This is the tutorial which explains how to unroot the Samsung Galaxy S3-I9300 smartphone to stock official firmware and restore the manufacturer warranty.

Obviously, rooting your Samsung Galaxy S3-I9300 smartphone give many benefits to you such as full admin access, remove the unwanted applications, add the necessary applications and allows the installation of many custom ROMs etc. But it will void your device warranty.

In case, if you want to get that back for any reason; then the only way is to unroot your Samsung Galaxy S3-I9300 smartphone. Full credits will go to the XDA senior developer, ashwin123 who have come up with this tutorial.

So, the Samsung Galaxy S3 users who wants to unroot their device safely can follow the given below tutorial. But before go to the actual procedure I suggest you to follow the given below pre-requisites without fail, otherwise you may face any issues while implementing the procedure on your android phone. So, let’s start:

Pre requirements:

• First of all I would like to suggest you to take a full backup of your android phone. Probably you did the same while you root your device.

• Backup everything on your phone which includes SMS, MMS, Contacts, Applications, Videos, Files etc. If you have CWM/TWRP recovery then take a backup of that too.

• Next you are advised to install the USB drivers specifically available for Samsung Galaxy S3 smartphone. So, then you can transfer the files between your computer and the android device.

• Then enable the USB debugging mode on your device to connect it with the computer and use the android SDK with it. (To reach the USB debugging mode press menu > settings > applications > development option).

• Make sure your Samsung Galaxy S3 phone is unlocked.

• Then check the battery percentage level of your phone and if it is less than 75% then put full charge.

• Then make sure your phone was rooted with the help of “Root Checker” app.

• After that check the binary counter/flash counter your device and reset back it to zero by installing TriangleAway v2.9.0.apk released by the XDA developer-Chainfire.

What is flashcounter? Samsung created the flashcounter into their devices to track down how many times a user changed the stock ROM into the custom ROMs. Whenever you’re flashing a custom ROM, the flashcounter goes up and your device warranty gets void.

• The stock firmware which I have given below is compatible only for the Samsung Galaxy S3 I9300 device. So, don’t use that for other variants of the same manufacturer. If you do so; without any doubt it will brick your device. So, before start just verify your phone model number by going to the path “Settings > About Device > Model Number” and install the relevant firmware according to the country or region.
