Install FlymeOS 4 beta leaked on LG Nexus 5


I don’t know, cause I have never tried such things, the only Beta version that I have tried in the Color OS on LG G2 and due to its side effects, I have never tried to flash any Beta ROM on any of my devices. However, that doesn’t stop others to flash such problems on their devices, since you can always return back to your Previous ROM, in case of any problem with the ROM you are installing. While exploring some Chinese Forum, I came across another ROM for Nexus 5, based on Android 4.4.4 Kit-Kat, but in terms of looks and theme, quietly looks like MIUI ROM, Since everything was in Chinese and my Google Chrome doesn’t translate without crashing, so I though to let you people explore the ROM and let us know about your thoughts.

However, remember that this ROM is still in its beta Condition and for Nexus 5 it is a leaked firmware, since there is no Official support provided for this ROM, we will always consider it as a leaked ROM.  In this article, we will show you How to Install FlymeOS 4 beta leaked on LG Nexus 5.
