Hi, I have a phone sla-l22, I can not get the code to unlock the bootloader through the programs hcu-client and dc-unloker, when I received the code, the error "Read bootloader code fail! Device must be repaired before this operation!" . What to do?

Must repair device as empty board on HCU before you can read the code from it, seems it was modified or not fully repaired before.

How to fix it?
