Mate 10 pro - Can I downgrade to an older FW

[IndieAce]

I have a BLA-L09 (9.0.0.197 C432E$R1P11), my question is it possible to downgrade the Build to allow me to then use DC Unlocker or another to then unlock the bootloader?
I have seen conflicting information on here as to whether it is possible or not.

Many Thanks

It is not just downgrade about. Read the post very carefully. He needs a particular version to unlock the bootloader by DC.

Once you've downgraded to 8.x bootloader unlocking is available, if dcunlocker does not support the FW other services are available, the issue with 9.x FW is bootloader unlock/lock commands are removed.

Could you be more specific regarding "other services that are available" now?

This is Mate 10 pro. You can unlock the bootloader today with DC if you have firmware lower than v. 145 ( C432.). In OP case he can downgrade to v. 157 (xloader 02) but can not downgrade to v. 145 ( xloader 01). If he try to downgrade from xloader 02 to 01 he will brick the phone.
If you have a good solution I will be happy to see it and I will thank you.
Otherwise please stop providing wrong or unverified solutions.
Just FYI Mate 10 Pro has been released with Android 8.

How did you relock your bootloader?
I want to relock mine mate 10.
My model is ALP-L29
software version : 9.1.0.321(C636E5R1P13).

I used Hisuite to downgrade to basic emui 9.0.
Where do i get the stock fw for emui 9.1 C636?

Did you resolve it? I have emui 9.1, after I unlocked bootloader my phone dialer and messaging stop working, tried to upgrade or downgrade trough Hisuite, no luck. Hisuite said "you have a latest version of firmware"
