@VbScrub thank you very much for taking the time to answer my post! It is definitely something for me to look into as further reading! My problem turned out to be something a lot more trivial, but it’s definitely worth learning more about why the tools listed here work and how they work. The tokens listed make a lot more sense to me now and I wish that the walkthrough also explained it with the same level of detail! I also found the forums a little bit restricting when pasting commands! 
I have managed to root it, turns out the walkthrough has been omitting some steps and has a command that leads to an incorrect output (echo command with the forward slashes, which don’t end up in the final file due to the forward slash being the escape sequence). I will post a proper explanation in here soon.
