Rockey4

[toro]

hi
you can see rockey manual for function descripion. rocekys dongle protection logic are different with other traditional dongles. the developer can insert some portions (functions) of his code to dongle in design time , and in run time send parameters to dongle and recieve result of function from dongle. acctually dongle can execute some functions by itself. so patch method can not work for it.
however rockey 4 is very simple and you can guess functions which is in it by some effort. or somtimes even you can do a full search on all possible values as input parametes and create a table for output valuse.
and there are other approach...

i think you are lucky becasue you have rockey4 not rockey5.
