Keeping its promise to fans, OnePlus finally launches its new operating system for OnePlus One phones. Named as Oxygen OS, it's based on Google's latest Android Lollipop OS.
OnePlus states the Oxygen OS is light in nature and won't be system heavy. The OS also features several essential features, screen gestures, quick settings and an improved file manager.
OnePlus has also made a feedback app available for download on Oxygen OS which will be able to send across user's feedback to OnePlus in a single click.
So all you need to do is download the Oxygen OS ROM from here and flash the OnePlus One smartphone with the latest ROM. Following are the step-by-step guide to achieve the needful.
Note - Please make sure to back up all your important data and files before going further. Flashing OxygenOS onto CM requires a complete system wipe, so in the process you will lose all of your data.
Please proceed only if you are confident in your abilities to flash a custom ROM. This guide exists to help you flash OxygenOS, but things can still go wrong if not followed correctly. While rooting and flashing will not void your OnePlus warranty, any damage caused by improper flashing is not covered under warranty.
The following instructions assume you have Fastboot and ADB installed.
- You need to flash a system recovery onto your device. OnePlus recommends using TWRP for the process. Please download the recovery image to your computer.
- Boot your phone into fastboot mode by holding down the power button and the volume up button together. When you see the fastboot logo, connect your device to your computer.
- In your computer terminal window, locate the folder where you put the recovery image and run the following commands:
- fastboot oem unlock (You can skip this step if your phone's bootloader is already unlocked).
fastboot flash recovery . Image file should be the TWRP recovery image.
You should now have the recovery installed.
Unzip oxygenos_1.0.0.zip file you've just downloaded. In the uncompressed file you will see a oxygenos_1.0.0.flashable.zip file. Copy oxygenos_1.0.0.flashable.zip to your phone. If you're using a Mac system, you can use Android File Transfer to solve the purpose.
Boot into recovery mode again. You can do this on your OnePlus One phone by holding down both the volume down key and the power button together.
Once you are in the recovery interface, factory reset (systemp wipe) your OnePlus One smartphone.
After the wipe, locate the oxygenos_1.0.0.flashable.zip and install. Confirm flash. This command will successfully flash OxygenOS onto your device.
After the flash succeeds, you can reboot the device, which will take you to the new OxygenOS.
