[Windows Phone 7 Q&A, Help & Troubleshooting] VenezuelaDan:
I have been able to unlock my phone before, but now no matter what I do, I just can't seem to get past the ChevronWP7.exe error of not being able to communicate with the phone after I click unlock.

I think I know why. I had been trying to get my device (Samsung Focus) to be able to be seen as a USB storage device (http://xdaforums.com/showthread.php?t=915664) . I had messed with the registry keys until I got the desired effect.

Well a couple of days later my phone's screen would turn off as soon as a call was started and would be inaccessible until the call ended, and also the camera wouldn't start under lock. These problems were unrelated, and frustrated me enough to hard reset my phone. I had jailboken it once before, so I figured, how hard could it be to do it again.

I've followed all of the steps TO THE LETTER (from here: http://xdaforums.com/showthread.php?t=938106, and also here: http://xdaforums.com/showthread.php?t=857127), to no avail.

Here are all the registry values for the Windows Phone USB in my computer, as per the article above.

Please help me understand where the heck I went wrong! Am I missing anything, are there any wrong values? I'm aiming for just being able to unlock at this point. This is driving me insane! :confused:

Thank you for your help.

Edit:

I've checked any and all possible reasons for not being able to unlock, from using TCPView to kill https processes, to editing the hosts file from having the loopback to windows developer server. I have no other ideas other that this registry is messed up. If anyone (so long as they havent messed with the USB storage thing) could just export that whole registry folder:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_045E&PID_04EC&MI_00]

and just post it, that would be more than enough. Thank you again.
