What is this?
A quick guide on how to install Derpfest using Windows. You must be on Stock (Feb build) before installing Derpfest. Flashing from another "ROM" or Android Build will not work. These instructions will wipe your device. You have been warned.
*instructions for updating or ”dirty flash” at the bottom of page. ota update will not currently work.
(thanks do DarkPlayer for the inspiration for this guide).
Requirements:
- A computer or laptop with a chromium based browser, such as Chrome, Edge, Brave etc.
- Supported Models for Derpfest Raviole: Pixel 6 Pro (Raven) and 6 (Oriole)
- Latest platform-tools (fastboot tool) and usb driver installed. If you do not have the latest platform-tools installed, you will get errors when you try to flash. If you've previously installed the "minimal adb" tool, it is very important to uninstall/remove this tool and the folder location.

Instructions for flashing Stock Android:
(Preparing your phone to flash Derpfest - must be on Stock Android .003 Feb build)
- Before flashing Derpfest, Pixel 6/Pro must be a freshly flashed Stock Android February version, and device will need to be wiped.
Go to the Official Factory Images Developer Page, find your model and click on the blue “flash” link beside the 1st February Build (12.0.0 (SQ1D.220205.003, Feb 2022)). This will open a new window that will take you to the Android Flash Tool (AFT) website for this specific February build.
**you need to be on .003 2nd Feb build to flash Derpfest** - Disable any adblockers and popup blocker (important for this tool to work properly)
- Turn your phone off, and without a cable connected, boot into Fastboot Mode by holding Power and Volume Down. Connect your phone to your computer and refresh the Android Flash Tool webpage.
- A window will appear called Grant access to ADB keys - click “Allow ADB access”.
- A new adb pop-up window will appear. Click on your device and hit “connect”
- Highlight your device under “Select Device” option.
- The only options you need to enable here are “Wipe Device” and “Force Flash All Partitions” - uncheck all other options. *Warning: Your phone will be wiped.
- Click on “Install Build”. Your device will restart a few times. Very important – Do Not Touch Your Phone, even when you see the “Fastbootd” menu with options – leave it alone. Let the device boot up by itself. Process takes between 8 and 30 minutes depending on your internet and usb connection speeds.
Installing Derpfest:
- Download the Derpfest zip file for your specific device. The download link will be "pinned" in the Derpfest Telegram Group.
example of filename: derp_raven_v11.zip
(do not download from another source such as Sourceforge)
(important: Flashing the wrong model can cause your device to "brick" meaning you will need to get it replaced. Triple check the filename is the same model as the "Device Name" listed in fastboot mode. You have been warned. - Turn your phone off, unplug usb cable and boot up into Fastboot Mode. Then plug your phone into your computer.
- Using windows explorer, locate the Derpfest zip file you downloaded and do not open it. In the address bar erase everything and type in cmd and hit enter. This will open a command prompt window in the same folder as the Derpfest image.
- Type the command fastboot --version to check you are using the latest version of Fastboot (in this case version 32.0.0-8006631.
Then type the command fastboot devices
(the device name will appear in the command window) - Now type in the command fastboot -w and hit enter (this will just wipe the device to prepare for the installation, errors are normal. only use when coming from stock, not updating Derpfest)
- Last step is to flash Derpfest. The flash command is simple:
fastboot update <filename.zip>
*For example, on Raven, the command might be:
fastboot update derp_raven_v11.zip
On Oriole, it might look like: fastboot update derp_raven_v11.zip
(These filenames could change at anytime and are just examples)
Let the phone flash (it will restart into fastbootd mode). Don’t touch it. You will know the flash has completed when you see the Android Boot Animation (this is normal) and then the Android Setup Wizard.
Note: Process takes about 10 minutes. Check the command window for any errors or issues and if experience any problems, post the screenshot in the Derpfest room.
Updating Derpfest (dirty flash):
- Currently, the only way to update Derpfest from a previous version of Derpfest, is to flash the latest Derpfest image through fastboot (ota updates do not currently work). This is called "dirty flash" and will update your Derpfest version without needing to wipe data or go back to stock.
- To update Derpfest, simply download the Derpfest zip file and in Fastboot Mode, run the command:
fastboot update <filename.zip>
**Do not run the fastboot -w command because a wipe is not needed when updating (dirty flashing) from a previous version of Derpfest.
