Try to flash one of your blank chips directly in the GQ-4X4 and see if it passes the verify step without error. |

| today i've install the 29f800 and the engine don't start, i've made a recovery from bdm and now it's all ok. A friend on mine say me that i've flashed the memory without swap the byte..... next weekend i'll try on another similar ecu engine. |

Yes, some binary files may need to be manipulated before the write.
You can read the working chip and compare with your source file. |
