How can i fix my Huawei p8 lite 2015?, it doesn't update to the latest build.

[Nkululeko Jali]

I am currently running on build b589fter I successfully downloaded my latest update patch from the emui updater b596, it failed to install the update, it showed me this message on shut down:

Http:zh.ui.vmall.com/emotiondownload.php?mod=restore
ERROR
function NO: 10(boot image)
Error NO: 1(Security verify failed!)

How do I fix this and update to b596?
