I'm trying to backup my phone before making any substantial changes to it. I've done the de la Vega root and made the AT&T APN changes and that's about it. I wanted to use the ADB fastboot commands to load CWM temporarily to do a backup. So I've installed the sdk and downloaded the CWM 22.214.171.124 to the platform tools folder. I found an article on androidcentral which explains how to do this on a GN (which looks a lot like an S3) which instructs on how to use the fastboot boot xxxxxx.img command. I'm stuck before that trying to download the CWM to the phone.
Not sure what I'm doing wrong. the instructions suggest booting into the bootloader by using the ADB reboot bootloader command. That puts it in a "downloading... Do not turn off target" screen which is captioned Odin Mode and on the bottom of the text it says Write Protection Enabled. Did I miss a step with Sudo?
the next step is described as running fastboot devices to see if the computer sees it. This gets no response but the prior reboot command would still work. Finally it ignore the fastboot boot command as it did the fastboot devices command.
Can anyone tell me where I've dropped the ball and what to do?
