The 88 I have seen is not the right one. The RX/TX is not flashing and it needs to be. There is a method that requires a slide switch put into one position and slid back within a few seconds.I have also seen the 88, but there seems to be no way to get past it like maybe it is just to test the display. I suspect that some of the switches on the radio need to be in certain positions to start with, maybe. I thought about making a spreadsheet to keep track, so I don't try the same things over again. And maybe make a video so I don't forget what I just did when it works.
