c) Next, plug the Mini-B USB cable back into the debugger.
d) As soon as both LEDs flash quickly, immediately unplug the power cable
from the debugger or remove the screwdriver (within 1 second). If the LEDs
are steady on purple, proceed to the next step. If the LEDs are blue, you did
not perform the action fast enough and must repeat the process starting at
step a).
e) Try to reestablish communication with the MPLAB X IDE or MPLAB IPE. If
successful, the latest firmware is automatically downloaded and the debug-
ger goes through a built-in self-test. When complete, the LEDs are steady on
blue and the debugger is ready for operation.
Refer to Section B.4.2 “Indicator Lights (LEDs)” for more information on LED
modes and bootloader errors.
