Bootloop/ADB/Data Recovery - Phone Not Recognized With Correct Drivers

[UntrustedAlly]

I am trying to recover the data from my old bootlooping LGV20. My drivers are updated. When I plug my current, working LGV20 into the computer, the phone is immediately recognized and the driver is listed as LG v4.2.0, the most current in Device Manager. The phone is labled as its model number in Devices and Printers. When I plug in my old V20 (which has full access to stock recovery and download mode but does not boot) the computer recognizes something is plugged in, but in Device Manager the device doesn't show up. In Devices and Printers the phone shows up, but as "LGE Android Phone".

Summary:

• When a working LGV20 is plugged in, it is recognized and the latest 4.2.0 driver is used.
• When the bootlooping phone is plugged in and completely off, it is only recognized as "LGE Android Phone"
• Not recognized in Recovery mode
• Because of this issue, I cannot use adb on the phone to recover my data.
• The phone is stock, non-rooted, android 7, LG-VS995. I have the usb debugging option in the recovery menu though the phone bootloops when this is selected.
• ADB installed via 15 second installer and SDK.
• "ADB Devices" returns nothing.
• When in Download mode, "Fastboot devices" returns nothing.
• This issue was repeated on a second computer.
• USB 2.0 and 3.0 tried.
• The phone is recognized in LGMobileSupportTool
• In Download mode the phone is recognized as "LGE AndroidNet" in Devices and Printers and as a COM41 port (changed from 7) in Devices and printers.

What do? I'm at a loss and it feels like I've tried everything.

Edit: I've successfully dumped the phone via LGUP, tried flashed a new image, phone is still bootlooping. Is there any way I can browse the userdata dump file?

History of the phone? Did you buy new or used/refurbished? Any water damage? Is the back of the phone still have the water damage indicator? Have you root your device? Did you use cheap brand cables? I'm thinking the device might either be physically damaged somehow or you soft or hard bricked it. I'd check XDA forums instead as they specialize in that there.

Bought brand new, I believe the phone is hardware damaged. No water damage but my dumb *** used 70% isopropyl on it at one point. Not rooted. Good cables, I've tried 3 kinds, and again, the cables work on my current phone. I believe its physical damage as the issue persists with after being reflashed. I made an XDA post, no reply yet.
