Accidentally accepted update, how can I abort before it actually installs? I have been deliberately avoiding the latest Verizon D2G update for a few months now.   It is really annoying that there is no way to make it stop asking me.  But tonight I was tired and my finger slipped and it accidentally accepted instead of delaying 12 more hours.  My phone started to shut down to install but I quickly pulled the battery out.  Now every time the phone boots after about a minute of starting services it apparently remembers it was going to update so it starts shutting down the phone.

I have tried going to updates and manually looking for an update, in the hopes that this would confuse the phone and it would start asking me again if I wanted to update, but in the middle of searching for an update it just suddenly aborted and threw me back to the setting menu, and subsequent attempts just immediately aborted. [edit:I tried this again, this time immediately looking for updates as soon as I could login.  This time it immediately started searching, and continued searching until the auto-shutdown started.] I also tried looking at the processes with a system monitoring app I have but wasn't able to identify a process to kill before it started shutting down - and even if I did I am afraid it might still start updating when I'm not watching later.

Is there any way I can abort the install?  I am afraid to let it actually start installing because I don't know what to expect. Does it offer me a chance to cancel?  If not, I fear I might brick my phone if I pull the battery after it starts to update.

And in case you are wondering, I absolutely will not allow this update because of the risk of the update breaking some obscure feature I depend on.  For another, this is the update that removes the ability to root.  My phone is not rooted, and I really don't have the the time or inclination to root it at the moment (it is another risk I don't want to take) but I won't accept the ability to be removed.

Edit:
The following information is from the adb log:

07-XX XX:31:15.883  1306  1433 I ActivityManager: Start proc com.motorola.Upgrader for broadcast com.motorola.Upgrader/.UpgraderReceiver: pid=2334 uid=1000 gids={3002, 3001, 3003, 1015, 2001, 1007}^M
07-Xx XX:31:15.953  2334  2334 W UpgraderReceiver: !!! INSTALL UPDATE !!!^M

07-XX XX:31:15.961  1306  1340 D ShutdownThread: Notifying thread to start radio shutdown^M


So, it wants to install 4.5.608.A956.Verizon. [update: actually, that can't be right, because that is the version I am already running! ]

Also, the following did not work:

bash-4.1$ ./adb uninstall com.motorola.Upgrader
Failure

bash-4.1$ ./adb shell kill $(./adb shell ps | grep com.motorola.Upgrader | awk '{ print $2 }')
could not kill pid 2379: Operation not permitted


Update:
Well, I am thinking it is looking like maybe the only way to avoid the update is to actually root my phone. :-(
Ok, here is how I solved the problem:

I followed the first part of the directions here: http://oldwiki.cyanogenmod.org/wiki/Motorola_Droid_2_Global:_Full_Update_Guide  to wipe the flash and install older version of the Motorola software. (specifically, section 2.1.1)  Then I upgraded to the version that I was running before the update started attempting to run.
