In this guide, we will show you the steps to flash the latest OxygenOS 15 based on Android 15 onto your OnePlus 9R device. The fifteenth iteration of the OS build has just been rolled out by the Silicon Valley giant and OnePlus was quick to jump ships over to this bandwagon.

But what about the ones that have missed the bus, in other words, are no longer eligible for this update [since they have reached the EOL]?
Well, there’s always an option to flash a custom ROM like LineageOS, or crDroid, among others.
