if so, don't force to unlock your phone, because it will end up hard brick!

If it says no, it's no. Nobody but Sony can change that. Fact.

[Q] Unlock Bootloader even if it's now allowed

My name is Dante, and i have the xperia M2 d2305, and it says Unlock Bootloader allowed: NO ,
And i have read that i change it by free or anything, my questions are :
1) What happens if i try it anyways ? does anyone know ? will it brick or bootloop or will it work ? i dont want to and i would prefer to dont take such a big risk.
And...
2) Is everyone totaly sure that i cant change it and unlock it ? i would really like to unlock it so i can install cm in the future (not so far future...).
Anyway, thanks to everyone and sorry for my english.

You can ask your carrier to make your bootloader unlockable I guess

No, you can't, AFAIK only in Spain you can change Unlock Allowed: No to Yes if you don't have SIM lock.

but what if i try to unlock it anyway ? did anyone tried ? would i get a bootloop or something worse ?

It wont proceed. In most cases it is not allowed when the phone is carrier-locked. If your phone is sim free then you should ask you carrier to unlock it for you

Can't Unlock Bootloader :( D2303

It's impossible to unlock...

Is it simlocked? If it's simlocked to some network you are unable to unlock the bootloader. If you unlock the phone, you will be able to unlock the bootloader

I had several phones that were sim locked and I was unable to unlock the bootloader. After sim unlocking them I was able to unlock the bootloader. The same goes for the Xperia M2, it was locked on T-Mobile MK, after unlocking the phone I was able to unlock the bootloader.

So, I assume that if I flash a debranded firmware from Xperia M2 (My cellphone can't unlock Bootloader about the "[x]Newtork 10" is locked in SimLock) may unlock the bootloader without any troubles? Is that so? Or I'm mistaken?
If I'm correct, that'd be amazing, I'd like use other ways to personalize my phone but I can't 'cause of the stupid Bootloader xDD.
Thanks!

Unfornately yes it's true how DavidMKD sayd before you need to unlock you device before unlocking the bootloader i asked few friends and XDA members and they confirmed too so , unlock the phone than you can unlock the bootloader

Debranding basically removes all the bloatware that slow your phone down. You can't sim unlock with debranding, only with special code provided by some other sim unlock sites/ebay

Exactly that. Try to enter it correctly because there is a limit on how many times you can enter to network unlock code. If it doesn't work on KitKat, downgrade it to 4.3 and enter the code. I had similar problem where I was unable to unlock on KK but on 4.3 worked fine.

Well, about that, I have a "plan", or, better said, a contract between the carrier and the cellphone, so, I must wait for two days to complete the "legal" contract. So, after that, I guess that I can unlock the device and then, unlock bootloader.
Thanks for everything!

Hi
To sim unlock you need unlock codes , there is no free way yet to sim unlock the S7 , flashing a different firmware with Odin or a custom rom will not unlock it

My phone is already unlock. If i use odin or flash new rom will it still stay unlock ???

You people are foolish even more than me. I wanna abuse you but can't.
If your device shows Bootloader status unlocked allowed 'yes'
Then goto unlockbootloader.sonymobile.com
And select device modle and enter emi number and fu+k yourself and get an unlock code.
And use experifirm to flash any regions firmware even global too.

Please keep your temperament low, Mister.
And thank you for "misguiding" people. I unlocked bootloader, downloaded a ton of roms and none would flash. Each one of them results in errors. Downloaded any custom roms available, most go into bootloop while some wont install even.
Relocked bootloader and still wont install OTAs so I am stuck with stock MM with no possibility of getting Nougat because on SO-01H Nougat update is OTA only and there is no FTF available anywhere.
Thanks again. And please dont swear on public forums.

I am sorry for my misbehave with you people but keep one thing in mind and remember that forever I never misguided anyone in my life and here which I told you about unlocking the device was absolutely perfect ? and that was the only thing I told you and that's a childish work....
I think you're a jeffal jalwatri person

Thats OK.
I have no idea what jeffal jetwari is, but rest assured your advice was acted upon and it made me lose too many hours trying to fix it. No ftf's for other variants work, not even the global version, no custom roms work and there is really not much of a benefit having unlocked the bootloader. So please only advise on something you have experienced personally.
