Google Pixel 6A Firmware Android 15 Downgrade Guide

Learn how to safely downgrade your Google Pixel 6A firmware to Android 15 using fastboot factory images. This method helps fix IMEI, baseband, or network issues after recent updates.

Why Downgrade to Android 15?

Many Pixel 6A users report issues after updating to newer Android builds — including unstable network signals, battery drain, or IMEI corruption. Downgrading to the stable Android 15 release can restore performance, compatibility, and connectivity.

Before You Start: This process wipes your phone completely. Back up photos, contacts, and any important files first.

Requirements

Windows, macOS, or Linux PC
USB-C cable
Platform-Tools (ADB + Fastboot)
Official Pixel 6A Android 15 factory image
Battery charged above 50%

Step 1 — Enable Developer Options

Go to Settings → About Phone → Build Number and tap it 7 times.
Return to Settings → System → Developer Options.
Enable OEM Unlocking and USB Debugging.

Step 2 — Unlock the Bootloader

Bootloader unlocking is required for flashing firmware images.

adb reboot bootloader
fastboot flashing unlock

Confirm on the device screen using volume keys. The phone will factory-reset automatically.

Step 3 — Download Android 15 Factory Image

Download the official Android 15 factory image for Pixel 6A from Google’s firmware page.

Tip: Make sure the image name includes “bluejay” — that’s the Pixel 6A code name.

Step 4 — Extract and Flash the Firmware

Extract the downloaded ZIP to any folder on your PC.
Connect the Pixel 6A in Fastboot Mode (press Power + Volume Down together).
Open Command Prompt in the extracted folder and run:
```
flash-all.bat
```
Wait until the flashing process finishes and the phone reboots automatically.

Step 5 — Relock Bootloader (Optional)

If you prefer stock security, you can relock the bootloader after confirming that the phone works fine.

adb reboot bootloader
fastboot flashing lock

Troubleshooting

Device not detected: Re-install USB drivers or switch to another USB port.
Flash script fails: Run Command Prompt as Administrator or use manual flashing with each image.
Boot loop after downgrade: Perform a factory reset from recovery mode.

Important: Do not interrupt the flashing process or disconnect the cable while firmware is being installed. Doing so may permanently damage the device.

Follow each step carefully, use the correct firmware image, and never disconnect the phone mid-flash. Once complete, enjoy a fast, reliable, and fully functional Pixel 6A again!
