 Installing Android 5.1.1 Lollipop On A Galaxy S3 Mini

While Google may be installing Android 5.1 Lollipop in their new and their past flagships, Samsung seem to be just too lazy to follow suit. It looks like the Galaxy S3 Mini is going to be left stuck with Android 4.1.2 Jelly Bean.

For disappointed Mini S3 users, a custom ROM might be the only way to get a higher version of Android in their device. New Maclaw studios has come up with just such a ROM.  They have a ROM based on CyanogenMod 12.1 which can install Android 5.1.1 Lollipop on a Mini S3.

In this guide, we are going to show you how to install the Android 5.1.1 Lollipop CyanogenMod 12.1 stable custom ROM on the Galaxy S3 Mini I8190, I8190N, & I8190L. 

Preparing your phone:

  1. Before you install this ROM you need to make sure that it’s the right one for your device. Installing a ROM that is not compatible to your device can result in bricking
    • Go to Settigs -> About Divice. You should see your device’s model number fromk there.
    • If your device is NOT a Samsung Galaxy S3 Mini GT-I8190/N/L, DO NOT install this ROM.
  2. Make sure you have enough battery life. If your device loses charge before the flashing finishes, you could brick your device.
    • Charge your phone to at least over 60 percent
  3. Make sure you have installed custom recovery on your device.
  4. Back up your contacts list, call logs, messages and your important media content.
  5. If your device is already rooted, use Titanium Backup for any important apps and system data.
  6. If you’re already using a custom recovery, back up your current system using Nandroid Backup.
  7. The reason you need to back up the mentioned data in Steps 4-6 is because you’re going to need to go through Data Wipes during ROM installation.
  8. Before you flash the ROM, make and EFS backup.

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.
