How To Install ADB And Fastboot On Android Device And Use Your Phone/Tablet Like a PC

You may have heard and used ADB and Fastboot on a computer but in this article, I’m going to share with you a totally different ways to use these tools. Did you ever think you can use ADB and Fastboot without a PC? Well, actually, you can. ADB and Fastboot can be installed on another Android device and you can use it the same way as a computer.
ADB and Fastboot are very useful tools. They come in handy for various purposes. Via Fastboot you can flash almost everything. It might happen we don’t have access to a computer all the time but we always have our smartphone with us. So why not installing ADB and Fastboot on Android device? If you want to do it, keep reading below.

Requirements

  • A rooted Android phone or tablet.
  • OTG cable, but first make sure your device supports OTG.
  • A root browser like Root Explorer, ES file explorer. Both are free on Play Store.
  • Terminal emulator.

You can’t use ADB and Fastboot binary files for Linux on an Android device because those files are not compiled for ARM. However, thanks to Google there is ADB compiled for ARM. This file is already included in most of the newest Android devices.

Open your favorite file explorer and go to system/bin or system/xbin folder and search for ADB. If you can find this file there, there is no need to download it again.

Thanks to a developer named josteink we have also Fastboot binary compiled for ARM. This is not coming with your device natively so you will need to download it.
