I made a modified rootfs that does the workaround for the boot loop. It simply is the guts of the data.img from the 3-31 build in a tar file. It seems to loop on the setup but that maybe because i'm doing it on wifi. If you just hold the power button and reset the phone it will boot to your home screen on the next boot. The patch.tar.gz file has the linux permissions so if you must edit windows will most likely break the patch.
