Cyanogenmod 14.1 ROM for Samsung Galaxy S3 I9300
Cyanogenmod 14.1

Samsung Galaxy S3 i9300 was a legendary device that was a complete package during those days. The device has the hardware that can run all the current Android versions without any problem. But the problem lies with the company. After a time period, manufacturers start focusing on new device & stop pushing any updates for their old device. This is very common with companies who release many devices in single year. We can’t blame them as the device is quite old & it won’t be having much users. But thanks to custom ROMs, you can still enjoy the Galaxy S3 with Android Nougat (7.1).

The ROM is completely Official but is quite painful to install. Once you’re done with installation, you’ll experience the smoothest ROM for Galaxy S3.

You are STRONGLY recommended to fully wipe your device before flashing, and if possible avoid restoring system apps and system data with Titanium Backup – these can cause stability issues that are very hard to debug. If you believe you know what you’re doing – then fine, go ahead, but please don’t complain if you experience strange behavior.
