There are some situations where you’ll discover that you can’t download updates on your phone or you can’t install updates you’ve downloaded. This is often because your manufacturer isn’t providing further updates for your phone.
Generally, manufacturers specify the number of updates they allow for a device. When the device reaches its specified number of updates, they stop providing updates. In these cases, you can sideload the updates to your smartphone using ADB sideload method.
If you are looking to find out what ADB sideload is and how to apply update from ADB, you will find this guide helpful. In this article, you will get to know everything about the ADB feature.
What is ADB?
ADB is short for Android Debug Bridge. It is a command-line tool that allows you to communicate with any Android device connected to your PC.
With this tool, you can transfer data and gain control over a device’s filesystems. In addition, developers use this tool for debugging and deploying codes on Android devices as long as they can establish a host-target connection using a USB connection.
Due to the functionality of this tool, many people apply update from ADB when they are unable to receive regular OTA (Over-the-air updates).
People with knowledge of ADB and the Android operating system can usually enable features that influence user experience. For example, aside from debugging apps, they can also install third-party apps that aren’t on Play Store.
With all of that being said, you should know that ADB is a client-server program that consists of three components;
- The Clients: The Clients are the computer and Android devices involved in the process.
- Daemon or The Client Service: Daemon is a Client Service that needs to be present on the computer and Android device to allow communication through commands.
- The Server: The Server is the software that manages all the communications between the “Clients” and “Daemon.”
What is ADB Sideload?
Before you know what ADB sideload is, you need first to understand what Sideloading means. Sideloading is a term that’s similar in functionality to uploading / downloading. It involves the process of installing apps and software from an external source.
This system is what people use to apply update from ADB.
ADB sideload itself refers to installing or sideloading apps and software using ADB. It involves the transfer of data between an Android device and a PC.
Yes, it is the same. However, there are some situations where you will need to do something different for you to be able to apply update from ADB on a Samsung device.
Sometimes, an ADB connection requires an official Samsung cable to work. For example, you will need an official Samsung cable to establish a connection between the Samsung device and your PC.
- You can use ADB with any command-line interface such as CMD, Mac OS, or Linux Command-Line.
- You can transfer files outside the Android User Interface using push or pull.
- ADB allows you to push updates to your Android when you cannot receive regular OTA (Over-the-air updates).
- If your phone has issues, you can pull logs, system information, memory usage, and information on Installed apps to pinpoint where the issues originate.
- ADB allows you to install Third-Party Android apps not available on Google Play Store.
- You can use the ADB also to remove pre-installed apps.
- ADB provides a way of removing Bloatware without the root.
- You may not be able to access some commands on the ADB system.
- Before running commands, you need first to install ADB on your computer. You cannot execute commands if you don’t have ADB.
You need to do some things before you apply update using ADB. These things include:
- Charging your device above 75% to ensure that your device won’t run out of battery during the update process.
- Get a USB cable.
- Activate developer mode and enable USB debugging on your device.
- Install the required device drivers on your PC
- Download all the required files, which include zip files.
- Download and install Android SDK on your PC.
- Install the ADB driver on your PC
- Before you do any other thing, you need to make sure that you always back up your phone before applying any update. One way to do this is by copying all the data on your device into your computer. For example, make sure you copy every picture, video, and contact on your phone.
- If you want to apply update from ADB onto a device, you need to make sure you disconnect all other devices connected to the PC.
- As mentioned earlier, you need to ensure that you always charge your device before you apply update from ADB. This will help prevent interruptions that can occur due to low battery.
- Start the update procedure slowly so that the device doesn’t begin to hand when the procedure becomes more intense.
- Ensure that you use the latest tools when you want to apply update from ADB.
- You can disable all wireless connections by turning ON airplane mode.
How to Apply Updates from ADB – Step by Step
You can apply updates from ADB, just like the option on the Android system recovery screen implies. Applying the update can be done by connecting your Android device to your computer and then using a command line to send and install the update onto your phone. Below is a step-by-step guide to applying an update from ADB.
- STEP 1: Charge your phone battery and make sure that it is fully charged (or at least more than 60%) before unplugging from the power source.
- STEP 2: Enable debugging via USB.
- STEP 3: Install device drivers on a computer.
- STEP 4: Download the required file (file.zip). Be sure to download files from trusted sources only, so as not to harm the computer (it is recommended that you use the services of the portals of the manufacturer of the smartphone).
- STEP 5: Download Android SDK on your computer.
- STEP 6: Download the Platform-Tools package on your computer (This is a special tool necessary to install custom recovery and root the phone).
- STEP 7: Unzip the zip. File.
- STEP 8: Connect your android phone to the computer with a USB cable and ensure that it is detected by the computer.
- STEP 9: Open the unzipped folder and hold the “shift” key, then right-click your mouse.
- STEP 10: Choose “open command window here”. A command window will show up next.
- STEP 11: Enter the command “ADB devices”. This helps to check if ADB is properly installed and compatible with your computer. Getting a serial number followed by “device”, means your ADB is working correctly.
- STEP 12: Now, move the update.zip file to the Platform-tools folder.
- STEP 13: Boot your smartphone into recovery mode. Turn OFF the phone, then hold the volume control key for a few seconds. Use the same keys to choose the “apply update from ADB” option and then click on “power”.
- STEP 14: Go back to the computer and type “ADB sideload firmware file name” in the command prompt window and then the zip. file will be sent to your android. Your android will open the file and verify it. The zip. file will be sideloaded and written in your android. The process will take a long time. Do not stop the process halfway, as the file will not open after and you will have to repeat the steps. When it is completed, you will see “Install from ADB complete” on the screen.
Note: If “error: closed” is displayed, it means that the sideload was not activated on your android.
If “error: device not found” is displayed, it means that the PC did not see android. To fix the problem, change the kernel, recovery, reboot the device, and start all over again.
How To Update An ADB Installation To The Latest Version
There are several methods to update an ADB installation to the latest version. One of the simplest methods is to get the latest platform tools and combine them with a bash alias for convenience.
Doing this will enable you to create a new ‘Android’ directory at the root of your home directory. Then, you can change the paths using the example below if you prefer a different location.
mkdir ~/Android && cd ~/Android
After doing that, download and extract the platform-tools from Google:
Full code line:
wget https://dl.google.com/android/repository/platform-tools_r33.0.3-linux.zip && unzip platform-tools-latest-linux.zip
By now, the latest ADB and other tools will be able to run directly from the newly extracted ‘platform-tools’ directory. It would be best if you uninstalled obsolete packages to avoid conflicts.
Overall, all you need to do to update your ADB is to ‘cd’ the Android directory and repeat the download and extract step again. After that, you can use the ADB version to check the version you currently have installed.
