I was finally able to get the intraops tool on my htc work as in the initial description, however I had to use InteropToolsApp_beta_1.7_0.0.157.0_arm . the older and newer versions would get hung up when accessing "platform". This version shows up as an app rather than in settings. I followed the directions otherwise and updated to 14393.67 . Then after changing in settings to allow windows preview again, I was able to get the 14393.105 update and this is running very well. camera is working. I still have phone id set to 735, haven't changed back yet. pretty happy now.
