brother yasuhamed,thanks for the help though may i ask something i have installed flashtool-0.9.23.1-windows.zip do i need to download the latest flashtool which is now flashtool-0.9.25.0-windows.exe or continue with flashtool-0.9.23.1-windows.zip.
as wanted to ask when do i flash this Night_Light mod is it after DRMFIX.zip, and finally Magsik17.x.
the flashtool has to be LATEST, older flashtools may not able to flash OREO in correct sequence
has certain files KNOWN as FCS script
when once xperia (xz) was on Locked bootloader, and was software repaired / upgraded via XPERIA COMPANION... what and HOW Xperia Companion did (in sequence) to your device (Flashed packets / bundles) in your XZ via USB cable while your device was connected in FLASHMODE... was CAPTURED by KEYLOGGER (software). This Key LOG was then Exported as JOB CARD as FSC Script and now FLASHTOOL READS that FSC script as instructions to mimic flashing as if XPERIA COMPANION was flashing your XZ...
hence its very important you keep your FLASHTOOL UPDATED
