How to make the phone see the otg cable if the phone is a non-name brick that cannot be rooted?

Question

Android

Four times the most deeply respected all-knowing experts, help the stupid layman connect the otg adapter to the phone.
Problem 1: The phone does not see the cable. Google says that you need to perform tricky gypsy tricks and dances with a tambourine to create some kind of file in the permissions folder
Problem 2: in order to create a file in the root folder, I must have super rights. Ruth.
Problem 3: Chinese root programs display a sad emoticon and a bunch of hieroglyphs. Kingorut from PC does not want to see that I have enabled debugging mode on the phone. Kingorut from the phone wants to turn off my phone, and after rebooting and checking for root in several programs, it says that there is no root. about five other programs also say that we do not have your phone in the list.
I just want to connect a fucking flash drive to a fucking phone, but everything goes through the ass as always, and I'm poking around in the phone's system files for the fifth hour. - here is all the system data of my phone, I hope this will help you help me. Save.

Answer 1

Android version?
Does FlashTool see it?
Do you have a copy of the firmware? (not merged from the phone, but factory)
KingoRoot and everything else is yesterday, after Android 4.4 it makes no sense to use them.

Answer 2

Google seems to easily find the theme of 2014, whatever you want with your phone
