FastBoot Mode

What is Fastboot?

Fastboot is a protocol that can be used to re-flash partitions on your device (update the flash file system in Android devices). It is this small tool that comes with the Android SDK (Software Developer Kit), which is an alternative to the Recovery Mode for doing installations and updates.

Not all phones have a fastboot mode that the user can access. It’s turned on with Nexus devices by default as well as a few other phones and tablets and has been enabled by independent Android developers and enthusiasts on some other phones.

 

What is Fastboot for?

While in fastboot, you can modify the file system images from a computer over a USB connection. Fastboot mode can start on your device even before Android loads, even under the circumstance when Android isn’t installed at all. And because of that, fastboot mode is useful for quick-updating the firmware, without having to use a recovery mode. In fact, it’s the preferred way to initially install the recovery image. Once you set up, you boot to your phone to fastboot and you can flash image files to the internal memory. Flashing a custom recovery like ClockworkMod is a popular use case. The images you flash don’t need to be signed with a particular key, and thus you should use care when flashing. It can also be used for developer operations. Things like erasing partitions and overriding kernel command line options can be done. And all this features make the tool very useful for developing hardware and software solutions, like unlocking the Bootloader of Google’ Nexus.

 

How to enter Fastboot?

As said, not all phones have a fastboot mode that the user can access. It’s turned on with Nexus devices by default and has been enabled by independent Android developers on some other devices. So before you proceed, one thing is to make sure your device actually have a fastboot mode.

Entering Fastboot also requires the Android SDK (Software Developer Kit), and different USB drivers for Windows computers.

Know Your Android Tools: What Is Fastboot & How Do You Use It?

If you've ever owned an HTC device or anything in the Nexus line, odds are, you have typed the word "fastboot" into your command line at one time or another. That said, odds are, you have only just barely scratched the surface of what this handy little Android tool can do. Let's take a deeper look.

What Is Fastboot?

Fastboot is a tool/protocol for writing data directly to your phone's flash memory. In practical use, it is used to flash images such as recoveries, bootloaders, and kernels to your Android device. Outside of the obvious, you can also restore nandroid backups, change your splash screen, and flash system updates.

Fastboot can do very little without a rooted device and an engineering SPL (secondary program loader), meaning the bootloader, or HBOOT for HTC. If you have a Nexus device, you don't typically need to mess with your SPL, as your device comes from the factory with a fairly capable bootloader.

Just like ADB, fastboot is included in the Android SDK.

Step 1: Installing Fastboot

Downloading the entire Android SDK if you only need fastboot is overkill. Thankfully, it is possible to download and install the specific tools that we need in just a few easy steps, on all major operating systems.

Windows Installation

Getting fastboot to work on Windows can be a little challenging. Thankfully, XDA forums user Snoop05 created an installer that massively simplifies the process, by installing both Fastboot and ADB, installing the necessary device drivers, and adding these tools to your system PATH (allowing them to be run from any folder via the command line), into a 15-second operation.

Simply download and run the installer. You will be asked if you want to install ADB and Fastboot—type "Y" and press enter. It will then ask if you want to install ADB system-wide—again, type "Y" and press enter. After that, it will ask about installing the device drivers.

Know Your Android Tools: What Is Fastboot & How Do You Use It?

Once again, type "Y" and press enter, which will open another installer for the drivers. Simply click "Next" and allow the drivers to install.

Know Your Android Tools: What Is Fastboot & How Do You Use It?

Once the installation is complete, select "Finish" and the installer will close and you are all done.

Mac OS X Installation

In the same vein as the Windows installer used above, scripts have been written for OS X that massively simplify the Fastboot installation process.

Follow the process in the above video and described here by Andrew to quickly install Fastboot and ADB on your Mac computer.

Linux Installation

By far the easiest installation process of them all. On many distros, including Kali Linux and BackTrack, you will only need to issue a single command from the terminal:

sudo apt-get install android-tools-fastboot android-tools-adb

Know Your Android Tools: What Is Fastboot & How Do You Use It?

