In this work we present a search for $^{77}$Ge decays in the full GERDA Phase II data set. A delayed coincidence method was employed to identify the decay of $^{77}$Ge via the isomeric state of $^{77}$As (9/2$^+$, 475 keV, ${T_{1/2} = 114}\\,\\mu $s, $^{77\\mathrm{m}}$As). New digital signal processing methods were employed to select and analyze pile-up signals.
