Unlock bootloader Xperia J

[mikaaa]

Hello,

I have a Sony Xperia J. Recently I asked my the code desbloquio Bootloader, I was granted. I performed all the steps to proceed to unlock, but I can not do the most important. My mobile phone does not react when I open a command prompt and type in the necessary commands.
What should I do to change this? The Rooting status is the following: Bootloader unlock allowed: NO. How to change Bootloader unlock allowed: YES?
Thank you beforehand.

You can't - This would have been locked by the network and not Sony - I take it this is or was a contract phone - If you want to root then Google on your phone Towelroot - Then open the site via your phone click on Lamda symbol and install - Run the app and click on Make it rain - If it worked your phone will reboot then install SuperSU from the play store and reboot - You should if all went to plan have root

First of all, thanks for the response. Yes the mobile phone was purchased via contract, if I ask the telephone operator, they unlock? Depending on the root, I already did. Just wanted to even now proceed to unlocking the bootloader, since I already have the code, so I can not get into fastboot.

No once locked by the operator I don't think or I've never heard of it been unlocked

but you can still try rooting via the above method or visit XDA for other methods which may result in rooting with a locked bootloader

I do not need root, because I have already done. However I appreciate the same.
