[Sony Xperia M4 Aqua] tutoiguaran:
Hi guys,

I need help with a problem. I have the cell since February, and recently is presenting a very strange behavior. when I'm going to make a call, changes from 3G to 4G and ndoen't allow me to make the call. while I'm browsing or using an app in 4g does not have any problem, but when it switch to 3g doesn't let me do anything.

I have already attempt recovery software with companion and not achieve anything. when I turn on the phone, it reaches the Sony logo and shutsdown.

the last thing you do was try flashtool and this was the log that shows:
