Stuck on Verifying Update… and Just Blank in Terminal: No Updates, Nothing — How to Fix It

We understand how frustrating it can be when your device hangs on “verifying update…” and your terminal shows nothing—no progress, no updates, no error messages. This issue is especially common among Pixel 2 users trying to update their firmware, flash custom ROMs, or install Magisk modules. In this comprehensive guide, we’ll walk you through every possible cause and solution, ensuring you can resolve this problem and get your device back on track.

Understanding the Problem

When your Pixel 2 gets stuck on “verifying update…” or the terminal goes blank, it usually means the update process is halted due to a communication issue between your device and the computer, a corrupted download, or a problem with the flashing environment. This can happen during OTA updates, manual firmware flashing, or when installing custom modules.

Common Symptoms

• Device displays “verifying update…” indefinitely.
• Terminal or command prompt goes blank with no output.
• No error messages are shown.
• Device may reboot or become unresponsive.
• Attempts to retry the update fail repeatedly.

Primary Causes of the Issue

Several factors can cause your Pixel 2 to get stuck during the update verification process. Let’s break down the most common causes:

1. Corrupted or Incomplete Update Files

If the firmware or update package you downloaded is corrupted or incomplete, the verification process will fail silently, causing the device to hang.

2. USB Connection Problems

A faulty or loose USB cable, or a problematic USB port, can interrupt the communication between your device and the computer, leading to verification failures.

3. Driver or Software Issues

Missing or outdated USB drivers, or problems with the flashing software (such as Fastboot or ADB), can prevent the update from proceeding.

4. Device-Specific Issues

Pixel 2 devices may have unique quirks, such as bootloader restrictions or specific firmware requirements, that can cause update hangs if not properly addressed.

5. Insufficient Storage or Battery

If your device’s storage is nearly full or the battery is too low, the update process may stall or fail.

Step-by-Step Solutions

Now that we’ve identified the potential causes, let’s dive into the solutions. We recommend following these steps in order, as they range from simple checks to more advanced troubleshooting.

1. Verify and Re-download the Update Package

Before attempting any technical fixes, ensure your update package is intact:

• Delete the current update file.
• Re-download it from the official source (such as the Google Factory Images page for Pixel devices).
• Verify the file’s integrity using checksums if provided.

2. Check and Secure Your USB Connection

• Use the original USB cable that came with your Pixel 2.
• Try different USB ports on your computer.
• Avoid using USB hubs or extension cables.
• Ensure the cable is firmly connected at both ends.

3. Update USB Drivers and Flashing Tools

• On Windows, download and install the latest Google USB drivers.
• Ensure you have the latest versions of Fastboot and ADB tools.
• On Linux or macOS, make sure your system recognizes the device when booted into bootloader mode.

4. Boot Your Pixel 2 into Bootloader Mode

• Power off your device.
• Press and hold the Volume Down and Power buttons simultaneously until the bootloader screen appears.
• Connect your device to the computer.
• Open a terminal or command prompt and type:

  fastboot devices
  

  If your device is listed, the connection is working.

5. Wipe Cache and Try Again

Sometimes, cached data can interfere with the update process:

• In bootloader mode, use the volume buttons to navigate to Recovery Mode and press Power.
• Once in Recovery, select Wipe cache partition.
• Reboot and attempt the update again.

6. Perform a Factory Reset (Last Resort)

If all else fails, a factory reset may be necessary:

• Boot into Recovery Mode as described above.
• Select Wipe data/factory reset.
• After the reset, try the update process once more.

7. Check for Known Issues and Workarounds

Search online forums and communities (such as the official Pixel User Community or XDA Developers) for any known issues specific to your firmware version or update package. Sometimes, other users have found unique workarounds.

8. Use Alternative Flashing Methods

If the standard update process fails, consider using an alternative method:

• Flash the firmware manually using Fastboot commands.
• Use a custom recovery like TWRP if your device is rooted.
• For Magisk modules, ensure you’re using the latest version compatible with your Android version.

9. Ensure Sufficient Battery and Storage

• Charge your device to at least 50% before attempting an update.
• Free up storage space by removing unnecessary files or apps.

10. Seek Professional Help

If none of the above steps resolve the issue, it may be time to contact Google Support or visit an authorized repair center, especially if your device is still under warranty.

Preventing Future Update Issues

To avoid running into similar problems in the future, consider the following best practices:

1. Always Use Official Sources

Download firmware and updates only from official sources, such as the Google Developer site or your device manufacturer’s support page.

2. Keep Your Tools Updated

Regularly update your USB drivers, Fastboot, and ADB tools to ensure compatibility with the latest devices and firmware.

3. Maintain Your Device

Periodically clear your device’s cache and ensure you have ample storage space for updates.

4. Stay Informed

Join online communities and forums related to your device. Staying informed about known issues and solutions can save you time and frustration.
