Install Galaxy S3 Mini I8190 with CyanogenMod 10 Jelly Bean 4.1.2 Custom ROM

Samsung Galaxy S3 Mini I8190 is this close to having its very own Android 4.1.2 Jelly Bean operating system. Something we should be thankful for thanks to a little tool called CM10 custom ROM. The latter will also come with some not so nice things; so you should expect bugs, issues with USB mounting (OMX codecs and RIL, too), FC errors and so on.

Our advice to you, if you encounter such problems, is to try a different custom ROM which offers better stability; or you can also try to install the default ROM again. But, if you don’t run into any of the above, then just prepare yourself to be shown how to get the Android 4.1.2 on your Galaxy S3 Mini I8190 with this tutorial.


For now, though, you need to consider various pre-requisites: root the smartphone using this tutorial (and gran either CWM Recovery or TWRP on it), turn on USB debugging, install USB Drivers for it on the laptop you work with, charge the battery of the handset, backup all of the data you see as crucial and then see if your device is factory unlocked.

After you get all of the above in order, you will have to consider something else. Which is represented by a group of steps as shown below. Follow all of them and your smartphone will have its Android 4.1.2 Jelly Bean at long last.Galaxy-S3-Mini-I8190
