How do I install the bootloader on G6 Play?

[SG775]

I need update my phone for pie (9.0) but the OTA updates doesn't work after me unlock the bootloader of my Moto G6 Play Brazilian Version.

I already installed a factory version, but when the phone is turned on, the bad key still appears.

I just had the same thing happen this weekend. You need to try different TWRP images. I tried like 4 or 5 before finding one that worked. So just download a bunch of them and spend an hour or so trying all of them.
