Smile [Help] How to backup & restore EFS of SHV-E330S?

I'm planning to downgrade my Galaxy S4 SHV-E330S from 4.4.2 to 4.2.2 hoping that my battery life will be fixed (only 3hrs of screen time). I was told that I have to backup my EFS so that if anything goes bad e.g. Losing my IMEI, i can recover them. Please teach me how to backup and restore it surely and safely. Thank you very much!

You cant downgrade. Anyway you will have battery drains, random reboots, Warranty Void, no wifi, no bluetooth, etc if u are succefull.
