So that it was possible to debug applications on the device, on the old Chinese android it was done easily in the options, it was enough to install the driver, but I don’t understand how. Tell me who is in the subject, I nagulit some kind of universal driver https://github.com/koush/UniversalAdbDriver I do not know whether to help or not, while poking like a blind. Yes, I entered the engineering menu, where it didn’t help too much 7 times.



adbphone sees, connects, and so on. After unlocking the "For Developers" menu (by repeatedly clicking on the MIUI version in the "About phone" section), in this very menu, you must directly turn on "developer mode" and also enable "USB debugging". It seems like nothing else is required. - Yaant
