Pixelmod is a custom ROM for the Pixel 5 (redfin) devices, based on AOSP (Android Open Source Project) with small modification to make it usable. By this, it excludes some of the default apps and includes some other prebuilts apps like F-Droid. It's a personal project to make AOSP usable for my needs and to make the compilation of AOSP with custom changes easier.

Use at your own risk.

Modifications

  • Remove Browser2 (WebViewShell)
  • Remove Camera2
  • Remove QuickSearchBox
  • Add F-Droid Prebuilt APK
  • Remove Quick Search from Home Screen

Install

You can always obtain the latest pre-built ROM at the Release Page.

Unlock Phone

To enable OEM unlocking on the device:

  • In Settings, tap About phone, then tap Build number seven times.
  • When you see the message You are a developer, tap the back button.
  • Tap Developer options and enable OEM unlocking and USB debugging.

Turn off the phone, press and hold Volume Down, then press and hold Power.
