  4. Install/Update Factory Image keep or wipe data

    • Important Note(s):
      1. When doing a major upgrade i.e., Android 10 (Q) to Android 11 (R): I recommend doing a clean install. What is a clean install?:
        • Doing a Factory reset prior to installing, major, update.
        • Using flash-all.bat file without removing the -w.
      2. Always verify you have the latest version of SDK Platform-Tools installed on your computer before installing the Factory Image: Pixel 4 XL - coral.
      3. If your phone is rooted and you have Modules installed and you want to 'Keep Data', remove them before you install the Factory Image:
        Why? Some Modules need to be updated before use with a new Factory/OTA image because (sometime) Google makes changes to Factory/OTA images that break the Modules
        .
      4. How to remove Magisk: Open Magisk App ==> Tap Uninstall == Tap Restore Images.
      5. If you get an error:when flashing the Factory image, try one of these options:
        • Change the USB port to a non charging USB port.
        • Change the USB cord to one that doesn't have the blue color head or use a USB C to C cable.
        • Change Computers.
    • Backup your data
    • Download the latest Factory Image: Pixel 4 XL - coral to your Computer.
    • Extract the factory Image to a folder.
    • Keep Data

      1. Open the folder you extracted the Factory Image to and Edit the flash-all.bat file with a file editor i.e. Notepad. Remove -w from this command: fastboot -w update image-coral-aa9a.999999.999.zip
        Note: If you do not remove the -w your data and internal storage will be wiped.
      2. After, you have edited the flash-all.bat file. Copy/Move these files to the Platform-tools folder:
        • bootloader-coral-....img
        • flash-all.bat
        • image-coral-....zip
        • radio-coral-....img
      3. Open a Command Prompt on your computer in the Platform-tools folder ==> Boot fastboot mode on your phone ==> Connect the phone to the Computer.==> At the prompt type: flash-all and press enter.
      4. Note: During the flashing you may notice the phone is in fastbootd mode that is a normal for Android 10 (Q).
      5. System will reboot when flashing is complete.
      6. Do #7 or #8 to root/reroot.
    • Wipe Data

      1. Open the folder you extracted the Factory Image to and View the flash-all.bat file with a file editor i.e. Notepad. Verify the file has the -w in this command: fastboot -w update image-crosshatch-aa9a.999999.999.zip
        Note: This will wipe your data and internal storage.
      2. Copy/Move these files to the Platform-tools folder:
        • bootloader-coral-....img

      • Important Note(s):
        1. When doing a major upgrade i.e., Android 10 (Q) to Android 11 (R): I recommend doing a clean install. What is a clean install?:
          • Doing a Factory reset prior to installing, major, update.
          • Using flash-all.bat file without removing the -w.
        2. Always verify you have the latest version of SDK Platform-Tools installed on your computer before installing the Factory Image: Pixel 4 XL - coral.
        3. If your phone is rooted and you have Modules installed and you want to 'Keep Data', remove them before you install the Factory Image:
          Why? Some Modules need to be updated before use with a new Factory/OTA image because (sometime) Google makes changes to Factory/OTA images that break the Modules
          .
        4. How to remove Magisk: Open Magisk App ==> Tap Uninstall == Tap Restore Images.
        5. If you get an error:when flashing the Factory image, try one of these options:
          • Change the USB port to a non charging USB port.
          • Change the USB cord to one that doesn't have the blue color head or use a USB C to C cable.
          • Change Computers.
      • Backup your data
      • Download the latest Factory Image: Pixel 4 XL - coral to your Computer.
      • Extract the factory Image to a folder.
      • Keep Data

        1. Open the folder you extracted the Factory Image to and Edit the flash-all.bat file with a file editor i.e. Notepad. Remove -w from this command: fastboot -w update image-coral-aa9a.999999.999.zip
          Note: If you do not remove the -w your data and internal storage will be wiped.
        2. After, you have edited the flash-all.bat file. Copy/Move these files to the Platform-tools folder:
          • bootloader-coral-....img
          • flash-all.bat
          • image-coral-....zip
          • radio-coral-....img
        3. Open a Command Prompt on your computer in the Platform-tools folder ==> Boot fastboot mode on your phone ==> Connect the phone to the Computer.==> At the prompt type: flash-all and press enter.
        4. Note: During the flashing you may notice the phone is in fastbootd mode that is a normal for Android 10 (Q).
        5. System will reboot when flashing is complete.
        6. Do #7 or #8 to root/reroot.
      • Wipe Data

        1. Open the folder you extracted the Factory Image to and View the flash-all.bat file with a file editor i.e. Notepad. Verify the file has the -w in this command: fastboot -w update image-crosshatch-aa9a.999999.999.zip
          Note: This will wipe your data and internal storage.
        2. Copy/Move these files to the Platform-tools folder:
          • bootloader-coral-....img
          • flash-all.bat

    My apologies. I certainly was not trying to impugn your knowledge base or technique. I simply missed the SS for the CMD is all. I really don't know what the problem could be since both of the commands that have been discussed, work for myself and others. I suppose the work around would be to fastboot the boot.img, switch slots, then fastboot it again. However, I'm sure that won't mitigate your frustration as to why it doesn't work. I do like the "Vincent Price" retaliation technique though!

    done!!!!!!!!!!!! thank god thank you sir thank you very much that worked

    Not really if you use factory images.

    Hi, is everyone still passing safetynet?
    No! :(
    I've just rooted my new Pixel4XL, the process went smoothly, but not passing Safety-net (i.e. ctsProfile is false)
    You're not alone!. :(
    Seems Google has reapplied their attestation shenanigans again. Likely a harbinger of things yet to come! ??
    Yup!. :eek:

    A temporary fix for passing safetynet is this Magisk module. I use the module's name as the link name for the post: hardwareoff_1.1.zip
