System Update Error

During the update on my Lenovo Vibe K4 Note, I encountered a problem that prompts me while the new firmware is trying to install. It says “Upgrade package signature does not match, cannot install this upgrade package.” After downloading the 28MB file, the update doesn’t push through due the mentioned error.

To resolve, I did free up space on both internal and external storage of the device. Did a reboot then download the update again, luckily it installs the new build firmware.
