Bootloader status: Unknown?

I've got a Z2 from friend which is both Sim locked and Bootloader locked with Bootloader Unlock Allowed: No.
However, my friend did something with hex editing to change this status from No to Yes. He didn't make a TA backup. Now it says Bootloader Unlock Allowed: Unknown and phone has no service and camera crashes. Any solution to bring the phone back to life?
