Firmware Downgrade from 1.02.63 to lower versions not possible in RMS1.8

Conditions:
While downgrading DLC version from 1.02.63 to any lower version ( e.g. 1.02.51, 1.02.43), post downgrade when DLC boots up again with lower software version( e.g. 1.02.43) and send TransferComplete inform,  RMS keep sending GetparameterValues request for  mandatory discover parameters of  Cos 1.02.60 (OTA related) . But because DLC (now in software version 1.02.43) doesn't know this parameters, sends fault code 9005  with Invalid ParameterName, and because of this DLC software version never gets updated to the BAC UI and neither DLC gets associated with correct COS.  And it keeps continue thereafter.
