What is ADB and Fastboot?
Let’s talk about the special software that is ADB and Fastboot which will help us update our Sonim devices.
We will now focus on the options available with Sonim devices, but first, it will be pertinent to know ADB and Fastboot are crucial tools used for system updates on the Android operating system.
ADB (Android Debug Bridge)
ADB, or the Android Debug Bridge, is a command-line form of communication with the device. Its primary functions include numerous practices like debugging, controlling and managing applications, transferring files, and remotely operating devices. ADB also assists in updating the devices by granting access to specific internal components within the System.
ADB Features
- Installing and uninstalling applications
- Moving files from a computer into the device and vice versa
- Debugging and gaining access to the device logs
- Changing device settings, including booting for various processes
Rooting, custom ROM flashing, and System updates are some of the processes which ADB helps users accomplish. It allows users to control the devices via commands as the users cannot do so through the GUI interface.
Fastboot
Editing the system partition of an Android device while it is either in Bootloader or fast boot mode is the function of fast boot. Fastboot is quite different from ADB. This is because fastboot is able to allow changes to both the bootloader and system partitions. Such changes are necessary for several reasons, like unlocking the Bootloader, flashing, or unbricking devices.
Fastboot Features
- Allows flashing of custom ROMs, kernels, and recovery images
- Unlocking of Bootloader
- Boot Image Restoration or repairs
- Update the system partition with either Stock or Custom ROMs
Fastboot commands interact with the device at a low level and, hence, are more advanced and complex than ADB. Fastboot is typically performed when performing more advanced updates, new system image installations or recovering bricked devices.
