ADB (adb) stands for Andriod Debug Bridge. As the name suggests, it is a handy tool that helps you communicate with the device to a great extent. The tool is also helpful in actions like installing or debugging any app.

What Is ADB Sideload?

As we spoke about what is ADB, we must also talk about ADB Sideload. So, what is ADB Sideload?

ADB sideload is a new feature that was added to AOSP recovery in Jelly Bean. As of version 2.3, TWRP now supports ADB sideload mode. ADB sideload is a different ADB mode that you can use to push and install a zip using one command from your computer. Most likely ADB sideload won’t be very useful for your average recovery user, but ADB sideload can be a huge time-saver for a ROM developer.

How Can I Use ADB Sideload?

Having an idea of what ADB Sideload is if you are now wondering how can you use ADB sideload, here is a guide for you.

1. First, install a recovery in your device that supports the sideload like TWRP versions 2.3 or higher.
2. Have the latest ADB Binaries installed on your computer. You can get the latest ADB Binary from Platform-tools from the Android SDK.
3. Version 1.0.29 or higher is required.
4. Once you’re done with this, turn the device’s settings into “ADB Sideload” mode.
5. If you’re using TWRP, you can do this from “Advanced > ADB Sideload.”
6. Now, from the Command line, type adb sideload /path/to/rom.zip

And, you’re good to go!

Notes:

For TWRP Versions Lower Than 2.8.2.0:

Regardless of the existing storage location you have chosen on your device on the mount page, the file will be copied there. Also, remember that the file will be placed in the root storage and named ‘sideload.zip’.

The file will also overwrite or delete any other files by the same name.

After the file is copied to your device, it will immediately begin to install itself. When the installation is complete, a button to reboot the system will be displayed, allowing you to do so and test your package.

For TWRP Versions Higher Than 2.8.2.0:

TWRP Versions higher than those mentioned above will stream the zip file from your PC without downloading it to your device.

Definitely avoid using sideload if you wish to download the file to your device.

How To Enable ADB Over USB TWRP?

We are pretty sure that you will be aware but, here it is: TWRP stands for TeamWin Recovery Project.

It is also a Canadian rock band that was formed in 2007 known as the Tupper Ware Remix Party (but we don’t need to talk about that here.)

Now, let’s talk about how to enable ADB Over USB TWRP.

While trying to enable ADB over USB TWRP, make sure you have the following conditions met:

1. You have stock recovery and a rooted phone
2. you have custom recovery.

The Changed Files will be:

1. /system/build.prop
2. /data/property/persist.sys.usb.config
3. /data/misc/adb/adb_keys

The process is essentially 2 steps. But, the catch is that there are little steps in between you have to follow and keep in mind.

The first step is to enable USB debugging. You can do that by: Settings > Developer Options >USB Debugging ON.

1. Now, connect your android device to your PC.
2. Open cmd on the computer and go to program-tools/
3. Type and enter: adb devices. This checks if your device has been connected successfully in recovery mode.
4. Type this command: adb shell mount data and adb shell mount system
5. Now use the adb pull/data/property/persists.sys.usb.config/your directory to get the persist.sys.usb.config file.
6. Now open the text editor that you use/have been using and edit it to mtp,adb.
7. Save it.
8. Now it’s time to push the file back to the device again. Use this command to do so: adb push/your-directory/persist.sys.usb.config/data/property
9. Next, go to the build.prop file: adb pull/system/build.prop/your-directory.
10. Add these commands:
    1. persist.service.adb.enable=1
    2. persist.service.debuggable=1
    3. persist.sys.usb.config=mtp,adb
11. It’s time now to push back the build.propback to the device. You can do that by using the command: adb push/your-dir/build.prop/system

The second step is to get RSA Verification.

Phewwww finally we’re done!

Why Does ADB not Recognize My Device In Recovery Mode?

If ADB cannot recognize your device in recovery mode, there can be a number of reasons for that to happen.

One reason could be that your device might not have been found in the first place. 

But if it is and your adb is still not recognizing your device, you should install “Google USB Driver”. This should help you in this case.

Below is the step description:

Google USB Driver > Device Manager > Device (right click) > Update Drive’s Software > Browse My Computer > Let me Pick > Android Device > Android ADB Interface
