- #define RESET 0 // Use 0 (B0) instead of 10
- #define LED_HB 11 // Use 11 (LED on the Teensy 2.0)
- #define LED_ERR 8 // This won't be used unless you have an LED hooked-up to 8 (D3)
- #define LED_PMODE 7 // This won't be used unless you have an LED hooked-up to 7 (D2)

-And make the changes in the last four lines. If you're using something besides the Teenys 2.0, you'll want to choose something else that makes sense for `LED_HB`. We define `RESET` as `0`/`B0` because that's what's close - if you want to use another pin for some reason, [you can use the pinouts to choose something else](https://www.pjrc.com/teensy/pinout.html).
+## Just the Bootloader File
+
+If you just want to get things back to normal, you can flash only a bootloader from [`util/` folder](https://github.com/qmk/qmk_firmware/tree/master/util), and use your normal process to flash the firmware afterwards. Be sure to flash the correct bootloader for your chip:
+
+* [`atmega32u4`](https://github.com/qmk/qmk_firmware/blob/master/util/bootloader_atmega32u4_1_0_0.hex) - Most keyboards, Planck Rev 1-5, Preonic Rev 1-2
+* [`at90usb1286`](https://github.com/qmk/qmk_firmware/blob/master/util/bootloader_at90usb128x_1_0_1.hex) - Planck Light Rev 1
+
+If you're not sure what your board uses, look in the `rules.mk` file for the keyboard in QMK. The `MCU =` line will have the value you need. It may differ between different versions of the board.
