What does the difficulty rating mean?

At xda-developers we post a variety of software tweaks that can help improve the function of your device. Not all tweaks are created equal, and some are more difficult to employ than others. This difficulty rating system provides an easy way for you to determine the required skill level for a given tweak. It’s defined as follows:

3 stars: Expert skill required. Potential damage to your device could occur if tweak is done improperly.

2 stars: Intermediate skill required. Little or no damage will occur to your device if tweak is done improperly.

1 star: Beginner skill required. Anyone can attempt.
