I just read through it, it was ALOT to take in. Pretty incredible, high level stuff - above my head. From what a garnered, they were unable to unbrick. But someone had suggested using a Qualcomm utility of some sort to flash the appropriate ADB driver on their device, but I wasn't able to comprehend exactly what they were suggesting. Any ideas about Qualcomm HS-USB QDLoader 9008 driver or where I can learn more about it?
I'm not very familiar with the process but I know it is used on many different Qualcomm devices. The methods should work for you, the problem is finding the correct files to use, I don't know which files you need or how to go about finding it.
I suggest you research how to use QPST or QFIL and what kinds of files they require, get familiar with how it works, then try finding those types of files for your device based on your model number and the firmware you were running.
Have you seen this?
