The major Japanese smartphone manufacturer Sony has been rolling out the latest Android 7.0 Nougat firmware update (32.3.A.0.372) to the Xperia X and the Z series phones. The Xperia X, XA, X Compact, XZ series are already running the Nougat firmware. Moreover, the Xperia X family has now received the January 2017 security patch level with new build number 34.2.A.0.292 over the previous number 34.2.A.0.273. Usually, your device would receive the software update over-the-air (OTA). However, for the users who have rooted their Android or setup a TWRP recovery, the OTA won’t be of much use. Hence, you will need the full stock firmware and use it to restore Sony Xperia device to complete stock.
The Xperia Z or X series stock firmware files come in FTF format. This is a special format designed exclusively for the Sony smartphones. You can download it using the XperiFirm to get the direct download link from the Sony servers or you can simply connect your Sony Xperia device via Sony PC Companion and flash the latest updates. However, using the companion, you won’t be able to get the firmware files for yourself. This is where the XperiFirm comes in. Download the latest XperiFirm v5.0.0 and see how to use it.
