The Samsung Galaxy S4 Mini now has a new software update available that users can install manually with the Odin flashing tool. The new build number is L520VPUBOH1 and it upgrades your OS to Android 4.4.2 KitKat. The most important part about this update is that it comes with the StageFright security update.

REQUIREMENTS

• You can only apply this software update on the Samsung Galaxy S4 Mini device. The reason for that is because the firmware is made for this device only and if you were to flash it on a different device, you would probably brick down that device.
• Those people who did accidentally apply this update on the wrong model number will need to search a Samsung firmware website like Sam Mobile and find the correct firmware for your model number. Now flash that correct firmware file on your device and the problem should be fixed. It was only a soft brick situation, but still a bricked device nonetheless.

BEFORE WE BEGIN

• Download the Samsung USB Drivers for mobile phones. You can get them from the official Samsung website download page. We already have that shortcut link for you available from our USB drivers page here. Just scroll down the page until you see the Samsung name.
• You must have a Windows PC to install this update. You cannot use the Odin flashing tool on Mac OS X or Linux. The guide works for all Windows operating systems apart from Windows RT on a Microsoft Surface tablet. The Windows RT environment is a unique environment that only lets users install apps from the Windows App Store. That means it won’t accept the Odin file you have below unless you jailbreak it.
