Won't boot after replacing CPUA on TAC32

I just replaced a CPUA board on a Tac 32 Hydo. Now the LCD display is just black blocks. When I attempt to use the USB to upload the job file the STAT led keeps blinking rapidly

You need to have the job file in a folder named update in a folder named tke. Once you have that, press and hold reset and while holding reset press and hold udl. Let off the reset while holding udl. After a few seconds the stat light should blink slow, slow, fast, fast. Once that happens let go off udl and software should load. Controller will reset when finished.

You also need a generic software file in the update folder if the board has never had one loaded
