If you have been a smartphone user for a while, you must have used a Nokia Symbian device. and if you have used a Symbian based phone, you must also be familiar with the good old tool for PC called NaviFirm. It was used to download the latest firmwares for the Nokia phones.
The easy availability of stock firmwares for any device might prove to be a lifesaver in specific situations. Google and Motorola offer a dedicated repository of stock firmwares for end-users. LG users can download the latest firmware using LG Flash Tool. It is very easy to find firmwares for Samsung devices via certain unofficial sites. Sony used to provide firmwares to Xperia users but it has now ended support for SUS (Sony update Service).
If you own a Sony Xperia phone or tablet and want to download the latest stock firmware for your device IaguCool from XDA developers has developed a amazing utility to make your day. His tool, XperiFirm is inspired by Nokia’s NaviFirm tool and can check the appropriate firmware for your Xperia device and download it for flashing manually using the Flashtool.
Please note that XperiFirm does not download the FTF file needed for flashing the device. It downloads the official file from Sony servers which can be decrypted and bundled to FTF using Flashtool. You can do this by launching the Flashtool and by clicking tools > Bundles > Fileset decrypt option.Then navigate to the folder with the downloaded firmware files and just follow the instructions to create your FTF. thus XperiFirm is far better than Sony’s PC companion because it lets you can choose the firmware of your choice without modifying build.prop on your device.
It’s really a terrific thing as you can now fix your phone that is caught into a bootloop, or unroots the device and restores it back to stock easily. The also lets you download the latest firmware for your device by disguising its baseband version or region/country. So, you do not need to wait till a software update reaches your country as you can get it as soon as it comes out from Sony.
XperiFirm is really highly useful utility for the users of Sony and Sony-Ericsson Xperia devices. You can easily download the latest firmware for Xperia devices with XperiFirm but before you can really do that, it requires a few things to be met on the part of the users:
Windows XP SP2 or greater installed on the computer
Microsoft .NET framework 2.0 or above
Sony Flashtool or Java Runtime environment installed on the PC.
