Android USB Debugging is not showing the authorization dialog

Question

I need help with USB Debugging...

I've been trying to allow my computer to debug my phone for ages. It has been frustrating. I have installed all required drivers. My device is detected through adb devices but it is unauthorized. No matter how much i try, the authorization dialog on my android is not showing up.

If you want to tell me to go to do something to the root files, i can't. My phone is still original, and unrooted. Yes, i have changed to PTP. I also have installed the latest sdk platform tools from SDK Manager. I use windows, and using adb with cmd.

Please help!

Solution

I had the same Problem.
I solved it by manually copying my adbkey.pub (from ~/.android/) to the phone at /data/misc/adb/ and name it adb_keys. I placed the file via mtp on the internal sdcard and moved and renamed it in place with a filebrowser on the phone. Obviously you need a rooted phone to do that....

In short:
copy from your computer ~/.android/adbkey.pub to the phone as /data/misc/adb/adb_keys
