How to Install Oxygen OS 3.0 With TWRP Recovery on OnePlus 2 and Root, Xposed Framework
Step 1: Download the Oxygen OS 3.0 Update file from above. Also, download the Modified TWRP recovery. If you are looking for root and Xposed Framework after installation, download the SuperSU package from the list.

Step 3: Now boot into TWRP recovery. To do so, turn off your device completely and then press and hold the power button and volume down key for a few seconds. Once you see the TWRP logo, that means you have successfully booted into the recovery. Alternatively, if you have rooted device, then use Android apps like the Quick boot or Boot Smart.
Step 4: Once into TWRP, take a Nandroid backup. To do so, tap Backup option and select all the partitions including the system, data, boot, recovery, EFS and cache(optional).
Step 5: Now wipe the current system. To do so, return to home screen and tap the Wipe option in TWRP. Tap Advanced Wipe and select partitions like system, data, cache, Dalvik cache. Do not, in any case, select internal storage, unless you know what you are doing.
Step 6: Now return to the home screen again and tap Install option. Navigate to the Oxygen OS zip file location on your device’s internal storage and select it. Swipe to confirm.
Step 7: Now return to the home screen again and tap Install option. Select Images button at the bottom right. Navigate to the Modified TWRP file location on your device’s internal storage and select it. Now swipe right on the confirmation action button below to install the modified recovery.
Step 8: Once installed, select reboot recovery from below. (Restart the TWRP recovery)
Step 9: Now wipe the current system. To do so, return to home screen and tap the Wipe option in TWRP. Tap Advanced Wipe and select partitions like system, data, cache, Dalvik cache. Do not, in any case, select internal storage, unless you know what you are doing.
Step 10: Flash the Oxygen OS zip file again. Go to the home screen again and tap Install option. Navigate to the Oxygen OS zip file location on your device’s internal storage and select it. Swipe to confirm.
Step 11: Similarly you can flash the SuperSU zip file for root privileges on the Marshmallow update.
Once installation completes, you can wipe the Dalvik cache or simply choose reboot to system option. Once you reboot, you should see the new boot logo. This means that the ROM has been installed successfully. First boot may take a while. If the ROM doesn’t boot or you come across boot loop, a factory reset from the recovery should do the trick. If that fails, you can restore your previous ROM from the TWRP recovery. For Xposed framework. flash the v80 SDK 23 file. However, let the ROM boot first and then try the Xposed Framework.
