Rooting, flashing, backing up data; these are just some of the terms long-time Android users are very familiar with. Newbies would probably scratch their heads and look up the ceiling, trying to understand what these are for and how to do them.
Even users with sufficient knowledge about tweaking Android devices would sometimes avoid flashing or rooting because of the fear of voiding their warranty or worse, bricking their device. But, just recently, an all-in-one toolkit was developed by an XDA Developers member which answered the needs of both new and not-so-new Android users.
The Samsung GS3 ToolKit v2.0, developed by XDA Developers member mskip, packs almost all of the functions an Android user needs to pretty up his phone. Aside from the staple rooting and flashing, the toolkit can do a lot more. If this strikes your fancy, follow the instructions on how to acquire and use the toolkit.
