I'm on my 4th Hydro, although this one is Hydro Shore the previous 3 were Hydro Air, and I fought with this issue for months. I've yet to get it to work on any Hydro. I recall reading somewhere that Kyocera Hydro is "blocked" from going into recovery somehow, but I have no idea if that is true. I wouldn't think that would make sense? I just know I am really frustrated that these phones have issues doing something so simple.
Let me know if that works for you guys.
You got me. I've been trying for six hours to get it. Tried every combination I've seen and timed it differently. Nothing. I'm starting to wonder if Recovery Mode is some mythical place.
