So I have an xperia M4 Aqua Dual (E2363), it is not rooted, locked bootloader, usb degugging disabled, basically straight from the factory.

When I turn it on all I get is the white Xperia screen, it doesn't loop, but it doesn't get any further.
I can get in to fastboot mode but I don't think I can do anything here since usb debugging is disabled right?
If I try flash mode, I get the green light but the phone is never detected in flashtool (tried windows and linux versions 9.23 and 9.18).

Some background:
I have been having problems alot recently, so much so that in the past 3 weeks I have used Xperia Companion to software repair 5 times. I have also had problems since I got the phone, but not as frequent as recently.
Usually XC software repair works, but just like with flash mode in flashtool, XC no longer detects when I plug the phone in.
Based on that I have always had this problem, albeit not as often, I think there must be some hardware problem.

Is there anything left that I can try?

Well, first of all, this is not an Xperia M4 section. This is Xperia M(2013) section. So from next time make sure you post in right section because Xperia M4 users will be able to help you better.
Now coming to your problem, device might not be getting detected because you might not have installed right drivers for it.
In flashtool installation directory, you'll find fastboot drivers. install drivers for your device.
Another problem might be from your pc. I remember my laptop is giving me error "USB not recognized" but my pc works well. So just try it.
Hope it helps
And from next time make sure you post in right section.
