You've tried the two best methods out there. You may try Windows Device Recovery Tool by pointing to the rom folder (tap on three dots, settings, packages, custom path. Try flashing from a cold boot and have the recovery tool pick up the device before it boots. Try to force it into recovery mode on boot (from off state, press power button and then vol down until you see the exclamation mark). If that still doesn't work you may want to try this on a different PC. If that fails then I'm afraid you have a brick if the phone doesn't boot (not clear whether you are trying to install this rom onto a working phone or a non-working phone).
cheers
If it starts working again when you put the yellow screen back on, it's not a rom problem, it's a bad replacement screen.I appreciate the help and will give WDRT a whirl. My phone works, but I need to replace the screen which has the classic yellow burn mark on the top right. When I do that, the touch screen feature stops working. Someone recommended flashing the ROM to fix that. At this point, the phone is dead to me anyway, so I don't really care if I do permanent damage. If I can repair it I'll sell it on eBay.

Or you get a replacement screen that works. I assume you are referring to this post in which it is suggested to flash the phone with a rom after upgrading the screen. The instructions are for a L535 based on seller notes. I don't see evidence that it will work for the L640XL. There are a number of members here who replaced their screen without this step.
edit1: ok, I just realized that you and the OP from the thread I linked above are the same person and that you are aware of everything related to replacement.
It is not clear from your posts above whether your original screen works or not. You only mention that it doesn't work when you put your replacement in. If your original screen is not working either that is an entirely different story of course.

I get this when I follow the steps you outlined:
Because at this point I don't really care if I totally destroy the phone, I'm going to install the new screen and try flashing it with WDRT just to try. It seems to be my ONLY option at this point.
if you click the three dots bottom right you could try to install a custom/region rom that may be compatible with the phone. You'd have to get that from a different source of course. You point WDRT to the newly created folder with your custom rom.
Anyway, hope this will solve you problem.