If for some reason that does not work, you may need to manually add a repository to APT (advanced packaging tool) with the following command. Once that is complete, issue the first command again and it should install this time.

sudo add-apt-repository ppa:phablet-team/tools && sudo apt-get update

Note: If you are using a flavor of Linux that does not use APT, you will need to look up the installation procedure for your specific package manager, though it should be fairly similar.

Step 2: Setting Up Your Phone to Use Fastboot

Now it's time to boot your phone into "fastboot mode." On most models, you can enter fastboot mode by turning your device completely off and turning it back on by holding down the Power and Volume Down buttons simultaneously.

Know Your Android Tools: What Is Fastboot & How Do You Use It?

With your device in fastboot mode, connect it to your computer using your device's USB cable, then open up the command/terminal prompt on your computer and type the following.

fastboot devices

If fastboot is working properly, you will see your device listed here by its serial number.

Know Your Android Tools: What Is Fastboot & How Do You Use It?

If you do not see any devices listed, make sure that your device is actually in fastboot mode and that you are using a good USB cable (yes, this does make a difference).

Step 3: Basic Fastboot Commands

Now that we have fastboot up and running, let's see what we can do with it.

Unlock/Relock Your Bootloader

On Nexus devices, the following command is all that is required to unlock your bootloader and root your device.

fastboot oem unlock

However, on other devices, unlocking the bootloader alone will not be very helpful. You will need to use specific exploits to remove the radio secure flag completely. Be sure to do research on your specific device to know the exact unlocking/rooting procedure.

To reverse the above process and relock your device's bootloader, simply use the following command.

fastboot oem lock

NOTE: Be aware that unlocking the bootloader will wipe your device, so back up all your user data before doing this.

Flash a Custom Recovery

There are a number of custom recoveries that are available for most devices, the most popular of which are ClockworkMod and TWRP. Download a recovery for your device to your computer and make sure that it is an IMG file (it may need to be extracted, if it has a ZIP or other archive extension).

Open the command prompt, navigate to the folder where the recovery image is saved and issue the following commands:

fastboot erase recovery
fastboot flash recovery <recovery-file.img>

Know Your Android Tools: What Is Fastboot & How Do You Use It?

Flash a Custom ROM

Typically, once a custom recovery installed, most will use it to install ROMs, kernels, etc. However, it is possible to to do all of that with the fastboot, which can be useful, especially if you find yourself in a situation where your recovery partition is corrupt.

Download a compatible ROM to your computer. Open up the command prompt and navigate to the folder where you downloaded the file, then use the following:

fastboot erase system -w
fastboot erase boot

Know Your Android Tools: What Is Fastboot & How Do You Use It?

These commands will wipe your device's system, data, cache, and boot partitions before your install your new ROM. While there are times when a "dirty" flash is okay, doing this will help you to avoid issues when installing a new ROM. Now, enter the following command:

fastboot update <your-file.zip>

The zip is now installed—if your device does not automatically reboot, you can do it manually by issuing this command:

fastboot reboot

Flashing a Radio

Flashing a new cellular radio to your device can be dangerous. That said, a new radio can improve cellular reception, data speeds, and battery life. It is impossible to know which radio will work best for you without trying it out and observing the effects, as they will react different based off geography and general signal strength in your location.

Download a radio for your device to your computer and make sure that it is an IMG file (it may need to be extracted, if it has a ZIP or other archive extension).

Open the command prompt, navigate to the folder where the radio image is saved and issue the following command:

fastboot flash radio <radio-file.img>

When that command executes successfully, reboot the bootloader:

fastboot reboot-bootloader

Occasionally, device manufacturers will also release a "rcdata.img" file with a new radio. This file should also be flashed, via this command:

fastboot flash rcdata rcdata.img

Flashing a Kernel

Download a compatible kernel for your device to your computer. The kernel should be an IMG file. Open a command prompt, navigate to the folder where you saved the kernel and issue the following commands:

fastboot erase boot
fastboot flash boot <kernel-file.img>

Know Your Android Tools: What Is Fastboot & How Do You Use It?

Step 4: Advanced Fastboot Commands

Now that you've got the basics down, here are some fun advanced fastboot techniques that might come in handy.

