I have done this on Windows 10/11 with the 8 Pro, 8T, and 9 Pro personally.
Other members have had success with the OP5T, OP6T, OP7P, OP7T, OP8 and even a OP1 for @mawil1013After fighting this for about an hour, and trying everything I could think of, this was the only way I could get my T-Mobile 8T to show up while in fastboot mode.
I tried the below, and probably more...
I tried the below, and probably more...
- Ensuring I had the latest fastboot version
- Manually installing the bootloader driver from googles SDK
- Several restarts
- Just installing OnePlus' driver that come on the phone per-installed
To fix the issue, we are going to disable driver signing enforcement in Windows and then install the Unsigned OnePlus drivers.
- Install the OnePlus drivers that are included with your phone.
- They should show up as CD Drive: OnePlus Drivers when you just connect your phone to your computer.
- I'm sure you can find the installation package somewhere online, but I don't have a good download source so I am not going to give out random links.
- This will create a directory containing the USB driver. This will most likely be
- C:\Program Files (x86)\OnePlus USB Drivers
- In that folder there is a driver, but both when installed using the installer incuded with my phone, and a downloaded version, I ran into...
- The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering.
- To get around this we are going to disabled signed drivers on windows.
- Select the “Start” button.
- Type “startup”.
- Select “Change advanced startup settings“.
- Select “Restart now” under the “Advanced startup” area.
- Once presented with the Advanced options select...
- “Troubleshoot“ --> “Advanced Options“ --> “Startup Options“ --> “Restart“
- After that, a menu will appear where you can press “7” on your keyboard to choose “Disable driver signing enforcement“.
- Now Device Driver Signing should be disabled, allowing you to install any driver until you reboot, meaning we can install our unsigned OnePlus driver.
- Pop open Device Manager
- You can press windows + x to bring up a menu, then you can press m or select device manager for quick access
- Boot your device into fastboot mode.
- This should cause it to show up in device manager as "Andriod", with a yellow triangle
- In device manager right click the "android" device
- Then press the following options
- Update driver --> Browse my computer --> Let me pick --> Have Disk
- Navigate to the folder from earlier: C:\Program Files (x86)\OnePlus USB Drivers
- Select OnePlus_android_winusb.inf and click okay
- After that, OnePlus Android Bootloader interface should be selected. Go ahead and install it.
- Pop open Device Manager
Congrats! Your device should start showing up in fast boot mode.
