Install /e/OS on a Google - Pixel 7 Pro cheetah

This guide installs /e/OS on your cheetah. Read it through once before you start, so you don’t hit surprises partway in. Downgrading from a newer OS version than the /e/OS build you’re about to install can cause instability or brick some devices — check your current OS version first. Flashing is done at your own risk: /e/OS builds are provided as best effort, without any guarantee, and the /e/OS project takes no responsibility for the consequences.

Requirements

  • Back up your important data to an external storage device — some of the steps below format the phone, wiping any backup left on it.
  • Charge your phone above 50%.
  • Enable adb and fastboot on your PC — setup instructions .
  • Download every file listed in the Downloads section below before you start.
  • Use a real data cable — some cables only charge and can’t transfer data.
  • Enable USB debugging on your device — instructions .
  • Confirm your exact model in the Device Selector : where shown, hover the device name for the supported model number, and check it matches yours exactly.
  • Boot the stock OS at least once and check everything works — SMS, calls, and both over WiFi and LTE if available (some devices need VoLTE/VoWiFi used once on stock to provision IMS). Whatever’s broken on stock stays broken on /e/OS.
Warning: Log out of any accounts (Google, Samsung, Mi Account, etc.) set on the stock ROM before proceeding. Most vendors enable Factory Reset Protection (FRP): after a factory reset, a device that's still signed in will ask for the credentials of that account before it can be used again. Also remove any screen locks.

Downloads for cheetah

Tip: Before installing /e/OS on the Google Pixel 7 Pro cheetah for the first time, install the latest stock OS version 16 build on the device
community /e/OS A16

Each build includes /e/OS Recovery — no separate download needed.

Not sure which one to pick? See official vs. community builds .

  • Before following these instructions please ensure that the device is on the latest Android 16 firmware.

  • If your device is currently using a newer or older version than the required version, please upgrade or downgrade to the required version before proceeding with your /e/OS installation.

  • The required version is Android 16 , which may be lower than the /e/OS version you are about to install - this is not an error! If there are multiple updates of that version (e.g. security updates), make sure to use the latest!

  • If you need to upgrade or downgrade your device, please search online for guides. We are unable to provide specific instructions here and on our support platforms.

Unlocking the bootloader

These steps only need to be run once per device. Unlocking the bootloader will erase all data on your device — make sure anything you want to keep is backed up (see Requirements above). Not sure what unlocking changes on your device? See Bootloader relocking .

Tip: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root.

  1. Enable OEM unlock in the Developer options under device Settings, if present.

  2. Connect your device to your PC via USB.

  3. 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 Down + Power

  4. Once the device is in fastboot mode, verify your PC finds it by typing:

    fastboot devices

  5. Now type the following command to unlock the bootloader:

    fastboot flashing unlock

  6. If the device doesn’t automatically reboot, reboot it. It should now be unlocked.

  7. Since the device resets completely, you will need to re-enable USB debugging to continue.

Flashing additional partitions

This platform requires additional partitions to be flashed for recovery to work properly. The steps to flash the partitions are given below.

The partition files will be available in the /e/OS build or /e/OS recovery zip folders. Look for the file name starting with the partition name. For example, the vbmeta.img file may be named vbmeta-e-x.y-aX-YYYYMMDD123456-channel-codename.img. You can rename it to vbmeta.img if you want to — the part after vbmeta is just an indicator of the build date when it was compiled. If the files are not found in these zip folders, users can download them from the LineageOS wiki install page specific to this device and OS build.

Tip: If you encounter an error such as "No such file or directory" when executing a fastboot flash command, it is because fastboot cannot locate the image file. You can resolve this by either specifying the full path to the file (e.g., C:\Users\YourName\Downloads\boot.img) or by typing the first part of the command followed by a space (fastboot flash boot ) and then dragging and dropping the file directly into the terminal/console window.

  1. First unzip the /e/OS Recovery file linked in the section marked Downloads for cheetah . The following files would show up in the location where you unzipped the contents of the eRecovery zip file

    • boot.img
    • dtbo.img
    • vendor_kernel_boot.img

  2. Next we manually reboot into bootloader or download mode

    • With the device powered off
    • hold Volume Down + Power

  3. Flash the downloaded image files to your device by typing (replace <...> with the actual filenames):

    fastboot flash boot <boot>.img
fastboot flash dtbo <dtbo>.img
fastboot flash vendor_kernel_boot <vendor_kernel_boot>.img

  4. Reboot to bootloader mode

    fastboot reboot bootloader

Installing a custom recovery using fastboot

  1. Connect your device to your PC via USB.

  2. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

    adb reboot bootloader

  3. Once the device is in fastboot mode, verify your PC finds it by typing:

    fastboot devices

  4. Flash a recovery image onto your device

    fastboot flash vendor_boot recoveryfilename.img

    Replace the recoveryfilename with the name of the recovery image you downloaded in the previous section

  5. Manually reboot into recovery mode

  • With the device powered off
  • hold Volume Down + Power and choose Recovery Mode.
Tip: Outdated fastboot releases dropped legacy A/B support, so it might attempt to flash to boot__a / boot__b rather than boot_a / boot_b if you try to flash boot. In this case, you must update fastboot to a release newer than or equal to 31.0.2. Alternatively, you can manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to boot__a, you must flash to boot_a.
