Yes, you said so earlier. There is clearly a language issue. :\

Please start investigating what happens with the SST flash chip after
each flashrom operation.

Step by step:

* Insert Pm49LF004 chip
* Run flashrom -r original.bin
* Insert SST49LF004B chip
* Run flashrom -E
* Run flashrom -r sst_after_erase.bin
* Run flashrom -w original.bin
* Run flashrom -r sst_after_write.bin
* Analyze sst_after_*.bin and try to find a pattern that can explain
  what is failing at each step.
