Install Android Lollipop On Galaxy S4 Mini I9192 Using CyanogenMod 12 Custom ROM

The dual SIM variant of the Galaxy S4 Mini, the I9192 turned out to be a very lucky device as it received the unofficial Lollipop treatment by XDA senior member k2wl, who has been pretty much active on the Galaxy S4 Mini development since quite a long time. CyanogenMod has already provided the source code for CM 12 and the developers are coming up with Android 5.0 Lollipop packed inside this unofficial CyanogenMod 12 for various devices. Although this ROM for Galaxy S4 Mini Duos is in very early development stages, but at the present time, the very basic functions are found to be working and make this ROM a good choice for those who cannot cage themselves with the existing Android 4.4.2 KitKat firmware of the Galaxy S4 Mini Duos.

We will be installing this unofficial CyanogenMod 12.0 custom ROM on our beloved Galaxy S4 Mini Duos GT-I9192 in order to update it to Android 5.0 Lollipop. Before we proceed, it may be kept in mind that this is a custom firmware and there’s always a chance for bugs in these firmwares. This firmware may not be kept for everyday use on your Android device, you may only proceed if you’re a custom ROM freak and you can handle mishaps that usually occur while flashing these custom operating systems. Newbies are recommended not to flash this ROM.


Early Preparations

1. This Guide Is Only For Galaxy S4 Mini Duos GT-I9192

This custom ROM is only for the device mentioned above. Make sure that your model number matches the one listed above. To do so, go to Settings > About Device on your device and see your model number. Flashing this ROM on any other device will result in bricking it so make sure that you meet this requirement first of all.

2. Battery should be charged at least over 60%

Make sure that your battery is charged enough to complete the flashing process. In case your battery is low and your device goes dead during the flashing process, you may end up soft bricking your device as it won’t complete the flashing process.

3. Flash a Custom Recovery

A custom recovery is required for flashing this ROM. You may use our guide to from here to install Philz Advanced Touch CWM recovery on your Galaxy S4 Mini I9192.

4. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.

  1. Backup SMS Messages
  2. Backup Call Logs
  3. Backup Contacts
  4. Backup Media – Copy your files manually to your PC or Laptop.
  5. Backup EFS
  6. Titanium Backup – If already rooted, use Titanium Backup to backup all of your apps, system data and other important content.
  7. Backup Nandroid – You can do this using CWM/TWRP recovery.

5. Disclaimer

The methods involved in flashing custom recoveries, ROMs and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is SAMSUNG in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. In case of any mishap we may not be held responsible. If your device has the Knox counter on the bootloader, it will be tripped and you won’t be able to reset it ever. Follow these instructions to the letter to avoid any mishap or bricking. Make sure that whatever you do, you are doing it at your own responsibility.
