Download Stock Firmware
The first step is to download the stock firmware for your Sony Xperia A4 SO-04G from Xperifirm. Xperifirm is a tool that lets you download the latest firmware for any Sony Xperia device from the official servers. To use Xperifirm, you will need to have Java installed on your computer.

Wait for the download to complete and close Xperifirm.
You should now have a folder named after your device model and firmware version, containing several files with .sin extension.
