I flashed OpenWrt CHAOS CALMER (Bleeding Edge, r43793) using the stock web interface of the device. Just connect the router with an Ethernet cable to a network, it will switch on the blue and red LEDs. Find you the IP address from the DHCP server, and log into the router using your web browser. 
Login: admin
Password: admin
Switch the language to English from the drop down menu. I got reconnected to a wrong IP address, so I had to type the correct one again in the URL field of the browser, then the interface was English. Using the Administrator -> Firmware menu, I flashed https://dl.dropboxusercontent.com/u/98389203/openwrt-ramips-rt305x-a5-v11-squashfs-factory.bin

Or, if you want to make the image yourself, use the OpenWrt Image Generator:
wget https://downloads.openwrt.org/snapshots/trunk/ramips/OpenWrt-ImageBuilder-ramips_rt305x-for-linux-x86_64.tar.bz2
tar xfj OpenWrt-ImageBuilder-ramips_rt305x-for-linux-x86_64.tar.bz2
cd OpenWrt-ImageBuilder-ramips_rt305x-for-linux-x86_64/
make image PROFILE="A5-V11"

They DELETE the video after one week? Must be a joke.

First, view the ARD page with the video to be downloaded. It access a master.m3u8 file.

I got cheap ESP8266.txt modules from China and was struggling to get them working electrically. It turns out they are very power hungry, in fact, when you use a serial adapter to power them, most likely they will crash the serial adapter due to their power draw. For this reason, I was not able to communicate with the device for a long time.

This setup works for me:
Solder VCC and CH_PD pin together (TODO: Check whether using a 1k pullup resistor changes the overall power consumption). Use a Prolific USB serial adapter to provide the 3.3V and GND, use another(!) serial adapter connected to the same USB hub (so that they share GND) to provide the RX and TX pins for the serial connection. This setup might not be the cleanest, but it was the quickest for me to get up and running.

According to my measurement with a cheap USB "Charger Doctor", the device draws 470 mA when hooked up to a Prolific serial adapter for providing the 3.3V.

My module had the following firmware pre-loaded:
