[Solved]Bootloader unlocking problems: FAILED (remote: Command did not succeed)

[kistigun]

Hi Guys,

So i bought a second hand XZ(C6603) as an upgrade from my XS. The previous owner told me he had unlocked the bootloader and then again relocked it(he used the BLU function in flashtool). Yesterday i wanted to unlock it again but somehow i cant get it unlocked anymore. In the service menu it says: "Bootloader unlock allowed" YES meaning i can unlock it.

I've used flashtool and adb both with the same result:

14/055/2013 22:55:31 - INFO - Device connected in fastboot mode
14/055/2013 22:55:36 - INFO - Unlocking phone using key XXXXXXXXXXXXXXXXXX
14/055/2013 22:55:36 - INFO - ...
14/055/2013 22:55:36 - INFO - FAILED (remote: Command did not succeed)
14/055/2013 22:55:36 - INFO - finished. total time: 0.035s

XXXXXXXXXXXXXXXXXX= the unlock code i got from Sony

I've all ready tried whiping & reflashing it with the flashtool(.423 frimware) and also repaired it with PC companion but after that i still get the same results

Anyone got some advise for me? Could it be a driver related isue(btw i'm on win 7 64)?

Are you sure you correctly type the key? I also was in this situation, but after ctrl+c/ctrl+v the code more accurate the unlocking went ok...
Try to reinstall fastboot drivers

Do you have any branding on the phone from your carrier, are you sure rooting hasn't changed status to yes by accident.

Are your drivers correctly installed (load up flashtool and connect your phone in fastboot and it will say device connecter in fastboot)

This is a common occurrence @kistigun so it could be just that (although it doesn't allow unlockable Phones to be unlocked unfortunately), but as you were informed it has been unlocked before you shouldn't be having any issues. Have you tried doing it manually using command prompts?

Also tried it with command prompts but with the same result

If it's locked by any way, is there any way to unlock it again?

You should just be able to do it the same way I would have thought, are you sure you're just not seeing the wood for the trees perhaps? And have you backed up your TA Partition before trying btw?

Pff, finaly got i unlocked! Found a German forum where someone had the same problem:
http://www.android-hilfe.de/root-custom-roms-modding-fuer-sony-xperia-z/380742-xperia-z-root-bootloader-unlock-anleitung-23.html

Had to create a folder in flashtool/custom with my XZ serial code as name. In the folder i created a text file named ulcode.txt in text file i've put the unlock code i got from Sony after that it unlocked!

Thanks guys for the advice! For now i'm going to flash the sh*t out of my XZ

Are you sure your drivers a correctly installed Toby? Have you tried the command prompt way?

What version on XZ do you have C66??

If you have tried command prompt way and you are 100% sure drivers are installed then you have a locked bootloader
