I'm using TomatoUSB on an Asus RT-N16 some time without problems. Yesterday I got a second RT-N16 and tried to install TomatoUSB again, using these instructions:
tomatousb.org / tut:installing-on-asus-routers-rt-n16-etc-in-linux
But it did not work. After transfering the image via tftp and waiting 5 minutes, the router goes into recovery mode after power off/on.
I found a document, saying that the NVRAM was increased from 32kb to 64kb with the update from 188.8.131.52 to 184.108.40.206.

Can this be the cause that the installation fails? (because the flash layout changed?)
