How can I use this, sorry I'm new to python and can I use this to debrick my hard brick LG V60?

How can I use this, sorry I'm new to python and can I use this to debrick my hard brick LG V60?

No - sorry. This would let you download the firmware file for your V60.
The extract utility is the only one working right now. I haven't ported my KDZ downloader to the python script quite yet.
If you want your firmware update file, you can let me know, but otherwise right now LGUP is your only way to flash a KDZ, and EDL mode would be the only way to flash the contents within it.

@haise0 ohh man, I've tried everything already but the problem is the firehose programmer for the v60 isn't available yet, I don't think LGUP would recognize my phone in EDL mode and unfortunately for me the phone is hard brick so that's the only way the PC recognizes it

What this python script does is access the LG api and return the firmware download URL based on the device's IMEI, but currently this script can't fetch the firmware of the latest models released by LG I created a page in PHP based in this python script.

V60 ThinQ 5G LMV600VM https://kfhost.net/firmware/lg/model/LMV600VM

@kelisonbessa the thing with my phone is that it is hard brick, download mode doesn't work neither fastboot or ADB the only thing working is EDL mode and as far as I have understood the only way you can restore the software back is using the firehose of the phone with Qfil, but I might be wrong, maybe the software can be restored using other methods.
