Xhorse Multi Prog Can’t Write AM29F400BB FLASH Solution

Problem:

Read am29f400bb ok but cannot write it.

I use Xhorse Multi Prog.

The error code is 11030001.

Should I desolder the chip?

Here is the Solution:

1)Select ‘Erase’ and read data, and see if all data show 0xFF

2)If so, Search for ‘7971’ and select ‘M29W400BBxxM(TSOP44)’

Write data again and ignore reminder.

Done! Hope this helps!
