Backup your all important data and apps because during any installation of a new custom ROM or Official Firmware , your device will be wiped and cleaned with new operating system. Make a backup for just in case, you never know when anything might go wrong.

Samsung user can also backup data by using Official Sumsang Kies. If you backup data manually, you will get more options for what to choose from. You can also move your data to other Android devices from different manufacturers, i.e moving Samsung Galaxy S5 backup data to Google Nexus 10. If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.

Few more important things that you must remember before installing any custom ROMs or Official Firmwares:

• You might face some problems in connecting your Android device to the computer. How to fix? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and KitKat.

•  Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage.  Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

• Most of the tutorials and how-to guides on iDroid Horizon are for factory unlocked Android devices. We recommend NOT to try our guides if your device is locked to a carrier, unless we have specified the device model or carrier name.
