Huawei USB COM 1.0

[dcunlockeruser01]

Hello Valdemaras,
my Mate 9 MHA-L29C432 is in permanent "Huawei USB COM 1.0" mode.
Is there a solution for this.
When I flash the "MHA-Downgrade-Board-A074-7.0.0_r1.dgtks" DC-Unlocker starts in testpoint mode.
But after writing the "VECTOR partition update" DC-Unlocker restarts
and then waits for the "Fastboot mode".
I can not put the Mate 9 into "fastboot mode" with "Vol -" and power.
Could you help me ?
Thank you in advance.
Enclosed a log file.

You should try to use loader from dc-phoenix matching your phone's cpu, to see if it enters fastboot then, and attempt flash it if it does..

I have already tried all Kirin960 loader files from dc-phoenix and HCU (its the same) ...

If it does not go into fastboot then no go for it only main board replacement.
