pplz!!! please!! im going to kill myself i took 6210 phone as is has to be! connected everything as on the schematic, but phone says HEADSET mode!!! checked it hundres times! it's wont go into dlr3 mode

the stupidity is like i remeber many years ago (10 or so) i DID this circuit and this worked fine!!! what can be the problem now???!!!
i have switched 15K resistor with variable one, to check every mode the phone supports, 200K i took. and phone just selects between CAR and HEADSET. what the resistor i have to use to make it it DLR3 mode?
just one step before i gonna to develop mine system when im connecting straight to buttons and manipulate the phone with it. but so it's impossible to receive SMSes.
what it can be??? please1111
