How To Fix Android Bootloop Problem On Sony Xperia Mini (ST15I)

First, you need to download the latest Sony PC Companion Software onto your computer. You can get and download the latest PC Companion here.
The main gist of this procedure is that you will be able to restore your smartphone and get rid off that Android bootloop problem. You will be able to use your Android smartphone afterwards but the only catch (not really a drawback for me) is that you will lose all of your stored data and information except for those that are saved in your SD card. Another thing that you have to consider before taking the plunge is that with this procedure, your Android smartphone will have to accept and use the latest firmware.

The author from the source also said that it will be much appropriate if you restore or install the stock ROM from the PC Companion tool.

1. Go to the “Support Zone” on your PC Companion;
2. Click “Start”, but don’t connect your smartphone yet;
3. An overlay pop-up window will open, click the “Repair phone” link from there;
4. Click on “Continue”;
Somewhere along the succeeding steps from your screen, you will be asked to choose your handset. Then that’s the only time where you will be asked to connect your smartphone into your computer then you will be asked to press the “Back” button.
5. A notification overlay window will pop-up  to notify the user that ALL data will be lost and you need to confirm this by ticking the check box and click on “Next”;
6. You’re almost close to the finish line. This is the last step but the most crucial one because you need to have a very stable Internet connection and as much as possible it should be fast enough. The last stage of this whole procedure is that with your PC Companion, it will download the latest firmware or stock ROM from the server and install it on your handset. This might take a while depending on the speed of your Internet. So you’d better be patient.

VIOLA! That’s it. You may now remove your Sony Xperia Mini (ST15I) from your computer and customize it again.
