Perhaps I was reading your instructions too literally.
Here is my update instructions that seem to work and
produce the mainArduino.bin file. I have not tried it
yet.
Ps: I have not had a hang since Aug 1. No change to the
firmware and no change on my network!

#Get the code.
git clone https://github.com/OpenSprinkler/OpenSprinkler-Firmware.git
#Puts it in ~/OpenSprinkler-Firmware/
#Get the Arduino code.
git clone https://github.com/esp8266/Arduino.git esp8266_2.5.2
#Puts it in ~/esp8266_2.5.2
#Go into esp8266_2.5.2 and get the correct tag.
cd esp8266_2.5.2
git checkout tags/2.5.2
cd tools
python get.py
#Install necessary libraries, including SSD1306, RCSwitch, and UIPEthernet.
#Download and unzip or git clone these into ~/Arduino/libraries folder.
mkdir -p ~/Arduino/libraries
cd ~/Arduino/libraries
git clone https://github.com/ThingPulse/esp8266-oled-ssd1306.git
# The latest version of the OLED code is not compatible, backup to 4.1.0
