Well my friend I had went through multiple calls to sprint customer service some of them were 3-5 hours of me complaining!!!! Then I also e mailed HTC and google wallet support multiple times about the issue and HTC/phandroid mods were the most helpful in forcing/helping me get sprint to give me a new device!! Although sprint was very reluctant in helping me for the same reason as you but with phandroid and HTC on my side it helped a lot I'm sure!!
But be careful because I spent 5 hours on the phone with sprint still demanding a new device and they told me once my 14 days is up then I'd Haveto pay the insurance premium or be stuck with a defective device as far as google wallet was concerned and so I hadto raise h e double hockey sticks and blah blah blah...and they would not extend the 14 days for no reason!!! So I suggest you email HTC about this issue like I did, wait for a rep to call you over the phone, Express your anger carefully but forcefully, and if the HTC rep you talk to calls sprint for you like he did for me, he should be able to help!! My local sprint corp store did a swap for me after a week and a half of battling with sprint customer service which was no help and google which was no help... Google only offered me a galaxy nexus in exchange for my defective 2 day old device!!
But when I went into the corporate store they asked if they can do a factory reset first to test it and see if that will fix the issue first and made me sign a waiver...I did that and they did the reset and once they saw that didn't fix the issue they were more than happy to hook me up with a brand new device straight from the back room!!!
So I'd suggest taking that route email HTC and you can always try sprint but there no help atleast not for me they weren't but the local corporate store with HTC on my side was very helpful so try that route my friend cause sprint customer service is nothing but people who have no clue or care!! They told me to do this, do that I did and nothing worked...drove to a repair center and the rep there had no idea what to do or how to fix it.. so I wasted my time and gas!! So trust me try what I did and if no luck il pm you with my contact info if you'd like for more specific details on what I did so this post isn't already longer then it is now lol good luck my friend !!!!
And I'm not sure what it means but I just noticed google wallet has an update and the update features ** New form factors for new devices!? What does that mean? Because since my whole ordeal with google wallet since I still have the same gmail I had with my old evo 4g LTE that became defective I have been very hesitant to activate wallet using the same email so I still havent activated wallet on my new phone until I know for sure 100% I'm safe to use the same gmail address as before when my google wallet account became bricked over a factory reset....
