A new Android Lollipop 5.1.1 based custom ROM, named Dirty Unicorn has been released for the Samsung Galaxy S3 3G, the 2012 flagship device of this reputed company. Reports suggest that it is a stable firmware with no bugs or glitches and comes at a size of 197MB.
The ROM is also further optimized to increase performance as well as extend the battery life of the Samsung Galaxy S3. Before installing it, keep in mind that the Dirty Unicorn custom ROM should only be installed on the Samsung Galaxy S3 GT-I9300 which comes with an Exynos chipset. If you try this on other devices, it could get bricked.
You can check the model number of your device by heading over to Settings >> About Phone >> Model Number. Before you proceed, make sure that your device is rooted. You should back up all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone as the process as the installation process clears memory and you might not wish to lose valuable data through the process.
USB drivers for your device should be installed on your PC or your device won’t get detected. Before proceeding with the installation, make sure that your device has at least 80% of charge. You don’t want your device to get bricked in the middle of the installation due to no battery.
Installing this custom ROM might enhance your user experience with the device but it will void the warranty. As a result, you need to install the stock ROM again in order to restore warranty.
This procedure is quite a technical one and should be done by professionals or people knowledgeable about it. In case your device is bricked or damaged in the process, Day Herald should not be held liable.
