I'm trying to enter CWM recovery so that I can back up my ROM.
While rooting my S3 I could enter CWM using the instructions I was following at the time (which I no longer have around).
Since then I've used the built-in encryption feature to encrypt the device.
Now when I try to press simultaneously the volume-up, home, and power buttons - the device only turns off, and doesn't start booting again until I release all buttons and press the power button.
What are the exact instructions for entering CWM recovery on an S3, and do these differ for an encrypted device?
