One M7 IMSI locked

There is some known problem about repair security on One M7, almost always after JTAG repair. Phone is always locked. Is it possible to repair it somehow with XTC2Clip? Change IMEI, lock/unlock option not help. Some security data is stored to ID and WLAN partitions. It’s connected somehow with CPU or baseband IC. You can’t even change EMMC witout backup of this 2 partitions from old EMMC.
Any idea?
