For some reason I don't have the same list oAttachment 2534082f options...
I can't see the pic that you sent but I think you're talking about the APN option. Its OK if you don't have the same list. You can always create them whenever you need them.
I don't have Sprint service on my Nexus 5 but it looks like you will have to flash the file from the first link I sent you. Everyone else with Sprint seem to be doing the same and its working for them. Please read it thoroughly so you don't mess up your phone.
DISCLAIMER: I am not responsible for any damage caused on your phone. I'm just a guy trying to help someone waving an SOS flag. Please don't drown and blame me.
