You need to lay out your own dump, it will not work with strangers.

Because you didn't set and write the status register (0x88, 0x42) after dump was written.

Yes its now working, thanks a lot!

With a huge delay, may I have detailed instructions. I have located the Chip on the main board. Should chip get removed? ]How to connect the mainboard 8 pin chip to CH341A hardware? I guess USB goes to Laptop and software?
