Montecrypto, first I wish you a Happy New Year.
While searching for a possibility to downgrade the firmware of by G1-model DS-2CD2785FWD-ISZ resp. DS-2CD2185FWD-IS from 5.5.0 to 5.4.6 resp. 5.4.5, I came across some communications of yours involving a "hikpack"-program. Would that also work for my G1-models? If yes, where could I get the newest version of "hikpack" ? Is there any alternative way?
