How to install sideload OTA update via ADB and recovery

Android is an evolving operating system. It frequently receives OTA (over-the-air) updates released by OEMs. The OTA updates upgrade your devices’ software and firmware to the latest version. OTA updates are released frequently, however, the only catch is that the OTA updates are not released for everyone at the same time. In this guide, we’ll be talking about how to apply update from ADB as soon as they are released. You can even refer to this as an OTA Sideload procedure.

Usually, the OEMs roll over the update for a specific set of regions and users. The reason behind this is that the OEMs do not want their servers to be overloaded by tons of download requests. To ensure smooth downloading of the updates for all users, OEMs only release the update for specific regions and users.

It might take over a week or a month to receive the OTA update officially. And as you keep waiting to receive the update on your device, the excitement and the hype of receiving the update tends to fade away. However, you do not need to worry! OTA updates can be installed manually.  To install them manually you need to download the OTA update file and then install it on your device using ADB sideload. You can sideload android update and sideload firmware using the methods.
