Problems with obtaining the code unlock bootloader P9 Lite.

[prist256]

Good day. The problem is as follows. I purchased credits for getting the unlock code for the bootloader, the code was received, when unlocking for some reason the phone restarted, and the DC-Unlocker crashed. When you enter the Fastboot mode, it says that the device is unlocked, but it is not possible to install a custom recovery via the fastboot, because the "command not allowed" error is issued. At the moment, I have a phone with the word "unlocked", but it's blocked by the fact. The unlock code did not have time to save, because the DC-Unlocker was automatically closed. Dear administration, I ask for your help.
Sory for my bad english, i use Google Translate.
