Hardbricked, please help. - OnePlus 8T Questions & Answers

I tried flashing Nameless A12 rom over NA OOS 11 after successfully downgrading from OOS A12. However, now I am in crashdump mode and cannot access even the bootloader. I downloaded the files from the XDA forum but MSMTool doesn't recognize my phone. I think I have the correct drivers installed because I can see my device in the device manager list as Qualcomm HS QDLoader but there's a small yellow exclamation mark under it. Does that signify anything? Someone please help.
Device: oneplus 8T indian version

Try reinstalling the Qualcomm driver.

Hardbricked OnePlus One Doesn't Get Recognized by RestoreTool

Hi all,
I have a OnePlus One that's hardbricked (it doesn't show any forms of life).
I followed this guide, but I'm stuck. I installed QPST Drivers, and Qualcomm 2012 Drivers (although after installing this one, I get a message stating that the newest drivers are already installed.).
At the moment, my device is recognized in device manager as "Qualcomm HS-USB- QDLoader 9008 (COM10)" and sometimes it doesn't get recognized at all. The device manager will then say "unknown device".
When the device is recognized as "Qualcomm HS-USB- QDLoader 9008 (COM10)", it doesn't get recognized by the OnePlusRestoreTool (even if I run it in administrator mode).
I'm using Windows 7.
Could any of you perhaps help me find a solution?
Thanks in advance!
Robert

Use this to update your download your drivers and make sure they are up to date by going into windows update and checking if you have any Qualcomm drivers updates in the optional updates. https://www.mediafire.com/file/emfun9l7a9unld5/OnePlus_USB_Drivers_Setup.rar/file

If you got detected the device under Qualcomm HS-USB 9008, then your device entered to EDL mode. Check well, what the error was, pay attention to the connection, that device get attached permanently during the flashing session.
