I have been having problems trying to unlock the boot loader on my Z1.
I followed the instructions provided by Sony to unlock. I had previously unlocked and relocked the device.
However, now when following instructions again I am given the following errors:
FAILED (remote: Command did not succeed)
And after this:
FAILED (remote: Device is already rooted)
Even though it is not and service menu says,
Boot Loader Unlock Allowed: Yes
Any help is appreciated.
