You will need the tracking data. This will consist of a .trk file and a .enc file. To properly restore the radio, these files need to be re-installed in the radio for proper tracking and feature data. You will also need the radio code and dsp code if applicable. The tracking and encryption data files are usually auto stored on your hard drive in the ProGrammer software folder called backup. You will need to read the radio info using Radio Maintenance and get the ESN. The ESN will correspond to the data stored in the backup folder.
Perform a radio recovery and when it asks for tracking data, point to the backup folder and look for the ESN.trk file and then do the same for FEATURE.enc. When prompted, load the radio code and DSP code. When recovery is complete, program the personality in the radio prior to cycling power.
