@[NUT] yes he did, he was the content of the PM I sent you

It's how I got here in the first place :good:

@craoul

first of all, boot your phone and connect it to usb. Then run adb devices in a CMD window. Note down the serial, you will need it.

Okay, in the flashtool folder, check if

[FLASHTOOL FOLDER]/custom/mydevices/[DEVICE SERIAL]/ulcode.txt

exists.

If not, create the folders along the way there and then use notepad or something very lightweight to create the ulcode.txt. Put in the code, be sure to enter the code without the 0x, so just the code as it came from Sony. Save the file and start FlashTool.

Now the BLU button should offer to unlock again, but there is a difference: it will now use the serial and code to wipe the lock using the FT relock/unlock method. Without that file in place it will use the fastboot method.

Good, glad it helped :highfive:

Thanks also go out to @Androxyde, he gave me a run down of how it was supposed to work. Thanks buddy!

@gregbradley, excellent support dude, kudos to you for that! :cowboy:

No worries, That's what I do.

This one had me baffled though and now I have learned something new again...Its the spirit of XDA-Developers.

Hi,

I have used the previously mentioned method to unlock the bootloader.

Everything using the flashtool seems to work fine, says unlock finished etc, with no errors.

However, in the service info menu on the phone, still says: Bootloader unlock allowed: yes.

Is this right?

Hi,

I had previously unlocked using the instructions from Sony.

I then relocked using Flashtool a while ago.

I then tried to unlock using Sony method without success.

Please find below a copy of the log output:

If you're referring to the one about the folder structure, I think from the log output you should be able to see it was done.

If not I did follow what you say.

@craoul

first of all, boot your phone and connect it to usb. Then run adb devices in a CMD window. Note down the serial, you will need it.

Okay, in the flashtool folder, check if

[FLASHTOOL FOLDER]/custom/mydevices/[DEVICE SERIAL]/ulcode.txt

exists.

If not, create the folders along the way there and then use notepad or something very lightweight to create the ulcode.txt. Put in the code, be sure to enter the code without the 0x, so just the code as it came from Sony. Save the file and start FlashTool.

Now the BLU button should offer to unlock again, but there is a difference: it will now use the serial and code to wipe the lock using the FT relock/unlock method. Without that file in place it will use the fastboot method.

hey thanks for this info!

I will talk to @Androxyde and try to fix it at FlashTool level!

In flashtool we dun even use the TA backup we did, which infact contains DRM keys:)
