As I already said at lineage thread too, my p20 pro was hard bricked when I tried to create an unlock tool for the public.I'd like to know the answer to this as well. I know its all about the Bluetooth these days but I'm a fan of wired headphones. [emoji442]
I sent it to Huawei to fix it, but instead of fixing it they went the easy way around and they changed my motherboard for free. This means that I'm locked again without any way to unlock.
So my days here ended.
If only Huawei allowed us to unlock the devices I could do some magic.
It was my first and last Huawei because I don't like having proprietary stuff at my phone , I don't like being watched and I don't like to wait for a security patch for months and I don't like the fact that they support a device for two major updates and then abandon it.
If I wanted all the above , I could as well buy an iPhone XS max.
I sold it now that it sells at a good price , got almost all my money back and I'm waiting for pixel 4xl.
Goodbye Huawei and good luck.
