7T Android ADB Fastboot Driver Issue on Windows

[raskulous]

Good day everyone. I'm trying to get my bootloader unlocked to install TWRP, but I cannot seem to get the fastboot drivers to recognize my device when I'm in the fastboot bootloader. It works fine when the phone is booted normally, but once it goes to fastboot, it's no longer recognizable.

I've tried installing both the oneplus drivers, as well as the google usb_drivers

My phone is a OnePlus 7T on Andriod 10, any help would be appreciated.

I had a similar issue, yesterday. This was due to me being too excited to unlock my bootloader. I fixed the issue with the below:

After you get your phone up and running, uninstall that ADB driver from Device Manager, then connect your phone to your PC and enable USB debugging. This will fix the MTP issue and install the proper ADB/Fastboot Drivers.

I tried that out, no change.

I have OEM Unlocking enabled, USB debugging on, and the USB mode set to file transfer.

Try manually updating the driver with the Nexus 4 ADB driver (should say universal in the description).

I tried that, along with the normal google drivers too, and it takes away the exclamation point in the device manager window, and changes it to a question mark.. but I still can't see the device with 'adb devices'

When you check the driver properties do they match what's in the attached image?

No, this is what I get after installing the "Composite ADB" driver from google.

Have you tried to uninstall AND delete all android/android usb drivers, then reinstall oneplus drivers? https://drive.google.com/file/d/1mUz8Y3_WPce1v3IBLOcVi6unFGRztx_o/view?usp=sharing
