Updating image android
This page contains full OTA update packages that allow you to restore your Nexus or Pixel device's original factory firmware.You will find these files useful if you have experienced a failure to take an OTA.This has the same effect as flashing the corresponding factory image, but without the need to wipe the device or unlock the bootloader.These files are for use only on your personal Nexus or Pixel device and may not be disassembled, decompiled, reverse engineered, modified or redistributed by you or used in any way except as specifically set forth in the license terms that came with your device.Your downloading of the system image and use of the device software may also be subject to certain third-party terms of service, which can be found in Settings environment variable or change into the directory containing the executable.Also be certain that you've set up USB access for your device, as described in Run Apps on a Hardware Device.Refer to this Android developer page to determine which version of Android your device is running.
One notable exception to this general rule is Google’s line of Nexus devices.
Since those devices were specifically released in order to showcase Google’s unaltered version of Android, your Nexus smartphone should prompt you to upgrade your software whenever a new version is released.
Another exception are any low-end devices branded with Google’s Android One platform.
The System Update option should be located under either the Settings or the About Phone menu.
Since this delivers an update directly to your mobile device, you may want to connect to a Wi-Fi network before beginning the update process.
While Android may be handily beating Apple and other competitors in terms of market share, the open source operating system is struggling in the battle against malware.
