[Q] topic

Hi, I hope I'm not breaking any rules here.

I'll make it short.
I have a new i337 with 4.4.2 AT&T rom. It has a two major problems : First there is no mobile data icon in the notification panel (which I read was AT&T fault) and the second problem is the WIFI doesn't connect automatically or remember any network I was connected before. I need to put my WIFI password every time I want to connect.
I thought about installing an international i9505 STOCK ROM on it but I cant. I keep getting a failed message with odin.
The reason i'm thinking on putting an international i9505 STOCK ROM on it is mainly solving those two problems I mentioned before and because I don't live in the USA or in CAnda/America in general.
What can I do in order to install an international i9505 STOCK ROM on mi i337?
Thanks :)

this is what i get with odin:
