I have an unlocked pixel. I just wanna make sure nothing will mess up if I try to flash an image through wugz

I guess wugz is a toolkit right? I'm not sure why you'd need to use anything other than the bootloader menu to flash a factory image. Extract the image you want, in bl menu (on the computer) just type flash-all if you're on Windows, walk away when it starts and come back in 10 minutes. Done.

That's what I was thinking. And the fact that a full wipe is desired makes it even easier.

Yes wugz is a root toolkit but it also let's you restore your phone with whatever version of Android you want, and also downloads the image for you. I haven't tried doing it through the bootloader
Are you familiar with flashing Google factory images? If not, @CZ Eddie has a nice tutorial in the guides sub-forum.

I do that through ADB right?

No, you do it while in the bootloader menu from the computer. You just need to make sure your device is recognized in bootloader mode on the computer with the command fastboot devices. It should show up. Then flash to your hearts content. Just download and extract the correct image to the correct folder on the computer.

i'm not having any luck with adb. It doesn't show my device in fastboot OR recovery. When the phone is booted up, adb works fine. Can I just put the image zip on the phone and install through revovery?

No I think you should properly learn how to use fastboot and adb before continuing any further.

What fastboot version are you currently using.
What output do you get when you type fastboot devices with your device in the bl menu. Let's figure out you're fastboot issues first and then worry about flashing the image(which will be the easy part).

Wise words. Not replying to the OP so hopefully he reads down a bit. It looks like his drivers are not working, i.e. the fastboot ones since he can adb. If he's on Windows then device manager should show an exclamation mark or unknown device. There is a fastboot installation, let me take a look see if I can find it. Ok here ya go. https://www.androidusbdrivers.com/google-pixel-usb-drivers/ I actually didn't need to do that exact procedure but I've been fastbooting for some time.

To the OP. You need to get 'fastboot devices' command to show your device when connected via usb to your computer and in bootloader mode. Once it sees the device the rest is child's play.

I can get the phone to show on the computer in adb when the phone is booted up, but it won't show while in fastboot. I use the same command 'adb devices' when the phone is booted up and also in fastboot. I looked through my device manager and there's no exclamation points anywhere on both computers that I've tried

You need to type "fastboot devices" when in the bootloader.
