OK, this is ridiculous.

I haven't played GH2 since the middle of last week so don't have the patch. Hopefully it's not a mandatory one. I'm not risking it to be honest.

My Xplorer suffered from the broken whammy, I couldn't complete the whammy part of the tutorial, but didn't realise it was because of a hardware fault. Then I saw on Spong that some were DOA.

I followed the instructions here:

Scroll down a bit until you see the better pictures. This worked perfectly for me, your mileage may vary. I am now very wary that I won't be able to play until they release a non-360-buggering patch.

DP, stupid website error O.o

I updated and have played some 10+ hours after it with no issues. I'm guessing it will only happen to some systems.

I haven't had much of a problem to begin with. My Whammy originally did work and then i could only use it if i pushed it back a bit and then pushed it in. When the patch came out, i now have no problem at all.

(Oh and by the way my 360 did break but this was before the patch came out. I was having intermittent problems with my 360 and it just overheated and i could eventually not turn it back on again. No point in getting Microsoft to pick it up as 2 of my works mates had to send theirs back a while ago and it took 3 months for each of them as they did not know where Guernsey, Channel Islands is. Ridiculous. I am using my mates 360 as he's never in to play it.)
