"This is the MetroPCS Zmax I'm talking about. I'm not sure about T-Mobile. Basically if you want to buy a MetroPCS Zmax and root it, make sure that when you go into settings/about phone that the build number is Z970_MetroPCSV1.0.0B06 or Z970_MetroPCSV1.0.0B01
Also, if you have one of these Zmax with either of the above build numbers, don't take an update if you might want to root it in the future.
Build number Z970_MetroPCSV1.0.0B10 seems to be unrootable so far. A new method may become available but that is a big IF. I'm currently trying to find someone who will trade my new zmax for an older one that hasn't been updated or I might just flat out sell it."
