Device: Asus WL-500g
Firmware: 1.9.2.7-7b

I am booting from USB and I would like to upgrade the firmware of my wl-500g. I’ve read in this forum that mtdutil is the command for this but I can't run it my Asus (-sh: mtdutil: not found). Can somebody give me some light on why this happens?

According to this forum, it should be enough with:

Code:
mtdutil upgrade /dev/mtd/1 /tmp/linux.trx
Where /tmp/linux.trx is the path and file to the new firmware version.
