Hi, I vanviso very interesting tutorial. Although, I think you are assuming that anyone how follows it is very familiar with Linux systems. But, what about those new people who want to get into mining and do not know anything about Linux or android. There are some parts where you use the word "files" and you do not mention the name of the files. In the fifth paragraph you say "Now we need to uncompress the android system image. Fortunately, we have a tool for that" it would be very helpful to have the names of the tools and the commands to retrieve and the commands to use the tool. Always remember when you are doing a tutorial that not everyone is an advance user. Especially if you are the first person writing a tutorial on the topic, you want to give as much information as possible.
