Screen broken how to enable USB debugging? - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hi,
I need some help from experts.
My screen is broken and black, I can't interact with phone anymore but i know it is booting properly.
I think the only option for me is to stream the screen through adb using a tool like Vysor.
For this I need adb but usb debugging is off. I can access fastboot though.
Question, is there a way to enable USB debugging is this kind of situation?
Any other ideas?
Thx

USB Debugging problem

Hello guys, I need help to root my phone. After I click on USB Debugging (on Developer options), the option turns off itself and then I can't connect with the PC. The problem is on the phone, I have updated the drivers on pc, installed Lenovo Manager but didn't work. What should I do? Thanks!
Nobody?
Nobody? I think the problem is like usb debug process crashing on android, because it turns off itself.

Broken screen, USB-debugging disabled SM-A500FU (Galaxy A5)

Hello, so I got this phone which has a broken screen, but otherwise it can connect to a pc, so its not completely broken, but before I atempt to replace the screen I would like to test the phone by mirroring it's screen to pc, but unfortunately USB debugging is disabled, since using adb devices lists no devices. Im using chrome and vysor app for chrome, it works on my other phone with debugging enabled.
The A5 supposedly has stock firmware installed, but the user is not sure which version. Is there a possibility of enabling usb debugging via some patch using odin? does chainfire root maybe auto enable debugging?
I'm sorry if a similar thread exists, but I couldn't find it unfortunatley, if it does, please post link, or help otherwise if you know how, thank you.

nexus 4 - broken screen and usb debugging turned off

Hi
I have a nexus4 that has a broken screen, it is, it doesnt react to the finger touch, and doesnt have usb debug enabled
What could i do to extract the files from there?
I have seen that connecting a mouse via usb is not an option as this device is not compatible with that, so i think the only option i have is to flash the device to have usb debugging enabled
Is there any other option i can explore?
Thanks
I am sure that you can enter your recovery assuming that your power + vol button is still functioning.
Try to connect your device using Wug Tool and use the tool to back up all the files.
Give it a try and let us know.
Sent from my Nexus 4 using XDA-Developers mobile app
Thanks
Yes, i can get in recovery, but, i assume i would need to unlock the bootloader first, isnt it? If i do it, i will erase all the documents inside
Hi
I have tried getting into recovery, but, as expected, as usb debugging is not enabled, i cant see the device from adb
So, the key question is... how can i enable usb debug in a device with the screen broken and with bootloader locked, without wiping the data?
Thanks
It is possible to turn on usb debugging?
I have clean phone - after factory reset.

Help Screen Broken, Need To Enable MTP Mode

I just dropped my phone and the screen no longer works but the phone does. I plugged it into my computer but I remember that when I have done that in the past I had to change it from charging mode to MTP mode using the screen. Is there anyway to change the phone to MTP mode without using the screen so I can get my files off of the phone?
Thanks
Was USB debugging enabled before? and if yes have you authorized your computer for the phone before?

How to recover files from a phone with broken screen? (OP6T)

Hi, I'm an OnePlus 6T owner and I have problem. I recently broke the display of my phone and now the screen can't turn on. Is there a way to extract the files from the phone? My default mode for connecting to a computer is charging and I can't simply transfer the files to my PC. Also, I don't think I have USB debugging on. If anyone knows a method that I can try, please post it.
I don't know if this requires usb debugging to be on but trying "adb pull" might work.

It does.
The first thing I do is turn on USB debugging on all my phones.
Right after BL unlock and root that is.
