Google Pixel 3a and Pixel 3a XL both are now receiving Android 10 stable update. To install the new factory image immediately, this article explains exactly how. After successful Beta testing, Google has finally started to push Android 10 on all devices. Further, the brand has also decided that it will now have version number as the name rather than giving titles inspired from desserts. So, Android 10 is the complete name for Android Q. If you are looking to manually update your Google Pixel 3a or Pixel 3a XL, read ahead for the complete procedure that even works with phones that have been rooted, are running custom ROMs or other modifications.
Right before we begin, do make sure you have a complete backup of all your phone data as a new firmware install might lead to a factory reset. Further, for major upgrades such as this, we recommend you start fresh and do the factory reset yourself even if the update doesn’t initiates it. Lastly, it is recommended that you read the whole guide first before implementing it in order to get a better grasp on the procedure.

Step 6 – Now extract the downloaded file anywhere in your computer. Go to the folder sargo-qp1a or bonito-qp1a and then copy/paste all the files to your Fastboot directory.
Note: If you followed our tutorial on setting up Fastboot on your computer, there is a 99% chance your Fastboot directory will be the platform-tools folder in your Android SDK directory.
Step 7 – From the factory image files in your Fastboot directory, do the following depending which OS you are on:

- On Mac: Run the file “flash-all.sh” using Terminal.
- On Linux: Run the file “flash-all.sh”.
Step 8 – That’s pretty much that you had to do for flashing the Android 10 factory image on your Google Pixel 3a / Pixel 3a XL. Now wait and watch as the process is completed — or follow the on-screen instructions on your phone if in case you have to unlock the bootloader.
Step 9 – After the installation completes, the phone will boot now and it might take about 5 minutes to boot on your first time. So, please wait with patience!

Backup and Other Important Tips
Please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps.
Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. Read: How to Backup Android Apps, Text Messages, WhatsApp, Call History.
If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up. [Tutorial: How to Backup Android Phone using TWRP]
A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow, Nougat and Oreo.
2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
3. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.
