Cannot access Engineer mode i9505
I try to get into the Engineer Mode for some time by all possible means, however, I came across a wall! Unable to enter it via MobileUncle tool there by any other existing app, codes *#*#3646633#*#* and "*#197328640#" do not work too.
I tried several ROMs, several modem but it's always the same story.
Would you know a solution in order to enter the engineer mode?
