If you are interested in downloading and installing Omni ROM on OnePlus 5, then follow our in-depth guide to do so.

OnePlus 5 was the Chinese underdog’s flagship killer for the year 2017. Although short-lived, thanks to its own successor, the OnePlus 5 sported some of the more insane specifications like the Snapdragon 835, 8 GB of RAM, 64 or 128 GB of UFS 2.1 storage, and all at a price of roughly $500. The phone was received very well not only by the media, but also by its customers, and that’s all thanks to OxygenOS, which is OnePlus’ own custom skin atop Android. The OnePlus 5 currently runs Android Oreo, and is guaranteed an update to Android P as soon as possible.

Let’s get back on track with our article today. Omni ROM runs on Android 8.1, and was one of the first official ROMs to have surfaced, and also supports a lot of devices. The ROM is feature-packed, and also has great battery life, so it balances performance and stability as a whole. The ROM also introduced the theming options, which Lineage then enforced in their own builds of Oreo.

The procedure to installing a custom ROM is quite simple if followed right. Although OnePlus claims that the users still retain their device’s warranty, we strictly advice you not to proceed with the guide unless you are an Android enthusiast wanting the most out of your device. With that being said, if you don’t already have an unlocked bootloader, with a custom recovery installed on your OnePlus 5, we have detailed guides on the following as well.
