Yes, sure. Press the camera button while the phone is off next to the spacebar, and hold this camera/syn button for like 10 seconds. After this take a usb cord and plug it into your computer and still hold down the camera button. You should see a tri colored screen come up and when you see this you need to flash with the original rom. Like if you have T mobile flash it with the T mobile Rom, from the T mobile website. And then once you reflash you can reload 6.1 Rom.
