You got the answer, first unlock the bootloader, then flash whatever you want https://youtu.be/ZkBLrn0Dzt4

Like year ago i unlocked bootloader to make root, and install CM Lollipop, after like week sony released official lollipop update so i locked bootloader to install official update. Now i wanted to unlock phone again and install CM Nougat, and flashtool tells me unlock code is wrong. Now i remember i didnt backup keys. Is it possible to unlock or i blocked bootloader forever?

You should unlock your bootloader with fastboot. And if you didn't backed up, it doesn't matter atm.

Hi,
First be sure you have your M2 in Fastboot mode.
Then I suggest you to request a new code to be able to unlock your Bootloader again here:
http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
as you use the one prviously used the first time you unlocked your M2.
Regards.

"Device is already rooted" means that your bootloader is already unlocked.

The key won't change as its calculated with the IMEI which doesn't change.
I can say I am having the same problem. Additionally, typing oem device-info or oem lock gives me a "..." screen that would never gone. Typing oem unlock blah blah show the same results as above.
In the service menu, my phone shows boot'''' unlock allowed instead of boot'''' unlocked.
I follow the guide of xda to unlock the bootloader but the final step sent me an error like this:
FAILED (remote: unknown command)
finished. total time: 0.003s
How i can unlock it now?
