How to upgrade with Devo 12S

Thnx alot so to add hardware sound module its just a hardware from here to flashbit with dfuse or i must do modifications on tx externaly?
Bindi g dsm2/dsms with devo 12s is like binding devo receiver or its different?

Thnx in advance

Thank you so much

I have done the upgrade and after i tryed to bind a spektrum dsmx receiver with telemetry(AR6600T) 6ch and change protocol to dsmx then channels i changed to 6 then code i entered 112233 just for testing and insert a servo to elevator,but was not responding up and down move just left right of aileron stick(mode2) why?also suddenly the devo 12s entered in usb mode!!!
What is wrong maybe there was something i missed?

Thnx alot my friend for all your assistant,i have done what you said and my tx now switch on normaly,ill try to bind it as you sugest me and see what happens.
Something else that i have a difficlulty its when im going to setup i.e a plane hit on icon and is coming a page with mix then other page model setup where is also the bind option.now i would like to know where i can go to setup actually my plane as expo dual rates ?i found something but there is option 1 to 1 then expo dr and some other that cant understand what is it.and also how i can add an icon on main page just for easier way instead of searching in the menu.Is it possible to add more icons of planes in the folder and what type of image and in wich folder.also how i can disable some switches that i dont use and how i can setup the throtle cut?

Dear Vlad sorry again but im in the middle after upgrade the last firmware that you have suggested me.I cant use my devo 12s as i cant setup my new planes,first i cant find where and how i can settup throtle cut with hold switch,expo dr i found them its ok.then i cant calibrate right the throtle dont know why.it starts from -100 up to +100 but starts zero from half throtle and up why?please i would be very obliged if you could help me on these matters so i can make work the tx 100%.And a last thing,i tryed to import some of my plane fotos in BMP version after convertered them from jpg and drop them in the right folder but in the tx menu there are just the default not mine why?
Pls as i cant use my tx and cant fly tomorrow morning at the airfield help me correct these 2-3 things and i would not bother you again
