I downloaded CWM for Moto G from http://www.clockworkmod.com/rommanager. My intent was to backup the entire phone, including the ISP's ROM, before rooting or even unlocking the bootloader. I didn't know whether I could avoid unlocking the bootloader, but I was going try backing up without flashing to the device to see if it would let me. I put the phone in fastboot mode by holding down the power button and volume-down for 10 seconds. Then I issued the following from the command line (I'm using cygwin's bash shell, and the directory containing fastboot is in $PATH): $fastboot boot recovery-clockwork-188.8.131.52-falcon.img downloading 'boot.img'... OKAY [ 0.310s] booting... FAILED (remote failure) finished. total time: 0.313s Is this the symptom of not having unlocked the bootloader?
