Hi,
i have an APX120 with a solid red light. I read other Posts on this Forum and established a serial Connection to the AP. I cant break the auto boot even with a powershell script which sends 1000 inputs per second. I read in this Post https://community.sophos.com/sophoswireless/f/discussions/142129/trying-to-unbrick-my-apx120 that you it can help to short SO/SIO1 to break auto boot. Unfortunately i dont have the necessary knowledge to know where those pins are.
The serial output says:
