These are the instructions to root Samsung Galaxy Grand Max smartphones running on Android 5.1.1 Lollipop using the updated CF-Auto-Root tool, a Windows computer and the Odin flash tool made by Samsung developers.
- You must follow this guide if you have the Samsung Galaxy Grand Max with the SM-G7202 model number only.
- The rooting exploit in this guide is based off the Android 5.1.1 Lollipop and LMY48B.G7202DDU1BOK1 firmware. You do not need to be on that same firmware to use this guide. It is just an indicator for you to use. Some of the older Samsung devices refuse to boot older images.

The Samsung Galaxy Grand Max is now rooted and you can immediately head over to the Google Play Store and start installing any apps that require that same root access to run. The CF-Auto-Root tool installed and enabled SuperSU on your device — you can see it now as an application available from your app drawer. That same SuperSU is going to grant the rooting permissions to any app that requests the same. In addition to granting access to apps, it is going to block any apps that could be malware. Only apps you grant access to the internal system can get through.
