You basically just gave us a guide on how to brick your device. The 3t uses DM verity so you need to install a kernel without it or allowing modifications prevents the phone from booting.
Is that something new? I have been rooting my 3T, on stock kernel, since release without problems – just skip the DM verity message at boot. Is this changed?
