Good morning, I am new to the forum, or almost new, I have been registered for some time, but I had never transmitted a problem. I have already installed quite a few hwfly v4 on Oled, but this one has given me an unknown problem, when I turn it on, everything works correctly, atmosphere starts up fine, but the volume button - has stopped working. I don't know where to look or what component is causing the problem. I have tried to remove the chip and in ofw it gives me the same error. Would someone know what the error could be due to, what component can I look at and how to try to solve the problem, with that problem when starting up it doesn't give me the option to enter hekate and so I can't do the emunand. Thank you very much for your answers and greetings to all.
