Download Oppo A3s Oreo 8.1 Color OS 5 Stock Firmware

Updated On: January 7, 2025 by Selva Ganesh Leave a Comment

Oppo A3s targeted most of the Mid-range users because of Its reasonable price. It comes with Color OS 5.1 based on Oreo 8.1 version. Currently, there is no sign for the Pie update from Oppo. Most of the Manufacturers roll out two major upgrades for their mobile. We should wait for the upgrade to happen. As usual, to get the update, you can try the software update option in settings. But, sometimes, the Auto method may not work. In those situations, you can try below manual methods. Oppo Stock Recovery is different from other mobiles. Yes, you have specific options. But you also didn’t have fastboot support. Maybe we can expect this in the 9.0 version.

If you moved to another region, and can’t get the update, You can try VPN and change it to your Purchased Region and try to get the update in settings. Most of the time, this method will work. There are plenty of free VPNs for Android are available. Don’t download any third-party apps; sometimes, it may trigger the updates process.
