Updating the operating system on smartphones Google Pixel often brings long-awaited features and security patches, but the process does not always go smoothly. Flagship owners may encounter critical errors, unstable battery performance, or incompatibility of key applications after installing the new version. Android. In such situations, the only correct solution is to return to a stable, proven version of the firmware, which requires care and adherence to technical nuances.
The process of system downgrade (rollback) on Pixel devices is technically more complex than a regular update and carries the risk of losing all user data. Unlike iOS, where rollback is possible only during the signing period of certificates, the Android ecosystem allows for more flexible management of software versions, but requires manual downloading of images and the use of specialized software. You will have to work with the bootloader and memory partitions, so understanding the structure of the process is necessary even before you begin active actions.
In this guide, we will examine in detail the preparatory stage, methods of resetting the firmware through official Google tools and manually installing images via Fastboot. We will pay special attention to data security issues, since downgrading Android on Pixel is impossible without completely formatting the userdata partitionwhich means the loss of photos, contacts and settings. Following the instructions will help minimize risks and return the device to the previous version of the OS.
Risk assessment and preparing the device for downgrade
Before starting any manipulations with system partitions, you must realize that rolling back the Android version is a destructive operation. The security architecture Android is built in such a way that when the firmware version is downgraded, old data formats may become unreadable for the new (actually old) system, which leads to cyclic reboots or complete inoperability of the interface. That is why the system forcibly requires a complete reset, which cannot be ignored even if you have root access.
The most important step is to create a full backup. A standard Google cloud backup may not be enough to restore all settings and application data, especially if you use Two-Factor Authentication (two-factor authentication) in banks or instant messengers. Make sure you have access to the phone number or backup codes, as resetting the device will invalidate all tokens.
⚠️ Note: The flashing process only voids the warranty if hardware components are damaged due to incorrect actions, but a soft reset is a standard feature. However, if the bootloader or partitions are damaged in the process, the device may become bricked.
It is also critical to check the model of your device. Firmware for Pixel 6 will not be suitable for Pixel 6 Pro or Pixel 6a, despite the similarity of names. Using the wrong image may result in fatal radio or touchscreen errors. Always check the code name of the device (for example, oriole, raven, bluejay) with the name of the firmware file.
Required tools and software
To successfully complete the procedure, you will need not only the smartphone itself, but also a properly configured workplace. The main tool will be a utility Android Flash Toolthat works directly in the Google Chrome or Microsoft Edge browser based on Chromium. This is an official solution from Google that automates most complex processes, reducing the risk of human error when entering commands.
The USB-C cable you use plays a key role. Cheap charging cables often do not support high data transfer speeds or have poor connections, which can cause the system image to be interrupted mid-process. It is recommended to use the original cable included in the kit or a certified accessory with support for USB 3.0 and higher, if your PC has the appropriate ports.
The list of required software includes:
- 🔗 Official Google USB Driver (automatically installed via Flash Tool or SDK Manager).
- 🌐 Browser Chrome or Edge with JavaScript enabled and access to USB devices.
- 📂 Archive with a Factory Image for your specific model and target version of Android.
- 🔌 Stable Internet connection for initial communication with Google servers.
Use the USB port built directly into computer motherboard (the back panel of the PC), avoiding the front ports of the case or USB hubs to avoid power surges and lost data packets.
Finding and downloading the correct firmware version
You can find the correct system version on the official Google support page for Pixel devices. There are full images (Full Factory Images) for each device. It is important not to confuse OTA updates (which are intended to update the current system) and full images required for a clean installation or rollback. We need complete images, which usually have the word in the name factory.
When choosing a version, pay attention to the release date and build number. For example, if you want to downgrade from Android 14 to Android 13, you'll need to find the latest stable build of Android 13 (often labeled as QP1A or TQ3A depending on the quarter). The use of beta versions or developer images for rollback is not recommended, as they may contain unstable code.
Below is a table of correspondence between device code names and series for orientation in the files:
| Device model | Code name | Type processor | Year of release |
|---|---|---|---|
| Pixel 8 | shiba |
Google Tensor G3 | 2023 |
| Pixel 7 Pro | cheetah |
Google Tensor G2 | 2022 |
| Pixel 6a | bluejay |
Google Tensor | 2022 |
| Pixel 5 | redfin |
Snapdragon 765G | 2020 |
After downloading the archive, it must be unpacked. Inside you will find scripts for Windows (flash-all.bat) or Linux/Mac (flash-all.sh), as well as a set of image files (.img). Do not delete or rename these files, as the script relies on their exact names to correctly write to memory sections.
Instructions for rolling back through the Android Flash Tool
The safest and recommended way is to use the Android Flash Tool web interface. This method does not require manual installation of additional drivers (the browser will ask for permission to connect) and minimizes the risk of errors. To get started, go to the official website of the tool and connect your phone in USB debugging mode.
