OxygenOS 1.0.2
OnePlus releases OxygenOS version 1.0.2 for OnePlusOnePlus

OnePlus has issued a new OxygenOS update – version 1.0.2 - for its 2014 flagship smartphone.

This release contains fixes for the infamous Stagefright vulnerability discovered by Zimperium.

Notable mobile manufacturers including Motorola and Sony have recently announced that they will release software updates for their devices to patch the Stagefright bug.

For the uninitiated, Stagefright is a media playback engine in Android OS, which unpacks and plays the multimedia message service (MMS). This vulnerability could allow hackers to insert malware in the videos and access the phone, without providing a chance to evaluate the video.

Those OnePlus One owners who are currently running OxygenOS are advised to upgrade to the new version.

Before the installation do not forget to create a backup for all the data on your phone. If you are already on OxygenOS, there is no need to perform a reset. Also, install Fastboot and ADB.

How to install OxygenOS 1.0.2 on OnePlus One

Step-1: Flash TWRP recovery on your PC

Alternatively, you can follow these steps to install TWRP manually:

Boot OnePlus One into fastboot mode. Hold Power and Volume up buttons together. When the fastboot logo shows up, connect your phone to your computer.

For Windows:

In the terminal window, find the folder where you put the recovery image and run the following commands:

  • fastboot oem unlock (Skip this step if your phone's bootloader is already unlocked)
  • fastboot flash recovery (The image file should be the TWRP recovery image)
  • fastboot reboot

For Mac

In the terminal window, find the folder where the recovery image is placed and run the following commands:

  • ./fastboot oem unlock (Skip this step if your phone's bootloader is already unlocked)
  • ./fastboot flash recovery (Image file should be the TWRP recovery image)
  • ./fastboot reboot

The TWRP recovery should now have been installed on your OnePlus One.

Step 2: Unzip the OxygenOS file you downloaded. You should see a flashable .zip file, copy it to your phone. Mac users can use Android File Transfer

Step 3: Boot OnePlus One into recovery by holding down Volume Down and Power buttons together

Step 4: Perform a factory reset. Note that this process will erase all data of your phone, so ensure that you have created a backup

Step 5: Navigate to install and find flashable.zip and confirm installation

Step 6: When the installation is completed, reboot the phone

If you want to revert to CM, ensure that you have installed TWRP or CM recovery. Perform a factory reset before you flash.
