[Q][Sola] Why can't unlock bootloader - Sony Xperia P, U, Sola, Go

Hi guys,
I've got an Xperia Sola wich is not SIM locked.
I've tried to unlock it with the official way but i've got a problem : When I do : *#*#7378423#*#* => Service info > Configuration > Rooting Status : I've got "Bootloader unlock allowed : No". And I don't know why.
I've contacted Sony but they says that is a Sofware security and I may ask the Android Comunity.
So i'm here : Does anybody have an idea of why I've got that "security" and how i can delete it ?

Hi people of XDA,
I'm looking forward to unlock my phone's bootloader, but unfortunately in the service menu, the status of my phone says "Bootloader Unlock Allowed=NO"
Is there any way to change the "NO" to a "YES"?
Additional informations:
My phone is SIMLOCKED to a carrier
I have the 16gb model (E2306)
I have already contacted Sony, but they can't do anything
Thank you very much!
I think u can not do anything.
No, you can't unlock it. There is no way to do that with Bootloder unlock allowed: NO.
same for me, i have the e2303, is there a way to root it? or there's something we can do?

Bootloader unlock allowed : No - Xperia Z2 help please

Hi guys, as title says I have Xperia Z2 phone that tells me that
"Bootloader unlock allowed : No".​
Can I somehow unlock the bootloader ?
Even if I have to pay I guess its Ok if its not too expensive.
Have you simply tried to unlock it anyway just to make sure? I just succeeded in unlocking a Z2 today which was missing the bootloader unlock allowed status.
