I unrooted my Droid 1 because it might be going back to Verizon. I booted my Droid 1 into recovery last night and noticed the option "install update.zip from SD Card" was available. this update.zip is the Ultimate Droid 10.0 ROM.
I was tempted to press it to see what would happen but didn't want to risk bricking the phone.
Anyone know what would happen if I install?
