Honor View 10 Lite (Honor 8x) bootloader still locked after HCU

[Joining6877]

I tryed to unlock the bootloader of my honor 8x with the HCU by TP after I checked the hcu support list but the bootloader is still locked.
I also followed the guide, the one to see bootcode won't work because it says it's not supported. Thx in advance for the help.
Device info:
Model: JSN-L21
Processor: Kirin 710
Os Version: 10.0.0.263(C55E8R1P1)
Build number: :JSN-L21 10.0.0.263(C55E8R1P1)

As per tutorial and supported model table permanent unlock works for up to Android 9 only https://hcu-client.com/huawei-bootlo...via-testpoint/ need to find a way to downgrade first for permanent bootloader unlock.

Thx for the answer. Unfortunately I can't find the right firmware to downgrade so can I ask for a refound? Thanks again for your time.
