thanks for the clarification. i wasn't being lazy, there are several threads that redirect to several other threads each (some of which aren't even about the z2 tablet specifically) and the message tends to get blurred after digging through several pages of threads that may or may not even have bearing on what you're trying to do.
i am assuming that without drm keys it will be impossible to return to stock (at least with working bravia engine and other protected services) would this be true? is there any work around to get these services back after you root, or are they gone forever?
also, my main reasons for wanting root are for removing restrictions on SD card, is there any non-root work arounds for this? (also xposed)
My z2 tablet should be arriving today, I am going to try to use it without root for a while to see if i can mentally deal without having xposed and full access to sdcard, hopefully i can hang, cause i'm not crazy about losing functionality (superfluous or not) forever from a brand new device i just paid lots of money for
also still trying to find clarification on updates, once unlocked & rooted can i just use regular updates or will that break the modified kernal and cause issues? i'm not sure if the modded kernals out there are for the latest version on firmware and how that is handled, all of my rooting experience just comes from flashing new updates of ROMs to my device (like AHRD or Hyperdrive), so i've never dealt with system updates to stock firmware while being rooted and unlocked.
