Hi im new here, and was looking at another thread about rooting, ive thought about for some time and never got around to it. So I was following all the step and before I rooted I went to do a Nandroid backup. So I power down my phone, hold volume up + power button, phone comes on, little green guys, then I get a pic of a phone with a red exclamation point inside a red triangle. When I hate volume up + power again I get system recovery screen and at the bottom it says E:Can't open /cache/recovery/command. Now im not rooted and I have the 2.1 OTA that I manually installed when it came out, and installed without any problems. Now im just confused and have no idea what wrong with my phone. Phone works fine though when I boot up as normal.
