Pentair Easytouch 4 to 8 reistor hack no longer works?

[Neto]

Hey folks, I got an Easytouch 4 and would like to update it to an 8 but after adding the 1k ohm resistor at the board, its not recognized as an 8. Could it be that pentair caught this hack and now its preventing it?

Got help from @ogdento and had to remove the J23 jumper on the board and perform an update to make it an Easytouch 8.
