Cannot read ECU Flash

[magnet]

Okay, there i s a local workshop in my country that provide reflashing service for Subarus. Weird thing is, the cars that got reflashed from that workshop, the ecu can't be read afterwards.

Any idea what the tuner could have done to make the ecu unreadable to other people? Below is the error message i'm getting trying to read the map.

I tried on the 06 JDM WRX and 04 WRX STi EDM, both was flashed from that workshop. Green test mode connected, jumper block connected, you can hear the fan.
