 The OpenPilot bootloader code also allows the remaining section of flash to be reconfigured and re-flashed by the
 OpenPilot Ground Station (GCS) via USB without requiring a USB to uart adapter.
 
+# Restoring OpenPilot bootloader
+
+If you have a JLink debugger, you can use JLinkExe to flash the open pilot bootloader.
+
+1. Run JLinkExe `/Applications/SEGGER/JLink/JLinkExe`
+2. `device STM32F103CB`
+3. `r`
+4. `h`
+5. `loadbin opbl.bin, 0x08000000`
+6. `q`
+7. Re-plug CC3D.
