[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.

xperia zl c6506 bootloop after bootloader unlock

Hello,
I had root and custom recovery installed. Everytime I try to unlock bootloader with code provided by sony, it fails and when I retype it, I get an okay message. Once I restart phone , it wont load past the design logo and just keeps restarting. I flash back to stock, try the same procedure and it does it again. What am I doing wrong?

Are you sure that your device says
Bootloader unlock allowed : YES in serice menu?
recheck it.it happened with my xperia pro which bootloader is not unlockable.
& make sure you don't have Bluestack installed in your pc.

It says yes and I have no idea what blue stack is. I am on windows 7.

[Q] Help me unlock the bootloader of Xperia m dual!

I'm using Xperia m dual c2004.I tried to unlock the bootloader. Several times using the procedure given in the Sony developer, did everything correctly. But the phone goes into a bootloop after which the only option is flashing the stock rom.
I tried unlocking the bootloader the otherway by using flash tool but it doesn't have my phone's drivers. And the link to download them doesn't work anymore (found it in a thread)
The are no roms for lb for my device (plz tell me if you know any)
I checked my bootloader status by going into *#*#bla bla code then service tests and security And the service Status was active which means bootloader is locked.
When I go to service menu and config my phone's rooting status is showing bootloader unlocked.buti don't think it is ul but it just has the Permissions.
Please help me I'm not able to flash roms because of this.

When you successfully unlocked bootloader you should go to bootloader mode with key combination when restarting phone and install custom recovery. Naturally without loaded drivers in computer it has no sense to try it.

BOOTUNLOCKED allowed : YES
means you can unlock the bootloader by KEYS. (provided by sony) (you can request them)
