I'm in the process of trying to root my phone for the first time (on a Mac, not PC) and so far things have been going well, until I got to the section about pushing the recovery image onto the phone. I'm using the 1.2.3 recovery image, and when I try entering the command in Terminal it keeps saying the file is not found. I've made sure the file name is exactly correct, its placed in the SDK tools folder, and debugging mode is on (made sure to only turn it on once the phone was plugged in, as per instructions). I've tried re-downloading the recovery file and it hasn't helped. I'm very new to this process and don't really know what else to try. Does anyone have any suggestions?
