How to authorize and accept ADB RSA key with broken touch screen on Android [closed]

Question

My Nexus 7 2012 has a broken touch screen so I use an OTG mouse with it. I recently had to do a factory reinstall so am running v5.1 lollipop. The problem is I now have to re authorize adb with my computer so I can do work on it but cannot accept the RSA key when the dialog pops up because my touch screen is broken.

I cannot use my otg mouse because the Nexus 7 is connected to the computer, I have tried a bluetooth remote android device app which fails to work when the dialog shows, I have tried using another remote android app over wifi, I have tried using my computer keyboard via telnet but fails to work when the dialog appears. I don't have a bluetooth mouse but don't even know if that would work.

Does anyone have any suggestions how I can accept the ADB RSA key dialogue to authorize adb with my computer without the use of a touch screen. Thanks?

Answer 1

If you are using macOS (or any Linux distro):

1. Reboot your phone into recovery mode.

2. Connect it to your computer.

3. Open the terminal and type:

    cd ~/.android
    adb push adbkey.pub /data/misc/adb/adb_keys
   

4. All done! Just adb shell reboot and feel the power!

*For Windows 10, .android directory is located in your the base of your C:\User\user_name directory.
