Unlike the desktop computer market, each PDA/phone model is unique and
the OS kernel must be customized to run on it.

The mtype parameter is an internal code shared between boot loader and
kernel that allows the kernel to verify it is running on the hardware
it was built for. (In some rare cases, this could allow a single
kernel to run on two different devices by detecting the mtype and
loading a different "personality".)

You need to write (or find) a customized kernel for your device. If
the kernel does not say it supports "HTC p6300" then it will not run
on your device.
