Yesterday, I had flashed Pixel Experience i for OnePlus 7 Pro. Then flash that ROM successfully. Then today, I wanted to go back to the stock ROM. So I used this MSMTool. I have used the MSM tool before with the proper Qualcomm driver. So today, during the flash stock ROM by MSMTool, it showed an error in the middle of the process. Which was related to flashing System.img at 34%. So after 10 minutes of being stuck, I had to remove the phone from the PC. After removing My device has not turned on. It was showing nothing. No charged response, no logo, nothing. Then now when I'm trying to connect it to a PC by cable and pressing volume up and down, Windows says, "USB device not recognized." I've tried many times on different PCs. But it shows the same error. Is there any solution? How can I connect my phone in EDL mode with a PC using Qualcomm Diagnostic?
