This guide will instruct on how to create a nandroid using cwm
a couple of things first:
1. Nandroid simply backs up system and data. it does NOT back up your kernel or modem.
2. For the reasons in note 1, you can only recover to a nandroid on the same build as the one you are on (EC07 - ECO7, EC03 - EC03, and DL17 - DL17). If you try to back up to an EC03 nandroid from an EC07 build, you will softbrick until you flash the proper kernel.
Also, this guide assumes that you are already rooted, and have CWM working on your phone. If not, there are a couple of guides to get you here.
What you need:
Nothing that you don't already have.
What to do:
1. reboot int recovery by powering down, then power back on holding vol up, vol down, and power at the same time. This will boot you into stock recovery.
2. using volume down, highlight 'apply sdcard:update.zip' and select by using the menu button (or where it would be).
3. you should now be in cwm recovery. Depending on which one you are using, the text will either be red or cyan in color. highlight 'backup/restore' using volume keys and select with POWER button.
4. select backup
The back up will start, and will take around 5-10 minutes to complete (depending on how much stuff you have in /data)
5. Once it is done, it will go back to the main cwm menu. Select 'reboot phone now' with power button.
you are done.
This is pretty simple and innocuous. But, as always, ask before you start.
