OnePlus released the OxygenOS (OOS) Open Beta 8 for OnePlus 3 which is based on Android 7.0 Nougat. Along with the OS upgrade this build brings up some Nougat features like Multi Window, redesigned settings and notification with quick reply and more. While custom ROM developers and phone manufacturers are concentrating on Android 7.1, they released a beta of Android 7.0. Maybe the final Nougat build will be on 7.1, but we do not know about that yet.
I have installed the OOS Open Beta 8 on my OnePlus 3 and it is working perfect. I’m going to explain every step I took to install this on my OnePlus 3. Backup of your personal data is very important. So, back them up in your computer or cloud. In this tutorial I’m going to explain how to install this Android 7.0 Nougat update on OnePlus 3 via TWRP. If you are on Beta 7, you can dirty flash after wiping the cache. This guide is for experienced users only. I do not take any responsibility if you damage your device.

Steps to install
01. Install TWRP-3.0.2-1.28-oneplus3.img
Reboot to your current TWRP recovery. Press Install > Press Image. Select twrp-3.0.2-1.28-oneplus3.img and swipe to install the recovery required to install the Nougat Beta for OnePlus 3. Now that our requirements done, let’s reboot your phone to recovery again to proceed with installation of OOS Open Beta 8.
02. Install OOS Open Beta 8 on OnePlus 3
Once you are booted to the latest TWRP recovery you need to make sure to wipe everything. A clean installation is highly recommended. You can dirty flash only if you are flashing over another beta build.
Select Wipe > Advanced Wipe. Tick Dalvik / ART Cache, Cache, Data & System then Swipe to Wipe.
After the wipe is complete, go back to the home screen and press Install. Select the OnePlus3Oxygen_16_OTA_016_all_1611302306_cc5d2327b14247fd.zip from your SDcard and swipe to install the image. If you want to have root access, follow the next step. Otherwise, reboot your phone, finish the setup and enjoy.
03. How about Root? (Optional)
If you want to have root, you just need to flash the SuperSU zip file after the ROM. Or, you can simply hit Add more zips after adding the ROM in step 2. This will install the SuperSU binary and the app in your phone.[Note: During the flashing process your device may restart few times. This is perfectly normal.]
