Downgrade OnePlus 2 from OxygenOS 3.5.5 to OxygenOS 3.1.0

In this guide, you will be able to learn how to Downgrade OnePlus 2 from OxygenOS 3.5.5 to OxygenOS 3.1.0. The OnePlus 2 was released almost an year ago, and while it didn’t at all live up to its expectations, it was still considered to be a crowd favorite. Sporting the best specs in any phone at that time, the OnePlus 2 rocked a Snapdragon 810, 4 Gigabytes of RAM, Adreno 430, a great camera, and an amazing build. In spite of the crazy sepcs and the good build, it did manage to fall down way below under the price bracket of $400.

Very recently, the OnePlus 2 got an update to OxygenOS 3.5.5, which introduced a new UI with a ton of new features. However, many users (including me) have been facing annoying network drop issues while using both the SIMs. Being a dual SIM device, the OnePlus 2 is facing issues where the network drops to zero while activating both the SIMs. The only way to counter this is to disable one slot, or downgrade your device.
