Help with firmware update

Hi guys, Just got my mate 7 and love it BUT, I'm on Vodafone Australia and they are having issues with updates. I'm stuck on 127SP02 with no available updates. I have downloaded both firmware updates from Huawei but when reading the attached doc, it says something about the update file and a vendor file. Obviously I have no vendor file so will i do any damage by running the firmware upgrade on its own? Will do the 4.2.2 update , then the lollipop one.

Thanks
