Hmm Leaks eh.?, tried that with 10.3.1.2267 using an Auto-loader. I only did so as I ended up with a BNIB Z30 after my first had Mic issues and when I restored from a backup...lost all Android Apps. So I used the Auto-loader and it soft bricked my Z30... I think I can wait...for a while. Too big a PIT(_i_) to wipe/reload/get apps/fix contacts etc...
