How to flash or close the bootloader on open pixel 5a ? g.co/ABH

[billyedit]

Hi I've a pixel5, it was reset to V11 software for compatibility with my son's medical device. Now with added security the app wont work because the bootlaoder is open. When I boot it say sits unlocked and to visit g.co/ABH
I've tried but cannot get it closed
When I go to fastboot I get the 'no command'.. on tring to flash it allows me to see the device and reboot the bootloader BUT then it will not respond to the cmd fastboot devices. when I try fastboot flashing lock it just says <waiting for device>

Any help? !

I'm confused about "sits unlocked" and if this means you're stuck on the unlocked bootloader warning screen. If the phone hangs you're better off keeping the bootloader unlocked until that problem is sorted out. If it's starting, on the other hand...

Waiting for device means fastboot isn't communicating with the phone. Could be USB drivers. But if you flashed Android 11 from the same computer, drivers were working then, right?

In Developer options make sure USB debugging is enabled. While there, and while the bootloader is still unlocked, make sure OEM unlock is in the On position; it will flip back to Off when the bootloader is locked again.

Use Platform Tools 33.0.3 when trouble shooting USB to avoid trouble shooting Platform Tools 34.x.x.

As long as you get serial number output from commands adb devices and fastboot devices, fastboot flashing lock should work to re-lock the bootloader. Remember to finalize locking with the phone buttons.
