I get a similar msg.

Running SDK from Linux (Tiny Core)

fastboot fired up fine

But got similar message after following Sony step-by-step.

./fastboot devices

then tried

./fastboot -i etc.

RESULT:

FAILED: (REMOTE: Command not allowed)

Any ideas?

Is there a different tool I should try another utility?

This Z2 is a Verizon release...and I noticed Sony site mentions some Z2 devices cannot be unlocked.

Is this an evil empire block?

Bootloader Unlocked Allowed : Yes

and fastboot working, detect my phone.
I already tried with 14,15 digit IMEI but result are same as the output bootloader key is same

I have issue using this method as well as trying to use flashtool. Both doesn't work. For fastboot I get into the command prompt and it's just stuck on waiting for device. In flashtool it can't find my device and tells me to reboot the phone. Any ideas? BTW my phone is rooted does that have something to do with it?

you cant adb bootloader unlock unless you have added/modded some adb files
(only aplies to z2 btw)
(yes fastboot and flasmode too you need the files(try developer.sonymobile.com)

try flashtool from flashtool.net
install drivers first before trying

Still don't work after downloading again. Anyone else got it working willing to help out? I've tried going through Sony developer again and it doesn't work. BTW my handset says bootloader is unlockable.

have you got the drivers, adb files, adb installed with fastboot n flashmode and do you have the files for those


you can get all these files from sonymobile or adb download


of course you can try the easy way to unlock which is USING FLASHTOOL
