Once you unlock the bootloader, root and install a custom recovery on the Samsung Mesmerize smartphone, you can start installing some of the best custom ROMs for the device and change the way it looks, feels and operates. Custom ROMs are also great on the Mesmerize device for adding new features and removing the stock apps which might be bloating your device — something that often happens on Samsung devices.

Files You Need

You will need to unlock the bootloader and root the Samsung Mesmerize smartphone before you can install custom ROMs on the device. With Samsung devices, many times the rooting — especially if you are using Chainfire’s CF-Auto-Root tool — there is no need to unlock the bootloader because the rooting exploit will unlock it for you.

You must install a custom recovery on the Samsung Mesmerize before you can start uploading your custom ROM files.
