Install OxygenOS 4.5.0 Update on OnePlus 3 and 3T

It seems as if the OnePlus 3 and 3T are being bombarded with updates! We recently saw HydrogenOS 3.5 update and already a day later, today you can now install OxygenOS 4.5.0 update on the OnePlus 3 and 3T.

It was only recently that OnePlus announced the new OOS 4.5.0 update on the community forums. If you’re wondering that the update is based on Oreo, then I am very sorry to disappoint. The build is still based on Android 7.1.1 Nougat, but it indeed brings some pretty cool changes to the overall system. The OEM is making sure that its users are getting an improved experience with every update they push. It seems like this one is nothing short of it.

Below, we will further discuss the new features, improvements, screenshots, and instructions on how to install OxygenOS 4.5.0 update on OnePlus 3 and 3T.

Instructions to Install OxygenOS 4.5.0 Update

Now that you know what you’re going to get in this update, it is time for you to install OxygenOS 4.5.0 update on your OnePlus 3 and 3T. The fastest, most convenient and hassle-free method to update your device to the latest version is by going to Settings > System Updates. But, in case you haven’t yet received it, you can opt for the manual installation method.

Now, there are two ways for you to install this update manually. You can either flash the OTA zip file, which will update you from OOS 4.1.7 to OxygenOS 4.5.0. However, in case you are on a rooted firmware or a third-party ROM, you will need to install the full ROM zip.

Prerequisites

• Backup your OnePlus 3 and 3T completely: Tutorial
• Charge your device to at least 60% battery level to avoid any interruptions during the update process.

Downloads

— OnePlus 3: Full ROM (Mirror) | OTA zip

— OnePlus 3T: Full ROM (Mirror) | OTA zip

Option 1: Non-rooted Users

If you have a non-rooted device, you are welcome to directly update using the OTA zip. So download the OTA zip for your device.

1. Connect your device to the PC.
2. Transfer the OTA zip file (E.g. OnePlus3TOxygen_28_OTA_055-056_patch_1709231856_c00bc95db92dec.zip) to the root directory (not in any folder) of the device storage.
3. Disconnect the device and open Settings.
4. Scroll down and tap on “System update”. Press the gear icon on the top-right of the window.
5. Select “Local upgrade” and browse the storage for the OTA zip file. Choose the file and select “UPGRADE NOW” option when prompted.

During this process, your device might restart, so be patient and let it do its task. Once the OxygenOS 4.5.0 update is installed, you will be able to enjoy all the new features.

Option 2: HydrogenOS/Custom ROM/Rooted Users

Rooted users will not be able to either install the OTA automatically or manually. You will need to flash the complete OxygenOS 4.5.0 update ROM zip on your device using stock/TWRP recovery.

1. Download the full ROM zip file for your OnePlus device.
2. Connect your phone to the PC in file transfer mode and copy over the ROM zip (e.g. OnePlus3TOxygen_28_OTA_056_all_1709231856_9af15a0.zip) to the storage.
3. Now, disconnect the device and power it off.
4. Boot your OnePlus 3/3T into recovery. To do that, press and hold the Volume Down and Power keys altogether.
5. Now follow step #6 if you have stock recovery or step #7 if your device has TWRP recovery.
6. Stock Recovery:
   • Select “English” as language.
   • Go to Wipe data and cache > Reset system setting.
   • Press “Yes” to wipe the device.
     

     

   • Go back to the main recovery screen and tap on “Install from internal storage”.
   • Browse the storage and select the full ROM zip file. Press on “Yes” when prompted, to start the update process.
   • Once done, tap on “Reboot”.
7. TWRP Recovery:
   • Go to the “Wipe” menu and slide the “Swipe to Factory Reset” button.
   • Move back to the TWRP main screen and select the “Install” tab.
   • Browse the phone’s storage and select the ROM file.
   • Finally, swipe the button on the bottom of the screen to flash the full OxygenOS 4.5.0 update ROM zip.
   • When done, press “Reboot System”.

You might notice that OnePlus has removed the stock music app from the OS. You can now get the app directly at the Play Store.
