What is Pixel Experience ROM?

As is evident from its name, Pixel Experience is based on the stock AOSP experience that comes with the Pixel devices. So apart from a clean user experience, you will also be getting tons of Pixel goodies and re-installed Google Apps [GApps]. However, even then, it wouldn’t give you a bloated experience as it has managed to strike a fine balance between features and stability.

Owing to all these reasons, it is no hidden secret why it has scaled the popularity charts and quickly became the go-to choice for numerous tech enthusiasts. If you also echo the same thought process, then this guide will show you the path to welcome this ROM onto your device right away. Follow along.

Install Pixel Experience ROM Android 13 on OnePlus 9RT

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.

Update Firmware to Android 13

If your device is currently having a firmware version older than OxygenOS 13.0 F.13, then you will have to flash this latest firmware “two times” using the instructions given below:

Download OxygenOS 13.0 F.13 and send it to your device’s Internal Storage [but not inside any folder]
Then go to Settings > About Phone> Tap on Build Number 7 Times. This will enable Local Update.
Now go to Settings > System Update and tap on the overflow icon and select Local Update.
Navigate to the OxygenOS 13.0 F.13 file and select it. It will be flashed onto your device.
Now follow the exact same steps once again to reflash the OxygenOS 13.0 F.13.

If your device is currently on the firmware version OxygenOS 13.0 F.13, then you will still have to flash this firmware “once” using the instructions given below:

Download OxygenOS 13.0 F.13 and send it to your device’s Internal Storage [but not inside any folder]
Then go to Settings > About Phone> Tap on Build Number 7 Times. This will enable Local Update.
Now go to Settings > System Update and tap on the overflow icon and select Local Update.
Navigate to the OxygenOS 13.0 F.13 file and select it. It will be flashed onto your device.

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 on OnePlus 9RT

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 the Bootloader of any Android Device.

STEP 4: Download Pixel Experience ROM & Recovery for OnePlus 9RT

Now, get hold of the Pixel Experience ROM, Recovery, boot, dtbo, and vendor_boot files from below:
```
OnePlus 9RT [martini]: ROM | Recovery | boot | dtbo | vendor_boot
```
Once all the files have been downloaded, transfer them to the platform-tools folder on your PC.
Now rename the ROM file to rom.zip, recovery to recovery.img, boot to boot.img, dtbo to dtbo.img, and vendor_boot to vendor_boot.img.
We have just done the rename so that it becomes easier to type in the Command Prompt window.

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
```

STEP 6: Flash boot vendor_boot and dtbo

First off, execute the below command to flash dtbo:
```
fastboot flash boot boot.img
```
Then type in the below command to flash the vbmeta:
```
fastboot flash vendor_boot vendor_boot.img
```
Finally, execute the below command to flash dtbo:
```
fastboot flash dtbo dtbo.img
```

STEP 7: Flash Pixel Experience Recovery

You will now have to flash the Pixel Experience recovery onto the recovery partition of your device. So execute the below command for the same:
```
fastboot flash recovery recovery.img
```
Once the flashing is complete, use the hardware keys to bring up the Recovery menu and hit the Power key to confirm it [you may also use the fastboot reboot recovery command].
Your device will now boot to the Pixel Experience Recovery [it is a touch-based recovery, so you could use it without interacting with the hardware keys].

STEP 8: Copy Contents of Slot A to Slot B

To maintain consistency of the firmware versions between the two partitions on your device, we will now be copying all the contents of Slot A to Slot B.

Download the copy-partitions ZIP file and transfer it to the platform tools folder on your PC. Also, rename it to cp.zip.
Then on the Pixel Experience recovery, select Apply Update > Apply from ADB.
After that, open CMD inside the platform-tools folder and execute the below command
```
adb sideload cp.zip
```
Once flashed, go to Reboot and select Recovery. Your device will reboot to Pixel Recovery.

STEP 9: Factory Reset Device

From the Pixel Experience Recovery, go to Factory Reset.
Then select Format Data/Factory Reset > Format Data.
Your device will now undergo a reset. Once done, you shall get the “Data wipe complete” message.

STEP 10: Install Pixel Experience ROM

From the Pixel Experience Recovery, go to Apply Update > Apply from ADB.
Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter.
This will launch the Command Prompt. So type in the below command to flash the ROM file via Sideload:
```
adb sideload rom.zip
```
The process will now begin and once done, you shall get the Total xfer: 1.00x message [Got an error? See FAQ below].
Now go back to the home screen of the recovery and select Reboot System Now. Your device will now boot to the newly installed OS.

That’s it. These were the steps to install the Pixel Experience ROM based on Android 13 onto your OnePlus 9RT. If you have any queries concerning the aforementioned steps, do let us know your doubt and the device that you are using in the comments. We will get back to you with a solution at the earliest.

Fix: Error During ADB Sideload

If you get one of the below error messages, then it signifies a successful installation and you could reboot the device to the OS without any issues:

Total xfer: 1.00x
adb: failed to read command: Success/No error
adb: failed to read command: No error
(~47%) adb: failed to read the command: No error
adb: failed to read command: Undefined error: 0

On the other hand, if you get Error 7 while sideloading the Pixel Experience ROM, then here’s how to fix it:

Download super_empty.img and transfer it to the platform tools folder on your PC.
Then reboot your device to FastbootD and use the below command to flash super_empty
```
fastboot wipe-super super_empty.img
```
Once done, type in the below command to flash the Pixel Experience ROM
```
adb sideload rom.zip
```
Finally, go to Factory Reset > Format Data/Factory Reset > Format Data [compulsory]
Once done, reboot the device to the newly installed OS via Reboot System Now.
