Sometimes we don’t receive an OTA update on our device, then we have to manually install the OTA update via ADB Sideload. ADB is an Android Debug Bridge to communicate with a device.

However, Recovery mode is an easy way to install any custom ROMs and OTA update on any Android Device. If you don’t want to use any kind of recovery mode to install the OTA update, then you can apply update from ADB sideload.

The ADB Sideload is one of the options available to install the OTA(Over-the-air programming) update manually. You should have OTA update Zip file that you can manually flash.

Some manufacturers don’t give you directly OTA zip file, but users who receive OTA update, share this publicly. If you don’t receive an OTA update, you can download the update.zip file from the OEM website and easily install it on your device.

Note ⇒ This method might not work properly on all Android Devices. If this works on your device, then it is good otherwise not. You can use the TWRP Recovery mode for installing any OTA update instead.
