Almost everything in this world is never constant rather is evolutionary; so are smartphones and their operating systems. The manufacturers and developers of the smartphone devices regularly roll out OTA updates so as to keep the devices and the system in accordance to the recent developments in the relevant field of technology.
These OTA updates are however not released to all the users at one time rather a phased manner approach is adopted. Hence it might take longer for a few users to receive such updates on their device. If you are a user who cannot wait to update your device to a newly rolled out version which is not yet available on your device but has been released; this article will guide you through the process of updating manually.
OTA or over the air technology is generally used to distribute Software Updates, configuration settings and others directly from one central tower to portable devices like Smartphones and tablets. It is through this technology that Firmware and Other updates are transferred directly over the air from wireless careers. It does not need USB and other connectivity methods to upgrade any device or software or applications.
The manufacturers in order to ensure a smooth transition of the update over download servers, roll out the updates gradually on the basis of region and the device model. The process takes around a month to cover all the users. Hence it becomes really difficult for certain users who are tech freak to wait for a month. In such cases, OTA updates can be installed manually. Although the manufacturers do not give a direct option for a manual installation of the update it is possible to do so using the .zip file of the update. This file can be considered the passage to the update. The .zip file of the update is generally available publicly over the virtual world. Many users will get confused between Android SDK and ADB drivers, here is the explanation.
Now without any further delay let us get to the process of updating the device manually using .zip file. Before we begin the process make sure that you downloaded the .zip file of a relevant update on to your device.
