Before we get along with the upgrade process, let us outline the necessary requirements and important tips again. This upgrade applies to the international variant of Galaxy S III (GT-I9300) only, you can verify your phone’s model in Settings > About Phone > Model Number. Here are some of the update prerequisites.
1. Prerequisites
- CyanogenMod 11 M8 “cm-11-20140708-SNAPSHOT-M8-i9300.zip” update package
- Custom Recovery (CWM or TWRP) and root access on your phone
- A USB cable with latest Samsung USB drivers installed on PC
- At least 70% battery left on your phone
- A complete backup of contacts, app data, messages, and other important data stored in phone memory.
Note: This process involves flashing a new custom ROM which will completely wipe-out your phone’s internal memory. That’s why you’re recommended to store an image of your current system first, either using your custom recovery or through Titanium Backup/Samsung KIES utility.
Disclaimer: Although, this CyanogenMod 11 build is almost bug-free and has been fully tested on GS3, we still can’t guarantee whether it’ll cause any system malfunctions or not. I shall not be held responsible if you get your device bricked (which is very unlikely) at any point during the upgrade process, so proceed at your own risk – Â you can come back later when you’ve gathered enough courage.
