I recently bought a RAZR and quickly rooted it, then found my old fascinate and activated it to get the update (Not worth it). The activation killed my sim card and I need to unroot my phone to get the new one in and activate the Razr. I rooted my phone using the droidrazrroot method, and the unroot guide provided with it has failed to work. I'm pretty sure I have the drivers, but I'm wondering if I need to use the updated DroidRAZRUtility.zip or if there is any other method available that won't make my phone less usable.
