Disable Driver Signature in Windows (Temporary)

You need to disable the driver signature enforcement in your Windows PC. This process is essential as Windows 8 & 10 only allow drivers which are signed by Microsoft. To install OnePlus Qualcomm drivers which are not signed by Microsoft, we need to temporary disable the Driver signature enforcement. Don’t worry, it won’t harm your Windows OS in any way. 

Step 1. Going forward with this, restart your pc by keeping shift key pressed.

Step 2. One your pc is rebooted you need to select the Troubleshoot option available.

Step 4. This will show you a  set of startup settings that can be easily modified. You’ll find the “Disable driver Signature enforcement” option on No. 7. Press “7” or “F7” on your keyboard.

However, a word of caution while unbricking device your phones. Ensure that you understand risks beforehand. Backup your data (If you’re able to get into the device) from your phone such as your audio, video, photos, etc., to your pc or pen drive or other online storage, when you unbrick your phone.

Unbricking a device erases all the data in it’s memory and provides a fresh software just as you got it when you took it out of the box. Don’t move the device or shake the USB cable during the unbricking procedure which starts when you click the “Start” button. If you disconnect your device during the process, there are very high chances you could permanently brick your OnePlus 6 which could only be repaired via service centre through a hardware change.
