Required Android build for Huawei Mate 10 Pro BLA-L29 Bootloader unlock?

[sh-bla09]

Hello,

I would like to kindly ask you, what is the latest build number for Huawei Mate 10 Pro BLA-L09, which supports the Bootloader Unlock with any method? Therefore the rebranding to BLA-L29?

Everywhere is mentioned, that it does not support the android 8 with new bootloader security, but I did not find, which version started the new security.

Is the version 8.0.0.137 C432 good for bootloader unlock or does it need even older? Which one please?

I have BLA-L09C432 single sim, I am already on A9 9.0.0.161, but I read, that downgrade is possible.
I want to (at least) unlock the bootloader and/or rebrand to BLA-L29 dual sim.

Thank you.

We do not have such information sadly. It depends on security patch not on firmware version more or less. We certainly can not unlock bootloader for it or debrand at the moment.

Thank you.

Well, neither solution if it is downgraded to a older firmware with older security patch? Or the security patch is not downgradeable?

I was waiting 2 years so the warranty goes off on my mobile, I see, I did a mistake by the waiting

No solution for it whatsoever.
