# Tools to run the boot process

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