Thank you, what tool would you recommend? I only found the flash tool off the Sony dev site. I will need one for sure, returned the US variant and ordered the global one. Should be here in a few daysHey Hurt,
Usually with the Xperia phones, or at least with the 1 series, you do not need to unlock the bootloader to flash. It is just a matter of using a flashing tool, run a executable, and it does it's thing. Only thing for unlocking the bootloader is to root.
I spent time flashing roms for phones of all kinds, and yes, unlocking the bootloader was always part of the process. And cross flashing region, even hardware different phones is allowed (which is weird because it's a no no for other company phone models, which can lead to bricking). I flashed my Xperia 1 II from US to SEA firmware. And also crossflashed my CT72 HK to SEA with no issues.
So try to cross flash the firmware to an Asian firmware if you can or still willing.
XDA for Xperia 1 III guides helped me flash.
