The Galaxy S3 Mini GT-I8190 was released back in October 2012 as an economy phone with high-end features.It is a stripped down version of Samsung’s best-seller the Galaxy S3. The S3 Mini features 4.0-inch WVGA (480×800) capacitive touchscreen display, 1 GHz dual-core processor,  5 MP Auto Focus rear camera, 1GB RAM, and a 1,500 mAh battery. The device was released with Android 4.1.1 Jelly Bean firmware out of the box and was later treated with Android 4.1.2.

Despite of its popularity, quite surprisingly the Galaxy S3 Mini has failed to attract due attention from our developers. As a result, even after months of its release, the device has not got the official CF-Root. If you happen to be an owner of this mini powerhouse and want to root it, here is an easy guide that will help you in achieving this goal. Usually, when we write a rooting tutorial, we post links to a rooting package and flashing it to  a phone would root it. But here the procedure we are going to describe involves installing the complete official firmware with a twist. The firmware posted below is pre-rooted, that means it has SuperUser app injected inside.

Rooting your phone using this method has one great advantage- it does not give you a yellow triangle. The flash counter is not increased and thus you phone’s warranty remains intact.

Update:

Now we have a full-fledged tutorial for rooting all 3 variants of the Galaxy S3 Mini. Please check this post.
