Do not continue after something fails!

Basic requirements

Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
Make sure your computer has adb and fastboot. Setup instructions can be found here.
Enable USB debugging on your device.
Boot your device with the stock OS at least once and check every functionality. Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it won’t work on PixelExperience either!
PixelExperience is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Before Installing Rom

Warning: Make sure you are on OxygenOS 13.1 before installing anything on your device, Steps to do so is

If you are below OxygenOS 13.1 (13.1.0.500)

Download OxygenOS 13.1.0.500 from here.
Install the above via local updater in settings
Let the update boot itself, After device boots, You will need to flash the SAME file AGAIN (yes, its nessesary, making it two times in total)

Note. Enable developer options and usb debugging if local update option doesn’t show up in settings.

You can proceed with next steps now.

Unlocking the bootloader

Note: The steps below only need to be run once per device.

Warning: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or your Google account, or equivalent. Please note that OEM backup solutions like Samsung and Motorola backup may not be accessible from PixelExperience once installed.

Enable OEM unlock in the Developer options under device Settings, if present.
Connect the device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
```
adb reboot bootloader
```
You can also boot into fastboot mode via a key combination:
- With the device powered off, hold Volume Up + Volume Down + Power.
Once the device is in fastboot mode, verify your PC finds it by typing:
```
fastboot devices
```
If you don’t get any output or an error:
- on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
- on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!
Now type the following command to unlock the bootloader:
```
fastboot flashing unlock
```
Note: At this point the device may display on-screen prompts which will require interaction to continue the process of unlocking the bootloader. Please take whatever actions the device asks you to to proceed.
If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
Since the device resets completely, you will need to re-enable USB debugging to continue.

Before Flashing Rom

Warning: This device needs boot vendor_boot and dtbo from stock rom before flashing the rom,so the process to do so is described below.

Download this boot.img file.
Download this vendor_boot.img file.
Download this dtbo.img file.
Power off the device, and boot it into bootloader mode:
- With the device powered off, hold Volume Up + Volume Down + Power.

Flash a the downloaded images to your device by typing:

fastboot flash boot boot.img
fastboot flash vendor_boot vendor_boot.img
fastboot flash dtbo dtbo.img

Installing PixelExperience from recovery

Download the PixelExperience installation package that you would like to install or build the package yourself.
If you are not in recovery, reboot into recovery:
- With the device powered off, hold Volume Down + Power.
Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
Return to the main menu.
Sideload the PixelExperience .zip package:
- On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
- On the host machine, sideload the package using: adb sideload filename.zip.
  Tip: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report Total xfer: 0.98x or adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.
Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.

Note:- If you get error 7 while sideloading:

Download super_empty.img.
Reboot to fastbootD
Use command fastboot wipe-super super_empty.img
Now you can sideload rom, Don’t forget to format data after sideloading.

Note: The first boot usually takes no longer than 15 minutes, depending on the device. If it takes longer, you may have missed a step, otherwise feel free to get assistance.

Tip: If the installation process reports the message "(~47%) adb: failed to read the command: No error", do not worry, the process was completed successfully and you can restart the device.
