Huawei boot image verify failed

My uncle has asked me to fix his broken phone. The reward? The phone. I can keep it. Here's a few things: - When you turn it on, it will show something along the lines of "Failed verify boot image - please authorize" for a split second before going into the fastboot rescue screen, asking you to connect to a PC running HiSuite. - Doing this and attempting to recover the phone will result in it telling you that you need to take it to a service desk. - I don't know how it got into this state. Hi, I have a Huawei g630 and when trying to turn it on and it says "Boot image verify failed! Please update to the authorized images." I have tried google, wipe data/factory reset, wipe cache partittion and much more. Any ideas.
