[Google Pixel XL Guides, News, & Discussion] CZ Eddie:
Flashing a new modem is easy and should not cause any issues.

It should be possible to flash any Pixel XL modem on any Pixel XL variant.

If you go to Settings | About Phone, you will see your current build number.

Mine is nof26v

V

. So the modem from my build will be labeled "v_modem.img" in the linked zip below.

I don't know how well or poor a Euro modem will work on North American/Verizon phones.

It is possible the Verizon modems are fine-tuned to work on Verizon networks.

It's also possible a Verizon phone may get better in-city performance with a non-Verizon modem at the expense of fringe network performance.

Modem's are a tossup. Try one and see if you like it better than what you have.

For most people, they should just stick with their current modems.

If you have good service right now then don't bother trying new modems.

1) Install your Google Android driver if you don't already have one:

https://developer.android.com/studio/run/win-usb.html#download

2) Download Google's ADB & Fastboot and extract the files to C:/platform-tools:

https://dl.google.com/android/repository/platform-tools-latest-windows.zip

4) Download the modem you want to C:/platform-tools (or wherever your Google ADB/fastboot folder ended up at).

5) Boot your phone into the bootloader and attach it to your PC.

6) Go to C:/platform-tools and right click any white spot and select option to "Open Command Window Here".

7) Type the command "fastboot flash modem modem.img".

If you get a fastboot error about something not existing, then check this post for workaround:
