Has anyone run any custom firmware on the OP5 be it a Custom Recovery or a custom OS. Would just like to know how easy it is to run and how smooth it's capable at doing so!
Please stop distributing false information, as I said in a previous thread OxygenOS has nothing to do with Lineage.
OP, can't help you personally as I've left my 5 stock (think it's the first android phone i haven't unlocked...) But I can tell you that you're best going to XDA and the official Oneplus forum where they have specific unlock/recovery/ROM/root forums.
I can tell you from experience that Oneplus phones are some of the easiest and best to mod, and if there aren't already there will soon be too many good Kennels and ROMs to choose from. They release their kernel source and device trees pretty freely, one of the reasons i like em, I'll always be a tinkerer at heart
I would leave custom ROMs for later, when the phone stops getting updates for instance. Right now I think OOS is a pretty decent OS, very customizable.
