TS-7250's do not use JFFS2. They use YAFFS since the flash is a NAND
chip. You cannot work with filesystem "images" with YAFFS. You
have to erase the filesystem completely (either with rm -rf or
eraseall /dev/mtdblock/1) and extract your new image onto the
mounted filesystem. This way, YAFFS will auto-discover the bad
sectors as you are extracting and work-around them.
