  • Download ADB and install it on your computer.
  • Enable USB Debugging on your Android device.

Steps:

  1. Connect your Android device to your computer via USB Cable.
  2. Go to the folder where ADB is installed on your computer.
  3. Open command prompt/power shell window from inside this folder:
    1. Hold down Shift Key + Right Click on empty space inside the folder.
    2. Click on ‘Open command window here’ or ‘Open PowerShell window here’.Open-PowerShell-Window-Windows
  4. In the command window/PowerShell window, execute the following command:
    adb logcat > ota_link.txt

Android OTA Update – How it works?

System updates on Android do not happen to all devices at the same time. And if your phone is locked under a carrier, then the system updates might get delayed even further. Even if the device is unlocked, there is no guarantee that you will receive the update on day 1 of its release.

Android manufacturers, including Google, follow a process called staged rollout. In the concept of a staged rollout, the system updates are released to a device in a controlled manner. For example, if Google announces that Pixel 4 is getting an update today, it does not mean that the update will be available for all the devices across the world. More often than not, the update will first be rolled out to one or more handpicked countries. A Pixel 4 user in Canada might get the update while another in the United States will not. Likewise, the update is rolled out to different countries at a different point of time.
