Unlocking the bootloader of your Android device is often the initial step in exploring the full potential of custom development. This process allows you to flash custom ROMs, recoveries, and gain administrative privileges through root access. Traditionally, unlocking the bootloader requires a PC, the download of SDK Platform Tools, and the installation of Fastboot Drivers. But what if you don’t have access to a PC or find these steps too complex? In this guide, we’ll show you how to unlock the bootloader on your Android device without the need for a PC.

Why Unlock the Bootloader?

Unlocking the bootloader is a critical prerequisite for various advanced customizations, but it comes with a few important considerations. Firstly, this process will erase all data on your device and may void its warranty. Therefore, it’s essential to back up your important data before proceeding.

What You Need

To unlock your device’s bootloader without a PC, you’ll need a second Android phone, a USB cable, and a USB OTG adapter. The primary device is the one you intend to unlock, while the secondary device facilitates the process. If you’re a Xiaomi, Redmi, or Poco user, please note that the process differs for you, and you should refer to a separate guide.

Here are the steps to unlock the bootloader without a PC:

  1. Connect the USB OTG Adapter: Plug the USB OTG adapter into your secondary device.
  2. Plug in the USB Cable: Connect the Type A end of the USB cable to the OTG adapter.
  3. Connect to Your Primary Device: Plug the Type C end of the USB cable into your primary device.
  4. Download the Bugjaeger App: Install the Bugjaeger app on your secondary device.
  5. Launch Bugjaeger: After installation, open the app. You’ll receive a prompt that says, “Open Bugjaeger to handle <device name>.” Tap OK.
  6. List Devices: In the Commands section of the app, tap on “List Devices.” Your primary device should be listed at the bottom. If not, try unplugging and replugging the USB cable/OTG adapter until you get the prompt with the device name.
  7. Reboot to Fastboot Mode: Once your primary device is recognized, tap on the “Reboot Bootloader” icon. This action will boot your primary device into Fastboot Mode.
  8. Access the Command Window: Tap on the shell icon at the bottom right of the app. This will open the Command window.
  9. Enter the Fastboot Command: In the Command window, type the following command and press Enter:
    • fastboot devices
      • Ensure that you receive a serial ID. If not, repeat the USB/OTG connection process until the ID appears.
  10. Unlock the Bootloader: Finally, type the following command to unlock the bootloader and press Enter:
    • fastboot flashing unlock
  11. Your device will reboot and boot into the operating system.
