255 (hex FF), but contains

(JFFS2, big endian) data between 00160000 and 0031fff0. It is 4,194,304 bytes big.

The filesystem starts at decimal 1441792.

• /dev/mtdblock3 mostly contains null bytes, but appears to contain cferam.000 between

00000000 and 00003bd0. It is 131,072 bytes big. Binwalk was not able to identify any data.
