I know very little about EDL mode, can someone please explain what is happening here.

Device: pixel 3XL

I am trying to recover the device for somebody that decided It was a good idea to attempt to flash a custom rom without backing anything up or doing any research beforehand. They wound up bricking the device, and it is stuck rebooting continuously in edl mode. I know what edl mode is i have absolutely no clue how to use it.

I have already tried to get the phone to boot into fastboot but whatever they did wiped it out entirely, and now it refuses to boot into anything except for edl mode.

I have tried windows and linux with differing errors between the two but there are two errors that I keep getting versions of on both and it's this usb error.

Correct me if I'm wrong, but I'm certainly sure that Qualcomm based Google Pixels require signed, device-specific firehose loaders that aren't publicly available, so you're probably out of luck with this one.
