Please see the ME recovery guide for this:

In case you don't have a Digi development board to perform the recovery procedure for the Digi Connect ME, you may also short pin 18 (MFGI) of the module to GND (e.g. pin 16).
See page 36 and page 50 to determine pin 1 location in the hardware reference manual:
