Post by RomShillzz » Thu Feb 07, 2019 10:56 am

Got a device with broken touchpad and it requires you to Allow USB debugging (authorize RSA Key) when connected to your Computer in USB Debugging mode? It pops-up with a USB debugging prompt on the phone as shown in the image below.

Allow USB debugging?

The computer's RSA key
fingerprint is:

☐ Always allow from this computer
On this tutorial, I'll be showing you on how to bypass this prompt on the device with a broken touchpad.

Another Android device running Android version 4.4.2 and above, with USB debugging enabled and the same computer authorized from that device.

How To Fix:
#1. Connect the other device to your computer (the one without a broken touchpad) after enabling USB debugging, when you get the "Allow USB debugging prompt", check the "Always allow from this computer" and click "OK".

#2. "adb_keys" is the file we need from the authorised device which is located in /data/misc/adb/ inside the device storage.

To get the "adb_keys" from the authorised device, open CMD (command prompt) in your computer and input the following commands.

Code: Select all

adb devices
adb pull /data/misc/adb/adb_keys c:/adb_keys

c:/ is the location you would like the "adb_keys" to be saved to, so it can be any destination path.

#3. After successfully getting the "adb_keys", Reboot the device with bronken touchpad into "Recovery mode" and connect to your computer (in recovery mode).

#4. Open CMD (command prompt) in your computer and input the following commands.

Code: Select all

adb devices
adb push c:/adb_keys /data/misc/adb

c:/ is the location (destination path) you have saved the "adb_keys" to in step #2.

#5. After copying the "adb_keys" into the device with broken touchpad via recovery mode, input the following commands to reboot the device from the recovery mode.

Code: Select all

adb reboot
Now the device will reboot to normal mode, connect the device to your computer it will be automatically authorised!

If this worked for you, use the thanks button!
