Xiaomi is yet to announce Android 7.0 Nougat update for the Mi4 while its users can already enjoy Android 7.1, thanks to the release of CyanogenMod 14.1 ROM by the industrious Android custom ROM developers. The CyanogenMod ROM is based on the stock Android 7.1 firmware and hence it gives the original feel and look of the Nougat update without the hassles of installing bloatware.
Although a stable build of CyanogenMod ROM for Android Nougat still seems elusive, the current nightly builds of CM are regularly updated to ensure bug-free software for the end users when the final release eventually comes out.
Consequently, the CyanogenMod Nightly builds will become much more stable and versatile than the OEM released stock ROMs. Interested users can go ahead and root their devices with CWM or TWRP recovery installed, before flashing the custom ROM package, using the zip file provided in the download link below.
- Ensure that you have a computer and the original USB cable handy with you.
- Verify that USB debugging is enabled on your Mi4 by navigating to menu > Settings > developer options. To enable Developer Options, go to menu > Settings > About Phone and repeatedly tap on the build number until the "you are now a developer" message appears on the screen.
- Make sure that your phone has at least 80% battery charge, before you proceed with the CM14.1 ROM installation on your Xioami Mi4.
- The instructions provided in this guide are limited to the Mi4 model. Do not attempt this procedure on any other phone as it will result in bricking or causing permanent damage to the device.
