Before you start installing custom ROMs or MODs, you might want to make a backup ROM.
What is a backup ROM?
Backup ROM consists of your whole OS, settings, apps, app data, and pretty much everything except for contents of your internal storage such as personal photos, videos, and other files.
Why backup ROM?
Having a backup ROM is very useful when you end up in a bootloop or you don’t like the new custom ROM you’ve installed. By using the restore feature, you can easily be up and running on your old ROM within minutes.
I highly suggest you to make at least one backup ROM after rooting your Nexus 5, so you always have a restore point.
You can also use backup ROMs to try multiple custom ROMs, save them as backup ROMs then restore them when you want to switch ROM.
Before we begin, you must have a rooted Nexus 5 with CWM or TWRP recovery installed. If you do not, please follow our Nexus 5 Root Guide first.
Step 1. Turn off your Nexus 5. Then hold down Volume Down and Power buttons together for about 2 seconds until you see bootloader menu.
Step 2. Choose “Recovery mode” using Volume buttons then hit the Power button to enter recovery.
Step 3. Once in CWM or TWRP recovery, choose the “backup” menu and backup ROM, very easy to do.
For TWRP, you will be able to also set your backup name.
Once done backing up, your backups are stored in your internal storage under TWRP folder for TWRP Recovery and under ClockworkMod folder for CWM Recovery. You can always copy the whole folder to your computer to save space and copy it back to your Nexus 5 when you need to use it for restoring ROM.
Step 4. To restore ROM on your rooted Nexus 5, simply boot into recovery like you did in Steps 1 thru 2, then hit “Restore” menu and choose the ROM you want to restore.
Step 5. Once done restoring ROM, simply reboot and you should be on the ROM you backed up!
