Important instructions

For step one we prepared the following instructions: download Odin tool v1.85 together with , and on the laptop you have in front of you. The files that are in the first archive need to be downloaded on your laptop, too, then you need to turn the handset off.
Step two is wanting you to do the following: press + hold Home and Volume Down at the same time, press Power and stop doing that when the Android logo is spotted on the phone’s display; confirm the fact that you want to see the Mini enter Download Mode by pressing Power.
Step three is finally here and it needs you to launch Odin tool on your comp. Then plug the handset to the latter device. Be sure to wait for both of these devices to connect to one another successfully; that will happen when you see an ID:COM icon in yellow and a number (the COM port) on the touchscreen of the Galaxy S3 Mini. Your work now should include choosing four files as shown below:
– one which has CODE in its name and which you can see if you click on PDA;
– one that contains MODEM in its name; gain access to this file by clicking on Phone;
– a file with CSC in the name it comes with; see it pop on the screen after you click on CSC;
– the file called .pit (you shall see it after you click on PIT).
Tip: don’t do any of the above if no such file comes on the phone’s display.
[sc name=”banner-jos”]For now you should do as step four tells you to: activate F. Reset Time and Auto Reboot while you are in Odin, then check Re-partition, too, should you have seen and opted for the .pit file.
In Odin, click on Start and wait for the installation of the firmware to end, then have some patience, once more, till the GT-I8190L restarts.
The home screen will appear soon. When it does, you will need to disconnect the phone from the laptop.
