In order to use ROM Manager, you must be rooted.
What is ClockworkMod Recovery?
ClockworkMod... also known as Clockwork and CWM – is a custom recovery for Android phones and tablets that allows you to perform several advanced recovery, restoration, installation and maintenance operations on your Android device that aren’t possible with the stock recovery. In what follows, we will cover all that this recovery is capable of doing, and how to do it.
ClockworkMod recovery is one of the most widely used custom Android recoveries that is available for most mainstream Android devices. ClockworkMod recovery has been developed by Koushik Dutta (also known as Koush) – the same guy who brought us the Android ROM Manager.
Go to the Market and Download ROM Manager > -Once installed, open ROM Manager
Flash ClockworkMod Recovery: This only needs to be done once when first installing the app or whenever an update is available.
Next reboot your phone.
Create a Nandroid and backup your current ROM:
What is a Nandroid Backup? Nandroid is a set of tools that will enable anyone who has root on their Android device to make FULL system backups, in case something goes wrong or you want to try out that new experimental ROM/theme. It will return your phone back to the condition it was in when you made the backup.
There are two ways of doing this:
From ClockworkMod Recovery OR From ROM Managers "Backup Current ROM" option.
What's the difference? None really, both ways will create a nandroid backup. It's always good to manually learn what goes on in recovery and not rely on an app to do everything for you. One plus of using the "Backup Current ROM" option is, you get to rename the backup file right away if you like to (there's no need to use a file manager app to find the backup and rename it). One negative is if you ever use the "Manage and Restore Backups" option and you need to restore a backup, there's no option for wiping the caches (supposedly you don't need to when restoring a backup but it's better to be safe then sorry and not have to worry about something going wrong). Another reason would be if you are ever not able to get into ROM Manager and you physically have to boot the phone into recovery. So, for that reason + others that I will mention later in the Installing ROMs section... This tutorial will show you manually how to do things in recovery.
Note: use volume up and down buttons to scroll up and down the menu list and the power button to make selections.
*The backup may take up to 10-15 minutes*
Now that you have installed CWM Recovery and performed a full system backup, you are ready to install/flash Android themes, kernels, tweaks and custom ROMs.
