Sdk tools
On developers site its written that you need android sdk tools but you have only mentioned fastboot package with drivers..
So it is necessary to install sdk tools or only this rar file?
Thanks

Rar file is enough

Wether the device's bootloader is unlocked or not?
I tried unlocking the bootloader of my device: Sony Xperia M (C-1904) using cmd technique. It got finished successfully. But after i unplugged the phone from the pc and turned it on, it got stuck at bootloop. To solve this I tried to reflash the whole firmware (which i downloaded from Xperifirm) and i got success. My phone started working again. After that I rooted my phone again which was also successful. But now i don't know wether my device's bootloader is locked or unlocked. Can anyone tell me the easy way to check it??

Phone > *#*#7378423#*#* > Service info > Customisation. Rooting status will say "Bootloader Unlocked: yes". Re-flashing firmwares doesn't relock the bootloader.

As per you said, i tried that method and i got the result as:
"Rooting Status:
Bootloader Unlock: Yes"
So does it mean that my bootloader is unlocked.

Providing that it says "Bootloader Unlocked: yes", and not "Bootloader Unlock Allowed: yes", then yes it is unlocked.

[q] i cant unlock the bootloader anymore

I try to unlock the bootloader of my xperia m using flashtool and after i unlock, my device stuck in bootloop and flash it again to reunlock but still in bootloop,after that i flash the stock firmware and my device back to normal, and now im trying to unlockbootloader again but it failed. . .it says FAILED remote command did not succeed. . .any help please. . . .

It failed because the bootloader is already unlocked. You can verify this by going to phone>typing *#*#7378423#*#*>service info>configuration>rooting status. Under the rooting status you will find the bootloader unlock status, yours will say Bootloader Unlocked: Yes.

my devices is locked,i checked it rooting status: Bootloader unlock allowed: Yes. . .and when i connect my device in emma app it says locked. . . .

Try requesting a fresh key from Sony and using the new one.

Sony Xperia M 4.3 Locked Bootloader CynogenMod

Device: Sony Xperia M C1905
Software: 4.3
Bootloader: Locked
Basically, every single method I have tried to root this phone has failed. All I want to do is have root access to my phone, I want to be able to:
Use CynogenMod (FOR CLASH OF CLANS)
take my apps2SD
Delete any crap from my phone
Full Customization abilities
All this can be achieve by rooting but MY BOOTLOADER IS LOCKED.
There are numerous ways out there that just don't work.
Does anybody know how to first root my phone, and then to have access to a mod?
I want the mod to be able to do all the things I listed previously.
I know this is possible with CynogenMod on other phones, but my bootloader is locked, and I just don't know what to do. Done numerous tutorials, none seem to be working or some don't even have any download links.
If someone could give me a step by step guide on how to mod and root my phone that would be perfect.
I will respond very quick, and will ask you questions if I need help.
I will listen and try to follow your steps, but please give me specific details, I'm not a pro modder.

Simply use towel root and get full root access
Just search in threads, how it works

I have tried that. I followed each step with the towel root hack.
Basically, after I've done it I go on Root Checker and no the root is not successful.
And with towel root you can't use Cyanogenmod.

You can't use Cyanogenmod if your bootloader is LOCKED, I have the same problem, my bootloader is on "Bootloader unlock allowed: NO" status, you can't because Cyanogenmod uses a custom KERNEL, which is impossible to do if your bootloader is locked. All we have to do is to wait for somebody to make a LB (locked bootloader) version of Cyanogenmod.
