Cannot root my Xperia m4 (E2303) on Android 6.0.1 - Sony Xperia M4 Aqua

Hi,
A couple of days ago I tried to root my xperia m4 because I want to remove those annoying paid apps you can't remove without rooting. But I genuinely tried EVERYTHING! But nothing would work. The first problem I ran into was unlocking my bootloader, wich I could not do. I followed a lot of different guides but none of them worked. Below are a few links of the guides I followed:

I found a lot more "guides" but they were too sketchy if you ask me.
If someone is willing to help me, I would really appreciate it!

Go to the dialer and type in *#*#7378423#*#* until it pops ups the Service Info,then press Configuration and check for Rooting Status: Bootloader Unlocked,it should say Yes,if it says No then this is the reason any of the bootloader unlocking methods did not work and unfortunately you cannot unlock the bootloader.
And what error does it exactly say when you try unlocking? Make sure you have OEM unlocking and USB debugging on in the Developer Options.

It says my bootloader is not unlocked crying, to be sure I made a screenshot of the service menu.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I guess there's no way to unlock it, otherwise it would have worked I guess.

Theoretically you can use dirty cow exploit (stock kernel must be affected) to get temp root, after that you can get permanent root.

"Dirty cow exploit"? Never heard of that before, quite a funny name for an exploit if you ask me. I'll ask my good friend Google if he knows anything about this exploit. Thanks for letting me know!
And how exactly could I get a permanent root when I have a temp root? Can't find any information about it.

He can't unlock his bootloader

For a guide to unlock your bootloader using flashtool CLICK HERE.
Do that before attempting to root your phone as you wont be able to root as this is the first step and is compulsory

Yeah just looked at screenshot ,didn't look before "my bad"
Quick question in command prompt could he still flash a modified supersu boot.img for m4 with the locked bootloader (i've not had a device with unlock-able bootloader) is that possible ?

Unfortunately it's not possible. It's only possible to use some exploits

Good luck.

Since I'm not really experienced with this stuff, using an advanced exploit like the dirty cow exploit is probably not going to happen. But I am going to buy a new smartphone in the near future, this time I will buy one that can be rooted.
Thanks everyone for your help!
