Properly migrating app+data backup from one phone to another with a broken digitizer
I wanted to be able to use ADB's ability to simulate touch input to pair a bluetooth mouse to my phone, but it does not seem like this is going to be possible because I am running 4.2+ which requires RSA fingerprint authentication... which none of my computers have permission for.

I will order a USB 3-way Y cable and use a hack version of USB OTG to plug in a physical mouse. I can do this because I can use ADB through fastboot to temporarily boot a non-touch CWM recovery, then use ADB to push the modified kernel img and flash using the non-touch interface, which should then hopefully boot up. Since I'm on CM10.2 I already know Franco Kernel causes soft-brick, so hopefully the modified OTG stock kernel does not cause soft-brick. Once I have the phone fully booted, it should just be a matter of connecting a power source and pointing device to interface with my device.
