OxygenOS Is Out! Here’s How To Install It on OnePlus One

Good day, OnePlus One users! I have been waiting for this moment for the past two months myself, and the day has arrived. OnePlus not-so-recently announced its latest ROM, which was known as OxygenOS. This Custom ROM was hyped for a long time. OxygenOS was meant to be released on the 12th of February, but it was only announced back then. From then onwards, every single OnePlus One user was eagerly waiting for the Update to arrive. Recently, OnePlus also declared a date (27th March) on which the ROM was supposed to be released. Alas, they once again didn’t keep their promise due to some Certification problems. But, today, OnePlus proudly announced its very own Custom ROM. I installed it the minute it was released, and yes, it is not an OTA. You need to flash OxygenOS like any other Custom ROM. If you happen to own a OnePlus One, and really want to enjoy the sweetness of the new OxygenOS, then this guide is specifically made for you! Here are the simple steps that you need to follow in order to install OxygenOS on your OnePlus One!
