QuartzROM and CitrineROM are unofficial ROM ports for the Redmi Note 14 Pro+ 5G (codename amethyst), built and maintained by @thetechguy.69.

QuartzROM: One UI 9 (Android 17), based on Galaxy S24 Ultra firmware, running on the TechAmethyst kernel.

CitrineROM: ColorOS 17 (Android 17), based on OPPO Find X9 Ultra firmware. In development, no public builds yet.

Both are free and not affiliated with or endorsed by Samsung, OPPO or Xiaomi. One UI, Galaxy and ColorOS are trademarks of their respective owners.

Flashing requires an unlocked bootloader. Switching between ROMs wipes data. Use QuartzFlash or the included fastboot scripts. Report bugs on GitHub.
