When it comes to managing your Android device, applying updates from ADB is a powerful method to install system updates directly. Whether you’re locked out of your device, unable to access normal update methods, or just want a manual alternative, ADB update method offers a solution. 

In this detailed guide, we’ll explore all the methods to apply updates from ADB, including using ADB sideload, the ADB command to update, and other related techniques for a manual Android update ADB process.

What is ADB and Why Use It for Updates?

ADB (Android Debug Bridge) is a command-line tool that allows communication between your Android device and a computer. ADB enables users to interact with their device via commands for debugging, development, and system management tasks, including updates.

Apply updates from ADB is particularly useful when your device cannot access the regular update methods due to issues such as boot loops, locked bootloaders, or other system errors. Let’s break down the best ways to apply update from ADB, starting with the different methods you can use.

Prerequisites for Applying Updates via ADB

Before we get into the methods, ensure you meet the following requirements:

Install ADB on Your Computer: ADB tools need to be installed on your PC or Mac. You can get the official platform-tools from the Android developer website.

USB Debugging Enabled: Go to Settings > About phone > Tap “Build number” 7 times to unlock Developer Options. Then, enable USB Debugging in Settings > Developer options.

USB Cable: Use a working USB cable to connect your Android device to the computer.

OTA Update File: You’ll need the appropriate OTA update file (often a ZIP file) compatible with your device. Make sure to download this from an official source or your device’s support page.

Bootloader Unlocked (for some methods): While not necessary for all cases, some methods might require you to have an unlocked bootloader. Ensure that you know the implications of unlocking your bootloader, as it could void your warranty.

Method 1: Apply Updates from ADB via ADB Sideload Update

The Apply Updates from ADB method is the most popular and widely used process for applying updates from ADB. This method is particularly useful when you are unable to update your device through the standard settings menu. Here’s how to do it:

Step 1: Reboot Your Device into Recovery Mode

1. Connect your Android device to the computer.
2. Open a command prompt or terminal window and use the command to reboot your device into recovery mode.
3. Your device will boot into recovery mode. Use the volume keys to navigate and select the “Apply updates from ADB” option in recovery.

Step 2: Apply the ADB Sideload Update

1. Once you’re in recovery, the Apply updates from ADB option will allow you to sideload the update. On your computer, use the command to push the update file to your device:
2. The update will begin, and the progress will be displayed in the terminal window. This process can take several minutes depending on the size of the update.

Step 3: Reboot the System

1. After the update completes successfully, select Reboot system now from the recovery menu.
2. Your device will restart with the new update applied.

This method is fast, effective, and often the go-to method when other solutions fail.

Method 2: Apply Update from ADB via ADB Push and Flash via Fastboot

If your device isn’t responding to the sideload update, you can use a combination of ADB commands and Fastboot to push the update to your device. This method is commonly used when the device is bricked or has issues accessing recovery.

Step 1: Use ADB to Push the Update to Your Device

1. First, you need to push the OTA update file to the device’s internal storage. You can use the adb push command to do this.
2. The update file will be transferred to the device’s internal storage in the /sdcard/ directory.

Step 2: Reboot into Fastboot Mode

1. Once the file is transferred, you need to reboot your device into Fastboot mode. This can be done by entering the command:
2. Your device will reboot into the bootloader or Fastboot mode.

Step 3: Flash the Update Using Fastboot

1. From Fastboot mode, use the fastboot flash command to flash the update.
2. The system will update, and your device will reboot once the process is completed.

This method is effective when you’re dealing with devices that cannot boot into recovery but can still enter Fastboot mode.

Method 3: Apply Updates from ADB with Custom Recovery (TWRP)

Custom recoveries like TWRP offer more flexibility when dealing with updates. If you’re using a custom recovery, the process is slightly different.

Step 1: Boot into TWRP Recovery

1. Connect your device to your computer and issue the following command to reboot into TWRP.
2. If you have TWRP installed, it will boot into the custom recovery mode.

Step 2: Use TWRP’s ADB Sideload

1. In TWRP recovery, choose Advanced and select ADB Sideload.
2. On your computer, run the command.
3. TWRP will apply the update file, and once it’s done, it will automatically prompt you to reboot.

Method 4: Manual Android Update via ADB

The manual Android update ADB method can be used when no traditional update is available or if your device has an issue. It involves using ADB commands to initiate a system update manually.

Step 1: Get the Update File

You need to download the OTA update file from an official source (device manufacturer or support page). Ensure that it is compatible with your device and Android version.

Step 2: Push the Update File to Your Device

1. Connect your device to the computer, and open the terminal or command prompt.
2. Push the update ZIP file to the device.
3. Once the file is transferred, navigate to recovery mode.

Step 3: Install the Update

1. In recovery mode, choose Apply updates from ADB and run the ADB sideload command to start the update process.

Troubleshooting Common Issues

• Ensure USB drivers are properly installed. Try different USB cables or ports.
• Check for corrupted update files. Ensure the update is for the correct model.
• If you encounter a bootloop after an update, try performing a factory reset from recovery.
