You can easily customize your Android device through the phone settings. But if you’re looking for more ways to modify your phone, you can do so through the Fastboot mode on your PC. This mode allows you to install your own Android or recovery version, giving you more control over your device. In this article, we will explain what you can do in this mode and how to start it.

Please note that while most Android devices refer to this mode as “Fastboot,” Samsung devices call it “Download.” For better readability, we will refer to it as “Fastboot” in this article.

How to start Fastboot mode on Android?

The method to start Fastboot mode varies depending on the manufacturer of your device. Generally, you need to press and hold the volume down button and the power button simultaneously. On Samsung smartphones, you need to press and hold the volume up button, power button, and the home button (Bixby button) together. For devices without the Bixby button, press the volume down button additionally. These combinations will take you to the Fastboot menu.

Sometimes, your smartphone may start up normally. In that case, you need to repeat the process but connect your smartphone to your computer using a USB cable before starting. The Fastboot menu will have a different appearance compared to the regular Android screen. Also, you don’t need to unlock your device to access it. You can navigate through options using the volume up and down buttons, and select options using the power button. Here is an example of how the Fastboot screen looks on a Samsung smartphone. Don’t worry if the options are displayed in multiple languages.

What can you do with Fastboot mode?

Fastboot mode, along with the recovery mode, is mainly meant for repairs and manual updates on your device. However, you can also make specific changes to your phone using this mode, such as installing your custom Android version. To do this, connect your smartphone to your computer using a USB cable while in Fastboot mode. Ensure that your device has enough battery, as the power from the USB connection may not be sufficient for the process.

From your computer, you can then write to partitions on your phone. These partitions are different “areas of responsibility” on your smartphone that you can customize. For example, you can modify the bootloader, radio, and splash screen. However, it’s essential to be cautious about what you change. Making incorrect settings through Fastboot commands can potentially damage your phone’s software, and it may be irreparable.


With the ability to customize your Android device further through Fastboot mode, you can explore new possibilities and personalize your smartphone experience. Just remember to proceed with caution while making changes in this mode.
