I was not able to update my device due to modification in my android by some security or antivirus app. Some of my phone app had modified basic system files or security app was restricting me to update root files with new OTA update.
Hence, After lot of search on internet and finally got few solutions to cannot update software problem. As I said Android apps had modified my some basic files so my work was to disable all my apps for awhile till software up-gradation is completed successfully. Disabling any blocking like Antivirus or Security app would allow access my root files to get modify with new updates.
To temporary disable all the installed apps without removing them, I just restarted my device in Safe Mode. What is safe mode ? Safe mode implicates that all, apps which you have installed except product manufacturer (like Samsung, HTC, etc.) default apps will be disabled.
Once I booted my device in Safe mode, all my manually installed apps to got de-activated temporary causing no distraction in Android software upgrade.
