Some people asked me how to recover a fonera, here are some methods:

methode 1:
    Press the reset button for > 15 seconds
    This requires a working Fonera
    Sometimes it didn't work for me.
    
methode 2:
    Run "rm -R /jffs/*" and pull the plug
    It should result in a reseted fonera
    
methode 3:
    If everything fails and you killed your shell on the serial console:
    As soon as you see "Please press Enter to activate this console." press Enter
    Now you have to hurry up!
    Paste "cat /proc/mtd" and press Enter (even if you don't see your pasted line)
    You should see this list:
        dev:    size   erasesize  name
        mtd0: 00030000 00010000 "RedBoot"
        mtd1: 006f0000 00010000 "rootfs"
        mtd2: 00560000 00010000 "rootfs1"
        mtd3: 00010000 00010000 "config"
        mtd4: 000b0000 00010000 "vmlinux.bin.l7"
        mtd5: 0000f000 00010000 "FIS directory"
        mtd6: 00001000 00010000 "RedBoot config"
        mtd7: 00010000 00010000 "board_config"
    
    Search for the "rootfs1" line and take the number of the beginning of the line (mtdX)
    
    Now you have to reboot again
    Press Enter again but now paste this line:
    	echo -ne '\xde\xad\xc0\xde' > "/dev/mtdblock/2"
    Make sure you're using "/dev/mtdblock/X" (the mtdX number)
    Now reset it again and you should receive this message:
    
        Please press Enter to activate this console. jffs2_scan_eraseblock(): End of file system marker found at 0x0
        jffs2_build_filesystem(): unlocking the mtd device... done.
        jffs2_build_filesystem(): erasing all blocks after the end marker...
        
    This takes some time but you should have a fresh fonera again.
    
    If this doesn't work you probably have to use a JTAG cable.
