I had my droid X rooted on froyo before the 2.3 firmware came out. After the update went thru, my device was no longer rooted, but superuser was still there. However, when trying to re-root, manually or using z4, it will state that it has re-rooted the phone, reboot and seem fine, but it isn't rooted. I have read this is due to having the old superuser in there, however, I am un-able to re-root to remove it (this is the solution I keep finding when looking for a way to remove the current superuser) I have wiped the system multiple times trying to get it back to stock and remove the superuser, but that has done nothing to help the re-rooting process. I have tried going thru the terminal to mount the file system as r/w, but continually I am denied. I found a forum posting about using RSD lite to flash the phone using a downloaded sbf file, but I'd like to see if there are any other options before I resort to that... any help would be GREATLY appreciated!
