This experimental software allows you to flash firmwares acquired through XperiFirm to Sony phones including and newer than the XZ Premium.

• Place the newflasher executable into the firmware folder (usually created by XperiFirm)
• Run Newflasher. Everything inside the folder will be flashed, so remember to remove files you don't want on your device beforehand.
• To take a trim area backup without flashing anything, run newflasher Dump-trim-area. It writes the same restorable tadump/tadump_1.ta and tadump_2.ta as the flashing run does and then exits.

Install gcc, make and development versions of zlib and expat. On Debian-based systems such as Mint and Ubuntu, this means:

sudo apt-get install gcc libexpat-dev libz-dev make

On Darwin you need to install libusb-1.0, this means:

brew install libusb

Download, build and install, assuming that ~/bin is in $PATH:

git clone https://github.com/munjeni/newflasher.git ~/.local/share/newflasher
make -C ~/.local/share/newflasher
ln -s ~/.local/share/newflasher/newflasher ~/bin

make newflasher.[exe/x64/i386/arm32/arm64/arm64_pie], exe referring to a Windows build, the rest being for Linux Android and Darwin.
