Steps to Install Factory Images on Google Pixel 4 and 4XL
Make sure to follow the pre-requisite and download the required files on your PC before trying to install the factory images on your device.
Disclaimer:
Flashing a new system image deletes all user data. Be certain to first backup any personal data such as photos.
Pre-Requirements:
- This guide is for Google Pixel 4 and 4XL only.
- Keep your device charged up to 60% or above.
- You will require a Windows PC/Laptop and a USB Cable as well.
- Android USB Drivers – Download and Install it on your computer.
- Download the latest ADB and Fastboot on your PC.
- Download the factory images and move them to the ADB Fastboot folder on your computer.
Bootloader Unlocking:
- Before flashing a factory image, make sure that your phone bootloader is unlocked. That’s an important part.
- Head over to the device Settings menu > System > Developer options.
- Go to the About phone section > tap on the build number for 7 times and the Developer options will be enabled. Now, go to the Developer options and enable OEM unlocking.
- Now, go to the bootloader mode > once you’re on the bootloader screen, choose the command “adb reboot bootloader”.
- Then use the “fastboot oem unlock” command.
- If in case, the above command won’t work for you, try the “fastboot flashing unlock_critical” command as well.
- In order to confirm the unlocked bootloader, you should see some on-screen prompts on your device. Then you can go on with this guide and your device will be cleaned completely.
Prepare the Factory Image
- After downloading the build zip file from the links given above, extract it on your computer.
- The extracted folder will have a couple of useful files such as the bootloader, OS image, vendor image, and a radio image.
Note: modify the flash-all script to save your data.
After doing all the necessary changes, you can save your file and open a command-line program.
Run the script and install the factory images
You should boot into the device bootloader mode in order to flash the factory image on your Pixel 4 and Pixel 4XL.
- Execute the command “adb reboot bootloader” again. [You can also press and hold down the Volume Down + Power buttons simultaneously for a few seconds to boot into the bootloader.
- Now, check the command line to the file directory with the flash-all script and then run your script from below:
On Unix/Mac, run:
./flash-all.sh
On Windows, run:
flash-all.bat
You can see that script running on the screen. It may take up to a few minutes to install the image. It will automatically reboot your phone after the image is installed. The first boot may take for 10-15 minutes, so please be patient. But if it takes more than that, your device may get into bootloop.
If the flash-all script not working on the device, you can flash all of the images manually. It requires a few extra steps to make sure that your device is in the proper bootloader mode. Then follow the instructions given below:
- First of all, flash the bootloader, then flash reboot, then flash radio, and lastly reboot the bootloader again:
Fastboot flash bootloader <bootloader file name here>.img
Fastboot reboot-bootloader
Fastboot flash radio <radio file name here>.img
Fastboot reboot-bootloader
- Now, flash the image file by following the command below:
Fastboot flash -w update <image file name here>.zip
- It will automatically reboot your device after flashing. But if it’s not rebooting your device, you can manually do it.
Fastboot reboot
After the device boots up, make sure that you have the latest factory images with you. If you choose to renew the flash-all script, your all data should be cleaned.
