Allow USB debug pop-up not showing while installing CyanogenMod on Galaxy S3 i9300 I'm trying to install CyanogenMod on my Samsung Galaxy S3 (i9300, international). Had no problems, until I had to switch to the pc installer.

I'm stuck on the screenshot underneath: 



I have enabled USB debugging on my device (since the day I got it), did all the stuff asked up until now, but I can't continue here. It doesn't show any pop-up on the device, USB debugging is enabled.

Can anybody help me?

Much appreciated!
The solution to my problem was simply revoking all authorisations granted to computers already. After rebooting both my Galaxy S3 and my laptop, the pop-up appeared again and I could continue the installation of CyanogenMod, which has now succesfully completed.
