If you’re still using a POCO M2 Pro, Redmi Note 9 Pro, Note 9S, Note 9 Pro Max, or even the Redmi Note 10 Lite, you’ve probably noticed that official updates have slowed down or completely stopped.
But good news: there’s a new custom ROM out that brings your device up to Android 15, and it runs ColorOS 15 basically the same sleek software found on OnePlus phones, known as OxygenOS 15.
This isn’t just a rushed port either. It’s a well-thought-out project by a developer named DarkSky4You, who went the extra mile to make sure this ROM feels smooth and stable enough to use every day. Think of it as a full makeover for your phone inside and out.
What Makes This ROM So Special?
What’s exciting here is that you’re getting the Android 15 experience, but wrapped in a modern, OnePlus-style interface, and it actually works really well on these older Xiaomi phones.
You can do cool stuff like unlock higher frame rates in games, back up unlimited photos to Google Photos (yes, really!), and the system even tricks apps like Snapchat and the Play Store into thinking you’re on a newer flagship device. So stuff just… works better.
And yes, the Play Store passes all safety checks, so you can install your favorite apps without annoying compatibility errors. Even some advanced features like dock customization and screenshot privacy settings are baked in.
Are There Any Issues?
There are a few small things that don’t work, mostly because of how Xiaomi’s hardware and the OnePlus ROM are built differently. For example, Face Unlock and Secure Folder don’t work, and a few gestures might be glitchy or not respond. But nothing game-breaking.
How Do You Install It?
You’ll need a custom recovery like OrangeFox (which most ROM flashers already have). You’ll boot into recovery, wipe a few things, flash the ROM file (Download ColorOS 15) , and reboot.

There’s one thing to watch out for: if the ROM file is over 4GB, make sure to copy it to your internal storage or flash it using ADB sideload, since SD cards might not work properly.
Also, give it some time to settle after the first install. Don’t panic if it feels a little laggy at first—within a day, it should smooth out nicely.
So… Should You Try It?
If your device is starting to feel outdated, this ROM gives it a whole new life. You’ll feel like you’re using a completely different (and much newer) phone. It’s slick, modern, and pretty reliable, considering it’s running Android 15 on mid-range hardware from a few years ago.
Plus, it’s just fun to see what your phone is really capable of when you go beyond the stock software.
