New Mix 2: No 2g And 3g Data

[_Pred]

Hey guys,

I've flashed the 8.4.26 on my Mix 2, but I have the problem, that on 2g and 3g networks I don't get mobile data, only calls are possible.

Thanks
Peter

Edit : APN is definitely correct, and changing the settings what Network should be prefered indnthe settings didnt help either.
