Unable to flash my ECU?

[kaekiii]

So something interesting happened today. I was getting my ecu flashed with revo stage 2 but my ecu rejected the flash twice at the 75%-80% mark from what it seems like. Anyone experienced something similar? The revo dealer told me that my ecu might had been tampered with therefor the flash was unsuccessful but the previous owner of the car changed the ecu few months before I bought over. So I was told the only way I’m going to get a flash was to get a new ecu.

There might be a tune on the ECU which is preventing the Revo flash. The previous owner may have set it back to the stock flash, but if it wasn't actually flashed back to stock by the dealership it could be interfering with the Revo flash.
