In this guide, we will show you the steps to flash the latest PixelOS ROM based on Android 14 onto your OnePlus 9 Pro. The ninth iteration of the device from this Chinese OEM is to date one of the most popular players in custom development. One major reason for the same is the fact that it’s the last device in the lineup that still has a working unbrick tool [MSM], so users and developers both are ready to step into uncharted territory without much risk involved.
In this regard, the first thing a tech enthusiast usually does is flash a custom ROM, more so if they own a onePlus device. The reason for the same is hardly a secret either- the quicker you leave the bloated revamped OxygenOS [or rather ColorOS], the better. In this regard, they are fortunate enough that the device is blessed with a plethora of Custom ROMs. So which one should they ultimately opt for?
Well, if you are looking for a clean stock usage experience with a touch of Pixel goodies, then your search stops right here. Not to mention the fact that a fast, snappy, and performance-enhanced ROM is on the cards as well. So on that note, let’s make you aware of the steps to install the latest PixelOS ROM based on Android 14 onto your OnePlus 9 Pro.

How to Flash PixelOS Android 14 on OnePlus 9 Pro
Before starting with the process, make sure to take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
STEP 1: Install Android SDK
First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.
STEP 2: Enable USB Debugging and OEM Unlocking
Next up, you will have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking process.
So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.
STEP 3: Unlock Bootloader
Next up, you will also have to unlock the device’s bootloader. Do keep in mind that doing so will wipe off all the data from your device and could nullify its warranty as well. So if that’s all well and good, then please refer to our detailed guide on How to Unlock Bootloader on OnePlus 9, 9 Pro and 9R
STEP 4: Download PixelOS Android 14 ROM for OnePlus 9 Pro
- You may now get hold of the ROM and its associated files from below:
PIXELOS ONEPLUS 9 PRO: DOWNLOAD LINK PIXELOS FIRMWARE FLASHER: DOWNLOAD LINK KERNELSU FOR ROOT [OPTIONAL]: DOWNLOAD LINK super_empty.img [OPTIONAL]: DOWNLOAD LINK
- Rename the ROM to rom.zip and transfer all the files to the platform-tools folder.
NOTE: We are using super_empty.img from LineageOS. It’s not a cause of any concern as it should be supported across all AOSP ROMs for our OnePlus 9 Pro. But still, if the developer has provided his own super_empty.img file, then please go with that. Moroever, you could check for the latest version of that file from here [only download the super_empty file from there]. As far as the reason for the flashing of this file is concerned, it is done to avoid Error Update 7 (status 1).
STEP 5: Boot to Fastboot Mode
- Connect your device to the PC via a USB cable. Make sure USB Debugging is enabled.
- Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This will launch the Command Prompt.
- After that, type in the following command in the CMD window to boot your device to Fastboot Mode
adb reboot bootloader
- To verify the Fastboot connection, type in the below command and you should get back the device ID.
fastboot devices
- If you’re not getting any ID, then please install Fastboot Drivers on your PC.
STEP 6: Flash PixelOS Firmware
- First off, wipe the super partition to avoid Error 7:
fastboot wipe-super super_empty.img
- Then go to the extracted firmware folder and launch Pixelos_Flasher.bat.
- It will flash the firmware. Once done, use the below command to boot to recovery:
fastboot reboot recovery
STEP 7: Install PixelOS Android 14 ROM on OnePlus 9 Pro
- From recovery, go to Apply update -> Apply from ADB.
- Then type in the below command in the CMD window to sideload the ROM:
adb sideload rom.zip
- Once done, select Factory reset -> Format data/factory reset.
- Finally, select Reboot System to boot to the newly flashed OS.
NOTE: If your device boots to the Fastboot Mode instead of the OS, then boot your device to Fastboot Mode by going to Advanced > Reboot to Bootloader. Then use the fastboot set_active other command to change the current active slot and then flash the ROM via adb sideload to this partition as well. Then try booting to the OS and you should have no issues this time around.
STEP 8: Root via KernelSu [Optional]
If you want to root your device running PixelOS, then proceed ahead with the below steps [Do note that once rooted, your device will fail the Play Integrity Test. So, you’ll have to carry out the steps mentioned in this guide to pass the test].
- Rename the file to kernelsu.zip and transfer it to the platform-tools folder.
- Then enable USB Debugging on your device and connect it to PC via USB.
- Now open Command Prompt inside the platform-tools folder.
- Then type in the below command to boot your device to recovery:
adb reboot recovery
- Now, type in the below command to sideload the kernelsu.zip file:
adb sideload kernelsu.zip
- Finally, use the below command to boot your device to the rooted OS:
adb reboot
