One of the first things you will want to do after you root your Atrix 4G is to make a backup copy of your rooted ROM.
If you are going to install new ROMs or overclocking kernels, you will want to make sure you have a restore point, sorta like Windows 7 system restoration feature. This can be done easily using ClockworkMod Recovery, which allows you to completely backup/restore your current ROM, whatever it’s on.
This backup method will backup all your settings, contacts, apps, ROM, and the kernel. It won’t back up contents of your internal storage of SD card. For that, we suggest you to simply copy over the contents to your hard disk.
Once you get those out of the way, simply get into ClockworkMod Recovery by rebooting while holding down both Power button and Volume Down button until you see “fastboot” on the screen.
Simply hit the Volume Down button until you see “Android Recovery” then hit the Volume Up button.
Once ClockworkMod Recovery menus show up, choose “Backup and Restore”.
Here, you can choose “Internal SD Card” or “External SD Card”. If you have a microSD card inserted into your Atrix 4G, you can back up your ROM in it or on Internal storage.
You can either choose “Backup” or “Restore” to backup your current ROM or restore your backed-up ROMs.
Once backup starts, it should take about 5 minutes. When it’s done, you are good to go, reboot your phone or install new ROMs and enjoy.
