Can't authorize Redmi note 10S

[DellandY]

Hello, so recently ( 20 days ago) i broke my phones screen, and i was using scrcpy for this phone on many devices, but now no of them have access for it, my pc, my laptop, bro's pc and mom's laptop non of them have access to its adb

when i use "scrcpy" it gives this :
C:\Users\Admin\Desktop\scrcpy-win64-v3.3.4>scrcpy
scrcpy 3.3.4 https://github.com/Genymobile/scrcpy
ERROR: Device is unauthorized:
ERROR: --> (usb) 8DLBWOYPYHGUCI9D unauthorized
ERROR: A popup should open on the device to request authorization.
ERROR: Check the FAQ: https://github.com/Genymobile/scrcpy/blob/master/FAQ.md
ERROR: Server connection failed

and when i use "adb devices" it gives this :
C:\Users\Admin\Desktop\scrcpy-win64-v3.3.4>adb devices
List of devices attached
8DLBWOYPYHGUCI9D unauthorized

i tried taping on screen to find the accept button, but i think the left low corner of touch screen is working, i tried "scrcpy --otg" but no luck, i didn't turn on "wireless adb"

pls help, and thx in future (sorry for bad english)

That "unauthorized" error is a nightmare when your screen is dead. Basically, your phone is asking for permission to trust the computer, but you can't see the "Allow" button to tap it.

Since --otg mode isn't helping (usually because the phone is locked or ADB isn't fully ready), we have to get creative to hit that "Allow" button. Here are three ways to try and fix this:

1. The "Blind Tap" with a Mouse (If you have an OTG Adapter)
   If you have a small USB-to-Phone adapter (OTG), plug a standard PC mouse into your phone.

The Trick: On most Android phones, the "Allow USB Debugging" popup appears right in the middle of the screen.

Action: Connect the mouse, wait 5 seconds, and try to click exactly in the bottom right of the center area. Even if the screen is black, the mouse pointer is still there!

2. The Key-Combo Hack (No screen needed)
   If you can't see anything, try using a physical keyboard via OTG:

Connect the keyboard to the phone.

Wait a few seconds for it to register.

Press Tab once or twice.

Press Space or Enter.
This often selects and clicks the "Allow" button in the popup window.

3. The "Keyevent" Command (Long Shot)
   Since your device is showing as unauthorized, the adb shell commands usually won't work, but sometimes you can "force" a keypress if the phone is partially authenticated. Try running this in your terminal:
   adb shell input keyevent 66
   (66 is the code for "Enter").

4. Forcing the Authorization (The Desktop Method)
   If you ever used this phone on a different PC in the past, go back to that specific PC.

The authorization "key" is stored in a folder called .android on your computer.

If you can find a computer that was authorized before, scrcpy will work instantly.

Copy the key: You can actually copy the adbkey and adbkey.pub files from a working PC's .android folder to your current PC's .android folder (usually in C:\Users\Admin.android).
