I found a fix. Use super one click. [APP]SuperOneClick v1.5.5 (Root, Unroot, Enable Non-Market App, Get UNLOCK code) - xda-developers http://forum.xda-developers.com/atta...9&d=1289271263 Its done from a computer. Click unroot first if you were previously rooted. If the program looks like it froze just close it reopen and then click root. I too lost the root Z4root had given me and this did the trick.
