I did it, but again the same problem.
Nothing happens. Just again freeze on start.What happens if you try pushing power and volume up/down at the same time? It should turn the unit off and then try powering it on again. Mine froze a couple of times early on and I did this. Seemed to fix it. I would also love to know how to get Honeycomb on my wm8650, but the many different directions I've ready are so confusing to me.
I wouldn't waste any time trying to fix the stock ROM. Get the uberoid version (check link in my sig - you'll need to register first) and put it on a sd card and then install it.
