β€’Β Jim’s unsqhashfs instructions

On May 27th we’re spending the whole afternoon (1–6 p.m) hacking away at an old Tenda FH1206 router, with the goal of installing open firmware such as OpenWrt or FreshTomato. We have plenty of routers to go around, which we’re selling for $8 each. Proceeds will be split evenly between Philly Community Wireless and Iffy Books.

This will be an informal event, more like a hackathon than a structured workshop. We recommend bringing a laptop if you have one.

We’ll also be selling used electronics, including desktop computers, monitors, peripherals, cables, and TS-7600 single-board computers. Come early before they’re picked over!

1–3 p.m. Orientation
We’ll show you how to examine the router firmware and gain root access via telnet.

3–5 p.m. Soldering session
You’ll learn to access your router’s serial shell, which requires soldering a few wires to the board.

5:00 p.m. Progress reports
We’ll go around the room and talk about what we’ve learned.

The routers we’re trying to hack were sold under the name Atlas Media AMW-DBR1200AC, but they’re actually repackaged Tenda FH1206 routers.

Here’s a blog post with our progress on the router so far.

There's a green piece of paper taped to the box with the following text: "$8 Challenge Router / Can you install OpenWRT on this router? We'll give $100 to the first person who can show us how. / You can also use it as a regular router! / Proceeds benefit Philly Community Wireless & Iffy Books"
