I'm trying to fix a phone (LG G3 Stylus) that has been badly injured, so now the touchsreen doesn't work, and the only button that works is the volume-up one.
I need to backup some stuff (notes, calendar, contacts, and some apps data), so I was trying to add a Google account to sync the data.
Now I was going to do this by using an OTG cable, so I bought one (USB 3.0 A to USB C that has a USB C to micro usb adapter) to connect a mouse, but it didn't work.
Now I found this solution to control the phone with a Windows PC but it needs USB debugging activated.
Now that's the problem. How do I activate USB Debugging without the touchscreen. I read that I could get into recovery mode, but the power button doesn't work. What can I do?
EDIT 1: I found another app that allows me to control the device: Vysor. Now I still require USB Debugging enabled.
Now I tested the other OTG cable (usb 2.0) and it didn't work either. But I found something: USB debugging was already turned on, but for some reason I can't find it when I run adb devices.
Anyways there are some random touches so I am waiting until the screen unlocks.
