Hey all

I just brought an MI 8 global version from a retailer in the UK Called Three, I found out that they have a vendor rom installed restricting official updates. When I go to chose package and update I get a carrier error and then the installation does not proceed.

Can i unlock the bootloader and install the global rom or will the anti-roll back, stop me from doing this as the rom is old?

Thanks

ROM INFO : 9.6.0(oeah3gfd)
Android ver : 8.1.0 OPM1.171019.011
