Comment(by kho):

 When I try to upload the root fs from my Neo Freerunner to the PC with
 dfu-util as mentioned in the http://wiki.openmoko.org/wiki/Pre-
 Flash_Backup page, I get an error near the end of the upload operation -
 the good-rootfs.jffs2 file has size 258076672 at that time.

 $ dfu-util -a rootfs -R -U good-rootfs.jffs2
