How to debrand my Samsung Galaxy S3 and remove carrier branding? This is the question that many new Galaxy S3 owners make when they buy the phone from a carrier on a contract.
Most of sold devices are unlocked and not branded. They aren’t locked to a specific carrier and can be used worldwide because they aren’t on a contract.
But those Galaxy S3 devices that are locked to a carrier, are branded with the carrier logo and sounds.
When you reboot your branded Galaxy S3, during the boot animation, the carrier logo will show up. The same thing happens during the shut down animation.
Not only that, but a branded Galaxy S3 is full of carrier bloatware. There are a lot of pre-installed applications that a normal user cannot uninstall.
If you are tired of your bloated and branded Galaxy S3, follow the guide below to learn how to install stock unbranded firmware.

Your Samsung Galaxy S3 should have at least 60% of battery left in case the phone freezes and doesn’t die in the middle of the process. Make sure to follow the guide carefully and nothing bad will happen to your phone.
If you don’t carefully follow the instructions, you can break your phone and turn it into a hard bricked device.
