First of all, before installing you should have your galaxy S3 mini rooted. After rooting your phone you can install a custom recovery which can give you an interface to install a custom ROM to your phone. Install any custom recovery (TWRP recommended) but make sure it is latest custom recovery so that it can support Android 5.0 based custom ROMs.

You can sync all of your contacts to your Google Account. You can use Titanium Backup application available on Google Play Store to back up your important apps (this app requires root access). Backup all of your music files, pics and video files to ypur PC or any other external device.
In the tutorial below you will be told to make a backup of earlier ROM so that if you don’t like the Lollipop ROM or any thing goes wrong and you send your phone to boot loop then you can restore the previous ROM using this backup.
Now what you need to do this update are:
- A windows based PC (mac can’t do this), deactivate all antivirus or anti malware running on your PC as they can cause interference which can lead to a bricked device.
- On your phone enable USB debugging option (this is important).
- Make sure your device’s battery is at least 75% charged so it will not lose power during this process cause it also can lead to a soft bricked device.
- Remember that this tutorial is only for Samsung galaxy S3 mini only no other device can be updated using these files or this process as it can lead to bricked device.
