I am using lenovo A6000+ phone.
I have rooted it earlier with kingroot app, and recently there was system update, so I downloaded update and tried to install it but at the time of rebooting there were options for system recovery, first I choose to "install update from adb sideload" but that gave me an error. so I again restarted my phone and clean the cache, then again rebooted and chose adb sideload but there is nothing happening.
So I again rebooted and chose factory reset. But even after doing factory reset to my phone, it is still giving me options for system recovery.
How can I start my phone, can I install that update externally and start the phone and how?