Enable developer mode on your Pixel by going to Settings → About phone and quickly pressing 7 times on Build number. Then in the menu System → For developers activate USB debugging i Debugging via Wi-Fi (optional). Connect the device to the PC and confirm the debugging request on the smartphone screen.
☑️ Check before flashing
The tool interface will show the connected device and the current software version. You need to select the "Change version" or "Install new build" option. In the list of available versions, select the one you want to roll back to. If the required version is not in the drop-down list, select the option to download another image and specify the path to the previously downloaded file.
⚠️ Attention: In the Flash Tool interface, be sure to uncheck "Wipe data" if you want to save the data, but when downgrading, the system itself will require a reset. If the "Wipe data" checkbox is active (and it will be active when changing the version), all data will be destroyed.
Start the process with the "Install" button. The phone will enter bootloader mode and a progress bar will appear on the computer screen. Do not unplug the cable or press any buttons on the device until the process is complete and the device has automatically rebooted. The first launch after a rollback may take up to 10-15 minutes.
Manual flashing via Fastboot and command line
For advanced users or in cases where the web tool does not work, a manual flashing method via the command line is available. This method gives you complete control over the process and allows you to see detailed error logs if something goes wrong. You will need to open a terminal (Command Prompt or PowerShell in Windows) in the folder with the unpacked firmware.
Put the phone into Fastboot mode by holding down the volume down button while connecting the cable to the PC (or through the command adb reboot bootloader). Make sure that the device is detected by the command fastboot devices. The main firmware script flash-all contains a command -w, which means wipe (clearing data). This is a critical parameter for downgrading.

However, using a ready-made script flash-all.bat (for Windows) is preferable to manually entering commands, since it automatically performs the sequence of flashing the bootloader, radio module and system in the correct order. Just run the file as administrator. If you see an error FAILED (remote: Flashing images for non-active slot), then you need to add a flag --slot=all or switch the active slot.
What to do if a Slot A/B error occurs?
Pixel devices use the A/B partition system. If the script is trying to flash an inactive slot, add the command fastboot --set-active=a (or b) before starting the firmware, or use a modified script that ignores checking the slots.
After completing the flashing of the partitions, you need to make sure that the bootloader is unlocked (if you previously locked it, it may have been reset). Downgrading often requires a second unlock, which again triggers data wipe. The command fastboot flashing unlock will return the device to a state ready to work with custom or old versions of the software.
Data recovery and initial setup
After a successful rollback and first power-on, you will see a welcome screen, as when purchasing a new device. Since the data partition has been formatted, the system will prompt you to restore the backup. Select the recovery source (Google Drive or local cable) and wait for the apps to download.
Please note that some apps, especially banking apps, may not recover their internal data due to changes in the encryption structure between Android versions. You may need to sign in to your accounts again and set up biometric authentication. It is also worth checking the operation of NFC and contactless payment, since resetting the firmware sometimes requires re-linking the cards.
- 📱 Check the Android version in
Settings → About phoneto make sure the rollback was successful. - 🔒 Pass the Google security check (SafetyNet / Play Integrity), which may have been reset.
- 📶 Update all applications in the Google Play Store to be compatible with the current OS version.
Do not rush to install all applications at once. Give the system 10-20 minutes to run in the background to optimize the database and index files. This will help avoid false lags and overheating, which often occur immediately after recovering a large amount of data.
A successful rollback of the Android version is completed only when you have checked the operation of all key functions of the device (sound, network, camera) in normal use mode, and not just the fact that the screen is turned on.
Frequently asked questions (FAQ)
Is it possible to roll back Android to Pixel without losing data?
Technically, direct downgrade with saving user data is not possible due to changes in the database structure and encryption between Android versions. Trying to do this will result in a bootloop. The only way to save data is a full backup before starting and restoration after.
Will the status of the Secure Folder or Samsung Pay analogue be reset?
Pixel uses Google Pay and secure storage. When unlocking the bootloader (which is often required for downgrading), access to protected keys may be lost. After the rollback, you will need to re-configure payment services and, possibly, reset lock screen passwords.
What to do if the phone stops turning on after flashing the firmware?
If the device goes into an endless boot loop, try entering Recovery mode (hold Power + Volume Down) and execute Wipe data/factory reset. If this does not help, you need to enter Fastboot mode again and reflash the device, making sure the integrity of the image file.
Does rolling back the version affect the warranty?
Flashing with the official factory firmware (Factory Image) itself is not grounds for denial of the warranty, since you are returning the device to the state provided by the manufacturer. However, if hardware components were damaged in the process, the service center may notice this.
