Apply adapter , check ID with SW, then with utility. Results like above.
Man ID here are correct, for EON it is 0x7F 0x1C (see datasheet) , results are in different form.
Allow erase function in utility. Wait timeout. Come back to Willem SW and blank check.
Read guide

i wait for ERASE and when complete i exit
and i check blank flash memory not empty
part 1 memory is not empty
but part2 is empty and blank check is ok
