Injecting the Sprint files from 5.10.1 into 5.11.0 did the trick. Thanks.since we have no real sprint testers anymore for the htc10:
can you take the 5.10 rom and take the /additions/carriers/Sprint files and replace them on the 5.11 zip.
Just take a 7zip for example. open both zips and drag&drop the whole sprint folder to the other zip.
