So it seems that there are a few that still want to know how to upgrade their Droid X to 2.2.  We’ve all seen the Motorola post attempting to discourage people from using the leaked version of 2.2. … No one cares.  There is always a way to upgrade … Sanctioned or not.

If you can’t wait for Motorola to drop the official 2.2 update (they’ve been wrong about update releases before) and you understand the risk you are taking … then proceed with the following:

** Not responsible if you break/brick your device or if your dog gets diarrhea**

• Download the gift that was released from mydroidworld.com here
• Copy the update.zip file to the root of your sdcard and shut down your Droidx.
• Restart your Droidx in the recovery console … Power+Home until you see the moto logo.
• Once in recovery, press your search button to bring up the recovery options.  Use volume to navigate the menu and the camera to confirm a selection.
• Select apply update.zip and have fun … the update.zip already has flash 10.1 included.

I love these guys.  They were the first to deliver froyo on the moto droid and from what I can tell by this thread that P3Droid made, this just might be a signed zip that your unrooted and stock Droid X can “apply update.zip”.  Forum followers are all indicating that you need to be stock to apply this.  That means to put back that bloatware and undo any custom hackery you applied for custom notification bars and themes.  Now I should be able to get my wife off my back about getting flash installed on her phone. =D
