I rooted my droid 2 (r2d2 edition) using z4root and i installed a custom rom (Liberty 2.0.1). Im not having any issues but if i needed to take my phone to verizon i know i would have to unroot it. Here is the issue i did not back up my default rom. Is there any way possible i can restore the original rom so i can unroot my device whenever i need to. PLEASE HELP!!! I DONT WANT TO BE STUCK WITH THIS ROM FOR THE REST OF MY TWO YEAR CONTRACT..
