. There is another thread on this and in it some people are saying that the upgrade disables PKTether and the Debug mode.
They have indeed been reported and some also got rectified later on. Restarting the camera mostly does the trick, or try re-inserting battery first (to be sure the memory is really flushed). Pk_tether is unstable as is, so you can't blame this update. I tried both debug mode and pk_tether and they still work after updating!
