What these instructors fail to realize is that most of us haven't been using shell commands since we were 11 years old.
I'm not even sure how to start ADB sideload. I just downloaded a whopping 389 mb package for the entire sdk when all I needed was adb sideload.
(but I couldn't find any place to download just the adb sideload).
Now when I double click on adb, the black screen comes up for two seconds and I see a whole bunch of lines scrolling down and then the black screen disappears.
There are lots of guides on how to use the Android Debugging Bridge (ADB) here on xda. It is a fairly complicated process to set up AND use effectively, at least for me it was! But once you get it, ADB is an extremely powerful tool. If you already got the Android SDK and edited your environment variables (i think that's what it is called), you simply open up command prompt and can use adb from any directory. But depending on how you set it up you may have to use "cd C:/" to use adb. Anyway i think I wasted your time with some nonsense, i have the thread around here somewhere that teaches about adb
