Late response here, but unfortunately, I can't do the "Instead..." because the restart button did just what it said. It restarted and booted the new update. Problem is, since I didn't have the option of downloading the OTA then installing Magisk to the inactive slot before rebooting, I lost root. Even bigger problem is now the phone is not recognized by a PC to use adb/fastboot commands. Tried 3 different PCs and multiple cables, and the PC does nothing. The phone screen flashes and the phone starts charging, but USB preferences notification does not show to change to data transfer mode. I can manually open USB preferences, but all options are grayed out. Changing default USB mode doesn't do anything. It's like it's attached to a charger, not a PC. I even did a factory reset and it's still not recognized. Not sure what I can do to regain root at this point.

The post you replied to is out dated. The instructions in the OP are usually up to date.

Did you install the pixel driver's on your computer?

What part is outdated? The procedure in the post I replied to and in the OP are the same: Download and install OTA, use Magisk to install to inactive slot before reboot. I only see reboot option. Regardless, the more pressing issue is I cannot connect to PC to push root via fastboot, so I'm stuck with a functional phone but one that I can no longer re-root. How do I install/update driver if the computer doesn't even see a USB device was connected?

Right, that's what I'm saying...those instructions say "open Device Manager, expand the Portable Devices section, right-click on the connected device name and select Update Driver Software". None of the PCs I've tried see anything connected, so I can't do this. When I connect different Android phones using the same cable and port, the PC sees a device connected and the phone sees that it is connected to a PC, so I believe it is a phone problem.

Have you went into the Developer Options and under the "Networking" section, look for Default USB Configuration and change it to File Transfer/Android Auto?

Yep, tried it. I can slide the slider and pick a connection mode, but it doesn't make a difference. Similar with manually finding USB preferences. It doesn't recognize a data connection, so it's grayed out exactly the same as it is when it's plugged into a charger.

          • If you hid the Magisk app, the default name for a hidden Magisk app is settings.
          • If you changed the hidden name to something else and have forgotten it. Use TB checker to find the name of the hidden Magisk Manager:
            1. Open the TB Checker app
            2. Tap Run Xposed check
            3. Scroll down to Magisk Random Package Name: to see Magisk's hidden name.

    Provided you are not on Verizon:
    Try reinstalling the stock boot.img from the update, flash the OTA, or perform another clean install. After first boot and performing any necessary setup (if clean install), power off phone, remove sim card, reboot. Creat a new patched boot.img, install it and reboot. Turn phone off, reinstall sim card, reboot as normal. Should fix the issue. Make sure you are using the latest magisk (I prefer stable of canary personally but it's your call).
    If you are on verizon, do not install the April update in this thread, as it is stated "All carriers EXCEPT Verizon."

    However, there is an OTA update on the official frimware website that does work on Verizon. I just flashed it myself. Maybe Homeboy76 could update thread?

    :( Do not repeat do not follow these instructions. The information is only partially correct. :(

    I just checked the Factory image and the OTA image pages the only change was the All carriers EXCEPT Verizon has been removed from the images description.

    The OP has been updated to reflect the change.

    These images work on Verizon Pixel 4a 5g phones.

    Uninstalling and reinstalling the Magisk Manager apps should have fixed the superuser and module buttons greyed out problem.

    Maybe @badabing2003 can help you use the Pixel Flasher tool to fix the superuser and module buttons greyed out problem.

    This is typically due to multiple Magisk managers being installed, if at any point, Magisk Manager was hidden, and then another Magisk manager was installed, you'd face issues as this.
    @dadnammit you should first do is, uninstall all Magisk managers, hopefully you can find the hidden one, or at least you know the package name, if you did not rename the application when you hid, then it should be named settings.
    If you have already applied patched boot, then reboot and just install Magisk Manager. and it should detect root.
    You can confirm that you're rooted by doing
    Code: 
    adb shell
su
    if you get su, you're rooted.

    If you are on stock, then just install Magisk Manager and flash the patched boot.
    Whatever you do make sure you only have a single instance of Magisk manager.
