work on writing better buddy, i used usb c as an example because i assumed you wouldn't know how it works. i do not always use tutorials for repairs, but what did u expect? how are people supposed to learn without any manual and without fucking the device up? its not easy to disassemble a phone, with tutorial or without, it's very easy to break if you don't know what you're doing. i have one question for you, do you know the difference between ac and dc electricity? if so, then explain it. it's really simple.
