ix6780 printer bricked after resetting wast pad count

[karama]

Hello guys. I have a Canon IX6780 printer works good until a few days ago. Code 1700 appears and I used reset software to clear the wastepad count but I forgot to place a paper to print after the waste pad count resetting process. In stead I just pressed the power button to power off the printer. And then I cannot power on the printer again. I tried to press and hold power button and stop button to hard reset but in vain. I took out the motherboard and dumped the eeprom with CH341A programmer but I don't know which part should I modify to make it work again. The printer eeprom dump attached below, it seems corrupted during the resetting process. Anyone here familiar with this situation and knowledge of this issue? Any help would be appreciated.

Win Rar cannot open the archive. 7 Zip and Total Commander also fail to open it.

Sorry for the inconvenience. I will upload zip format file or binary bin file if possible tomorrow.

Btw the motherboard uses a Winbond RAM chip. I borrowed a motherboard from my neighbor and noticed the same model motherboard used a different RAM chip. I used CH341A programmer to read the SPI chip and wrote to the corrupted chip of mine, then I soldered back to my motherboard still failed to power on the printer. I suspect the contents of these two SPI chips are different due to RAM chips drive code.

Well, he could ... just sharing that 7zip is a really useful utility for decompressing a lot of different compression file formats...

Winzip is the devil incarnate though... Evil, nasty developerssssss. We hatez them don't we preccioussss
