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.
