There is a hidden diagnostic mode on the Pixel 6 often confused with EDL because it exposes COM ports.
Steps to Enter Diagnostic Mode:
Because EDL is difficult to access, it should only be used as a last resort. You might consider EDL if:
Important: If your Pixel 6 still boots into Fastboot (Power + Volume Down), do not use EDL. You can fix your phone 100% of the time using Google’s official fastboot commands or the Android Flash Tool. EDL is strictly for "black screen of death" scenarios. pixel 6 edl mode

Since you cannot use EDL flashing tools, here is how you recover a Pixel 6.
While the Pixel 6 shares some hardware behaviors with Qualcomm devices, its Google Tensor architecture and locked-down security make true "EDL Mode" recovery much harder than on other Android phones. There is a hidden diagnostic mode on the
Pro Tip: Always ensure your bootloader is unlocked before attempting any major flashing or rooting. An unlocked bootloader is your safety net, allowing you to flash factory images even if the OS is corrupted.

If you are a tinkerer, treat the Pixel 6 differently than older Nexus or Pixel phones. A corrupted bootloader on a Pixel 6 is not a minor inconvenience; it is likely a trip to the repair shop. Because EDL is difficult to access, it should
Pro tip for developers: If you are experimenting with custom ROMs on the Pixel 6, never flash an untested bootloader. Always flash the boot.img and vbmeta.img first. And ensure you have a working Fastboot connection before rebooting. Because once you cross the line into a hard brick, EDL won’t save you—only an authorized Google service center can.
