Huawei P10 bootloader code fail/Current security patch not supported!

[4pThorpy]

Unfortunately, it seems I'm unable to unlock my bootloader with HCU or DC2.

Could you please advise me if I'm doing something wrong or if there's a known way to downgrade? If this is not possible, could I please request a refund to the user: "4pThorpy"?

Thanks!

Phone info:

VTR-L09
Emui: 9.1.0
Build: 9.1.0.290
