so I tried to update my software using flashtool. after flashed sucessfully, I turned my phone on but it said the software update was failed. so I tried to fix it by using the same application on my computer. "the software update was failed" notif is gone but now I face new problem that my phone is stuck on xperia logo when I try to turn it on. I was trying to fix it by software repair of sony companion application but it said the sony software repair error. I've been trying to follow the instructions well but I can't make it. what should I do?
fyi, my phone is Xperia XZ F8331, the back phone is written DoCoMo SO-01J.
