Problem with enabling AWS on S4 I337M Please help

Hello,

I have unlocked S4 I337M and trying to enable AWS. I have done this with my other s4 and it worked perfectly fine. But this phone when switch to RNDIS+DM+Modem or any other option other than MTP my computer doesn't find the driver so I cant go on to next step. I installed Kies3 still my windows cant find the phone if it isn't on MTP. I don't know what to do. Any ideas?
Thanks