Change Your Device's Splash Screen

Flashing a new splash screen (the image or GIF that displays as your device is booting up) is a surprisingly low-level task to perform on your Android device and, as such, requires full s-flag off status to work. If you don't know what this means, I would suggest just sticking with the default.

Download or create a splash screen image file. Open your command prompt and navigate to the folder where it is saved , then issue this command:

fastboot flash splash1 <splash-screen-file.img>

When you reboot your phone, you should now see your new splash screen.

Boot Your Phone with a Kernel or Recovery Image Without Flashing It

Ever feel like trying out a new kernel or a custom recovery, but you're not sure that you want to commit? Maybe you would like to test out several kernels back to back to evaluate their features and performance, or you need a specific recovery feature but know you will only need it once. Here is how to boot your device with a kernel or recovery without flashing it.

For kernels, open a command prompt, navigate to the folder containing the kernel (which must be an IMG file) you want to boot and type:

fastboot boot <kernel-file.img>

Know Your Android Tools: What Is Fastboot & How Do You Use It?

For custom recovery images, open a command prompt, navigate to the folder containing the recovery (which must be an IMG file) you want to boot and type:

fastboot boot <recovery-file.img>

Restore a Nandroid Backup

While unfortunately you cannot make a nandroid backup with fastboot, you can use this versatile tool to restore one, quickly and cleanly.

The nandroid backup must be stored on your computer (which is convenient anyway as it frees up space on your device) and it must be stored in the yaffs2 format (you can identify this format as a series of IMG files that correspond to the various backed up partitions, like data, system, and boot).

First, perform a system wipe:

fastboot erase system -w
fastboot erase boot

Next, flash each partition from your nandroid backup:

fastboot flash userdata data.img
fastboot flash system system.img
fastboot flash boot boot.img

As easy as that, your backup is restored and you can reboot your device.

Now that you have a better grasp on what fastboot is and what exactly it can do, you can dive into your Android device's partitions and flash with confidence.

That's about it for this introduction to fastboot. Is this something you'll be using the next time you hack your device? Or are you already familiar with fastboot and think we left something out? Let us know in the comments!

Fastboot

For the PC fast booting ability, see Instant-on.

Not to be confused with the Android recovery mode or the Samsung specific Fastboot alternative called Odin mode.

Fastboot is a protocol[1] and a tool of the same name. It is included with the Android SDK package used primarily to modify the flashfilesystem via a USB connection from host computer. It requires that the device be started in Fastboot mode. If the mode is enabled, it will accept a specific set of commands sent to it via USB using a command line.[2] Fastboot allows to boot from a custom recovery image. Fastboot does not require USB debugging to be enabled on the device.[3] Not all Android devices have fastboot enabled.[4] To use fastboot, a specific combination of keys must be held during boot.[5]

Android device manufacturers are allowed to choose if they want to implement fastboot or some other protocol.[6]

Keys pressed[edit]

The keys that have to be pressed for fastboot differ for various vendors.[7]

  • HTC and Xiaomi: Power and volume down
  • Sony: Power and volume up
  • Nexus: Power, volume up and volume down

On Samsung devices, Power, volume down and home has to be pressed for entering ODIN mode. This is a proprietary protocol and tool as an alternative to fastboot.[6]

Commands[edit]

Some of the most commonly used fastboot commands include:

  • flash – rewrites a partition with a binary image stored on the host computer.
  • flashing unlock/oem unlock *** – unlocks an OEM locked bootloader for flashing custom/unsigned ROMs. The *** is a device specific unlock key.
  • erase – erases a specific partition.
  • reboot – reboots the device into either the main operating system, the system recovery partition or back into its boot loader.
  • devices – displays a list of all devices (with the serial number) connected to the host computer.
  • format – formats a specific partition; the file system of the partition must be recognized by the device.

Implementations[edit]

The fastboot protocol has been implemented in the Little Kernel fork of Qualcomm[8][non-primary source needed] and in TianoCore EDK II.[9][10][non-primary source needed]

Fastboot is a mode of the Android bootloader called ABOOT.[11]
