H27U2G8F2C　 poroblem with VP-998 Reply

 I have a problem with VP-988 and Hunix H27U2G8F2 (nand flash)

I use WL-TSOP48-U1 adapter.
After several readings of the same flash check sum is never the same, the last 4 hex characters are always different.

Loading the bin for programming has no check sums that existed in earlier version of the wellon programmer.
It is a very useful option.
Programmed verification is never ok

Software　　 Ver.: 4.7.2(7.8.2017)

Best regards
