There are many official ways how to update firmware on your Sony XPERIA smartphone. You can use PC Companion on Windows computers or you can use Sony Bridge for Mac on Apple computers. But sometimes it is better to use unofficial way - you can get latest firmware for your phone immediatelly without waiting. Download NewFlasher for new XPERIA smartphones like XPERIA XZ1, XPERIA XZ1 Compact or XPERIA XZ Premium.

Long time the only unofficial application for flashing XPERIA smartphons was Flashtool. But after Sony Mobile release smartphones with Qualcomm Snapdragon 835 (XPERIA XZ1, XPERIA XZ1 Compact or XPERIA XZ Premium), Flashtool doesnt work with this phon. But thanks to munjeni from XDA we get new tool for flashing XPERIA devices. It is very simple and easy to use tool. There is not such attractive UI like Flashtool, but it worked perfect. Thanks to this tool you can update your smartphone to latest firmware version, unbrick your smartphone or make debrand, when you buy phone from carrier. You can download NewFlasher 10 for Windows from here. Like my website? You can download my XPERIA Beer theme for free here or you can donate.

Why should I use NewFlasher?
- once bootloader unlocked, official sony tools do not work anymore
- using official sony tools, you can only upgrade. No downgrade possible 
- using NewFlasher, you can choose what to flash and what not to flash
