Yea its very doable if you have a microscope, i really like the small repair stuff but i would not be shure if your local phone repair guy is able to fix this. If i were in canada i would take a look at it. Even if it is a 128gb drive i would at least try, either get experience or a working drive nothing to lose.
What did you use for pad replacement in your pictures? I have always used enamel copper wire but i also have seen people use premade pads to gluee on.
Man pages are also something underrated and tldr is great if you need a quick look at a few basic parameters of a program.
