I allowed my phone to install the 4.5.608.A956.Verizon.en.US OTA update this morning. As I expected, it patched the phone so that Titanium Backup could not get root status. Disappointingly, it also apparently patched the exploit used by the Motorola OneClickRoot script. When I ran that script, it claimed to have successfully rooted the phone, but had not actually done so, as apps such as Titanium Backup report that they are unable to get root status. I also tried Z4Root, which hangs indefinitely when you try to get permanent root.
Does anyone know of a work-around, or will I just have to wait for someone to find out a new technique?
