= MediaTek Romloader =
Just like the [wiki:CalypsoRomloader], the the MTK romloader is a serial bootstrap-loader inside the Digital Baseband Processors manufactured by MediaTek.
It is executed when the power button of the phone is pressed, and listens on the UART for the an 0xa0 activation byte.
The loader can read/write from/to all registers and memory addresses of the DBB, which is used extensively by the host software.
Most of the initialization logic is therefore in the application on the host, which uploads the code to the phone.
