The flashlink updater toggles back and forth from bypass to remote starter often with EVO One. Doing anything where I'd like to edit or do something with the remote starter side, on remote starter mode, the leds all light up momentarily for couple seconds and then the operations fail. I can trick things around by selecting "special unit" which appears to toggle the modes for the moment. But I can't do anything such as edit options or update firmware on the remote starter side. Everything on bypass mode works fine. I'm able to update the firmware there. I did a search and found some old workarounds to pull out USB and back, but all that did was lose the connection and the application stated that it can't find the updater.
addon: I tried to flash another evo one immediately after and that module had no issue. So that probably rules out the flashlink updater and cable. I made sure the connector is seated correctly. If it's anywhere important, all the LEDs blink 25 times on the non-working module, whereas the working module did not blink at all.
