How to Downgrade Android 15 to Android 14

Downgrading from Android 15 to Android 14 is a way to roll back to a previous, often more stable or familiar version of the operating system on your phone. This process is more involved than a simple update and requires an unlocked bootloader, a PC, and the correct firmware files for your specific device. It is only officially supported on Google Pixel devices; other manufacturers typically do not allow downgrades. This guide walks you through the complete process, from preparation to troubleshooting, so you can safely return to Android 14.

What You’ll Need

A Google Pixel phone (or a device with an unlocked bootloader that supports manual flashing)
A PC or laptop running Windows, macOS, or Linux
A USB cable that supports data transfer (not just charging)
The Android SDK Platform Tools (includes ADB and Fastboot) installed on your PC
The official Android 14 factory image for your exact device model
Backup of all important data (the process wipes your phone)

Step-by-Step

Back up your data. Downgrading will wipe your phone completely. Use Google’s built-in backup (Settings > System > Backup) and also copy any local files (photos, documents) to your computer or cloud storage.
Unlock the bootloader. If you haven’t already, go to Settings > About phone and tap “Build number” seven times to enable Developer options. Then go to Settings > System > Developer options and enable “OEM unlocking.” Connect your phone to the PC, open a command prompt/terminal, and run adb reboot bootloader. Once in fastboot mode, run fastboot flashing unlock and confirm on the phone. This wipes your data, so do it before you need the data.
Download the correct factory image. Visit the official Google Developers page for factory images and download the Android 14 image that matches your device’s codename (e.g., Pixel 8 is “shiba”). Make sure it’s the full factory image, not an OTA update.
Extract the factory image. Unzip the downloaded file. Inside, you’ll find another zip file (e.g., shiba-tq3a.230805.001.zip). Extract that as well. You should see a folder containing files like flash-all.bat (Windows) or flash-all.sh (Mac/Linux), along with image files.
Boot your phone into fastboot mode. If your phone is on, run adb reboot bootloader. If it’s off, hold the power and volume-down buttons simultaneously until the fastboot screen appears.
Run the flash script. On Windows, double-click flash-all.bat. On Mac/Linux, open a terminal in that folder and run ./flash-all.sh. The script will flash the Android 14 firmware and automatically reboot your phone. Wait until the process finishes (it may take several minutes).
Set up your phone. After the reboot, you’ll see the Android 14 setup screen. Follow the prompts to set up your device. Your data is gone, so you’ll need to restore from your backup.

Common Mistakes

Using the wrong factory image. Downloading the image for a different device model will fail or brick your phone. Always verify your device’s codename in Settings > About phone.
Skipping the bootloader unlock. If you don’t unlock the bootloader first, the flash will fail with an error.
Not backing up data. The process wipes everything. If you skip this, you’ll lose photos, messages, and app data permanently.
Using a faulty USB cable. A cable that only charges can cause the flash to get stuck or fail. Use a high-quality data cable.
Interrupting the flash. Disconnecting the phone or closing the terminal during flashing can brick the device. Let it finish.

Tips

Keep your phone charged above 50% before starting to avoid shutdown during flashing.
If you’re not comfortable with command-line tools, consider using the Android Flash Tool (a web-based tool) for a more guided experience, but it still requires an unlocked bootloader.
After downgrading, your phone may show a notification about a system update to Android 15. You can disable automatic updates temporarily in Developer options to prevent re-upgrading.
Use the exact version of Platform Tools from the official Google site to avoid compatibility issues.

Troubleshooting

“fastboot: command not found” – This means Platform Tools are not installed or not in your PATH. Install them and add the folder to your system’s PATH, or run the command from that folder.
Flash fails with “FAILED (remote: not allowed)” – Your bootloader is likely still locked. Unlock it first (step 2).
Phone gets stuck in a boot loop after flashing – This usually happens if the firmware is corrupted or mismatched. Re-download the factory image and re-flash it. If that doesn’t work, try flashing to the latest Android 15 first, then downgrade again.
“Device is not recognized” in fastboot – Install the proper USB drivers for your Pixel on Windows. On Mac/Linux, ensure you have the correct permissions (try running as root).
The flash script stops at “waiting for device” – Make sure your phone is in fastboot mode (not ADB mode) and the USB connection is solid. Try a different USB port.

Frequently Asked Questions

Q: Will downgrading void my warranty?
A: Unlocking the bootloader and flashing a factory image may void your warranty, depending on the manufacturer. Google’s policy is that unlocking the bootloader is allowed, but any damage caused by flashing is not covered.

Q: Can I downgrade without a PC?
A: No, the standard method requires a computer to run fastboot commands. There is no official way to downgrade directly on the phone.

Q: Will I lose all my data?
A: Yes, the process wipes the device completely. Always back up before starting.

Q: Can I downgrade a Samsung or Xiaomi phone?
A: Most manufacturers do not allow downgrades. If your bootloader is unlocked and the firmware is available, it may be possible, but it’s risky and not officially supported.

Q: What if I want to go back to Android 15 after downgrading?
A: You can simply install the Android 15 OTA update or re-flash the Android 15 factory image using the same steps.

Q: Is there a risk of bricking my phone?
A: Yes, if you flash the wrong firmware or interrupt the process. Follow the steps carefully, and you should be fine.
