Need help with brick Huawei phone

I really need help trying to get the bootloader code my Huawei Y301-A1. When I try to boot the phone up its come up with the message "image signature verify fail". I have tried to contact Huawei for the code, but they wont help. I always tried to use DC-unlokcer but it wont work if my phone is not in download mode. (which I can not get into) The only program that I can get to detect my phone is fastboot and DC-unlocker.
