But in order to get that ROM you need an unlocked bootloader, breaking integrity (best case scenario is device level integrity, you can’t get strong anymore). Google RCS will sort of work if you can pass Device, but in my experience things break silently if you don’t pass Strong (massively delayed messages, messages not sending, and RCS randomly disabling for no reason at all in the middle of a conversation).
You don’t even have to be rooted. RCS won’t work using a non-rooted custom ROM.
