Tenda N300 firmware binary - no supported filesystem found.

[huckleberrypie]

So I bought a cheapo router off some online store, but while the device ran fine for my needs the web-based UI only came in Chinese, and I'd like to at least edit the HTML files so I don't have to fiddle through things. I ran it through binwalk and saw that it was an LZMA-compressed image of some sort.

extract-firmware.sh results in this:

Tried uncramfs_all and extract-multisquashfs-firmware but it didn't result in anything useful either. I've attached the firmware binary below.
