The following tools can be used to update the boot configuration:

* QDTE
* Fastboot

You can access QDTE, a GUI editor tool, from the [Qualcomm Software Center (QSC)](https://softwarecenter.qualcomm.com/#/), whereas Fastboot is a diagnostic tool that offers a Recovery mode known as the Fastboot mode. The tools for the boot process include:
