Steps for those that don't know.
1) You can be rooted an install this. Please use OTA Rootkeeper and protect root before install. It is not necessary to "temp unroot."
2) If you have SS or BS recovery installed that needs to be uninstalled. Simply open the app and click "uninstall recovery." You do not have to delete the app just remove the recovery. You can NOT install this using custom recovery as far as I know, uninstall using stock rom --> SS (or BS) app and click "uninstall recovery"
3) Download the file, then load onto the root of the external SD card.
4) Boot into stock recovery:
To get into stock recovery hold both volume keys while holding power on. Use volume down to scroll through options then volume up (or power button tap can't remember) to select. If you get red triangle don't worry, just hit both volume keys again you should get recovery menu.
5) Select update from .zip, find the Blur.....875.zip you downloaded to the root of SD card and select update from that.
6) Enjoy official JB support.
If you get failed to install side load error 7 or similar you most likely have one of these problems.
1) Edited build.prop previously --> Fix: Get stock build prop (future reference: Always keep copies of anything you change!)
2) You are trying to install over custom recovery or on top of a stock rom but on a custom recovery partition --> Fix: Wipe partitions, reboot into stock, open SS or BS and click "uninstall custom recovery"
3) You froze or removed system apps including bloatware--> Fix: Replace stock apps or unfreeze them.
P.S. Large update it's over 300 mbs. And for those that say "it's only .246" Motorola calls the new update what you are upgrading FROM not to.
