[ix6770]Need .bin file flash to eeprom and flash via ch341

[Nhinhi]

Hi everyone,

1. Does anyone have a .bin file for the IX6770? I need to flash it into a new EEPROM for my printer.
2. Do you know why, when I connect the CH341A tool directly to the EEPROM on the mainboard, the tool does not respond when I click "Detect"? If I remove the EEPROM from the mainboard, it works. How can I flash the EEPROM directly on the board without removing it?

Thanks all.
