Hi.

I was following this tutorial: https://forum.xda-developers.com/oneplus-6t/how-to/guide-sim-bootloader-unlock-root-t3921795

It worked fine, and I booted into the international ROM. After that, I set up developer mode, and enabled OEM Unlocking as well as USB Debugging. I then ran the command `adb reboot fastboot` (note: fastboot, not bootloader) on accident. Now, the device has a black screen and is not responding to the power on button, nor any VolUP + Power combinations. When connecting the device to my PC, I here the windows device connected sound. For a while, the device showed up on the MSM tool, but when trying to flash it, it would hang on the first part, with status as Waiting for Device. Now, it doesnt show up in MSM tool.

Can anyone help?

Thanks

(Willing to go back to TMobile version)
