Oppo has released the first Beta version of its Android 6.0 Marshmallow based near stock Project Spectrum ROM for Oppo F1. The Project Spectrum ROM is different from Oppo’s ColorOS. While the ROM keeps some ColorOS awesome features like the Screen-off Gestures, it brings near stock Android interface and features to the device.

In the guide, we show you how to install Oppo’s Marshmallow based near stock Project Spectrum ROM on Oppo F1. Released earlier this year, Oppo F1 is a decent mid-range smartphone running on Color OS 2.1 (Android Lollipop 5.1). If you are excited to tryout the new Android 6.0 Marshmallow on your Oppo F1, just try Oppo’s Project Spectrum ROM.


The current status of Oppo’s near stock Android OS is Beta, which means the firmware is unstable and you may come across issues while using the phone.

Note: The below procedure will wipe your data on your phone. Backup every data (use the Backup & restore app) before updating to the new OS, in case you want to go back to ColorOS.
