ADB Basic Commands and Setup Tutorial

Recently, I was asked to flash a custom ROM to several Android devices that Samsung seems to forget to update. These devices include:

1. Galaxy Tab 10.1 (GT-P7500) – Upgraded from Android 3.2 Honeycomb to 4.2 Jelly Bean

2. Galaxy Tab 8.9 (GT-P7300) – Upgraded from Android 3.2 Honeycomb to 4.2 Jelly Bean

3. Galaxy Mini (GT-S5570) – Upgraded from Android 2.3 Froyo to 4.1 Jelly Bean

I was delighted seeing these old devices run with the Jelly Bean OS.

Please note that I actually have no plans of posting how to root and upgrade certain devices here in our blog. (But if many of you insists, I may change my mind haha!)

This is because there are already a lots of resources on other sites, especially in the XDA-Developers forum.

In my experience, rooting and flashing a custom ROM to your device may take a lot of trial and error. One blog post may not work for you, so you have to look on other blog post or forums and maybe combine their instructions or installation files for your device to work.

So, this tutorial will just cover some ADB commands that I learned and can be useful when doing such tasks. This list can be your reference too!

1.0 What is ADB?

First off, for those who have no idea what ADB is, ADB stands for Android Debug Bridge. Basically, it is a command line interface that lets you communicate from PC to your Android device or emulator.

On windows, it is an .exe file where you can execute some commands (see section 4.0 below) with the help of command prompt (cmd.exe).

2.0 Where can I get ADB?

I used the ADB from the Android ADT Bundle we installed, yes it is with the Android developmenet environment files. I actually wrote a post regarding its installation. You can find it in the path: YourADT_Folder > sdk > platform-tools > adb.exe

3.0 How To Run The ADB?

Easy, just follow the steps below:

3.1. Open your command prompt.

On windows, you can type on the search box “cmd.exe” and then press enter. It will pop up a really cool black window.

3.2 Find your adb.exe

Go to your ADT folder > sdk > platform-tools

Copy the path, go back to the black window, right click then paste it there. After pasting, press enter. See screenshots below:

After pasting, press you enter key. Now you’re insde the adb directory. Enjoy the ADB commands below. :D

4.0 ADB Basic Commands

4.1 Make sure ADB is working by typing the “adb” command (see the yellow underline below). The output will look like this:

4.2 Know what Android devices were attached on your computer by typing the “adb devices” command.

4.2.1 If it can’t connect to your device, first, you have to do an adb kill-server command

4.2.2 And then, do an adb start-server command, and re-execute adb devices

4.3 Begin a shell connection with your Android device by typing the “adb shell” command. More about shell here.

4.3.1 Know what files and directories are in your Android device by typing the “ls” command

4.3.2 If you think you’re done with the shell connection, you can exit it by typing the “exit” command, and now you’re out of the shell mode.

adb shell exit command

4.3.3 Change directories by using the “cd” command. Sample use:

cd /sdcard/my_folder

4.3.4 If you want to remove a file from your device, here’s the “rm” command. Sample use:

4.3.5 copy file from one directory to another with the “cp” command. Sample use:

cp /sdcard/my_old_folder/my_text_file.txt /sdcard/my_new_folder/my_text_file.txt
