"**is rooting safe**"  
The answer is difficult. Every tool you use to root your device says **do with your own risk and we are not responsible for any damages caused to your device**.

**is root legal**  
Nothing to do with legal but it voids your devices **warranty**.


**does my device becomes slower**  
No , many tools and tweaks are available to speed up rooted devices .

**what is the best rooting tool**  
That depends on what device you use.

**about data loss**  
No data will be lost. However a backup is taken to avoid data loss.

Try googling to find the best rooting tool for your particular device. Alternatively, 
you can download some rooted stock roms (specific for your device) and flash them using recovery.

Try e.g. **Kingo root**, this is the best for me.
