Thanks for the instuctions.
I received an OTA update to Gingerbread 2.3.4 yesterday. The few times I have tried powering down since then have been successful. Maybe this update resolves the restart problem? Will update here once I have more data.
Verizon just released an OTA update for the Droid 2 to fix the "auto on" problem as it is known. I just downloaded it, the update is to 2.3.4
Everything seems to be working smoothly so far, no issues with my D2 rebooting itself. My camera would not work for a few hours but I do not know if that was related to the update or my phone being old.
