Android fastbootSolved

Hey @yuudai! Fastboot is basically a protocol that lets you interact with your Android device at a low level. It’s used to communicate with the bootloader, which is the software that controls the startup process of your device. Fastboot uses commands to flash new firmware, install custom ROMs, and make other significant changes to your device’s software. It operates outside of the regular Android system, so you’re working directly with the core components of the device. 

Thanks for the explanation, @ezekiel. Is it safe to use Fastboot? 

Using Fastboot can be safe if you know what you’re doing. However, it’s important to be cautious because flashing the wrong files or improperly using Fastboot can potentially brick your device. Always make sure you have the correct files and follow the instructions carefully. 

Fair enough. So, how do you enable and use Fastboot? 

Hey @yuudai, 

First, you need to enable USB Debugging on your phone. Just go to Settings, find About phone, and then tap on the Build number seven times. This unlocks Developer Options. After that, go back to Settings > System (or directly Developer Options, depending on your device) and switch on USB Debugging. 

Next, you’ll want to get ADB and Fastboot ready on your computer. You can download the Android SDK Platform Tools from the official Android Developer website. Once you’ve got that, unzip the files into a folder where you can easily find them. 

To get your phone into Fastboot mode, you’ve got two options: 

1. Using ADB: 
   • Connect your phone to the computer with a USB cable. 
   • Open the command prompt (Windows) or terminal (Mac/Linux) and navigate to where you unpacked the Platform Tools. 
   • Type adb reboot bootloader and press Enter. Your phone should reboot into Fastboot mode. 
2. Using Buttons: 
   • Power off your phone. 
   • Hold down the Power and Volume Down buttons together until the phone boots into Fastboot mode. (This button combo might be different depending on your phone model.) 

Once you’re in Fastboot mode, you can start using Fastboot commands. For example, you can check if your computer recognizes your device by typing ‘fastboot devices’ in the command prompt or terminal. If your device shows up, you’re good to go! 

Once you’re done, you can restart your phone by typing ‘fastboot reboot’ in the terminal or command prompt 

Hello, 
I followed every step correctly, but when I type adb reboot bootloader, I am getting an error. 

Could you let me know if you are using Mac or Linux? On these systems, every ADB and Fastboot command must be preceded by ./. So, where you type adb on Windows, you should type ./adb on Mac and Linux. Similarly, for Fastboot, use ./fastboot instead of fastboot. 

Yes, I was using a Mac. It works fine now. Thank you!
