Hello- sorry if this is already part of another thread- it seems to be a slightly different problem I'm having.
At one point last year my OP-1 was starting up on a black screen with a small speaker crackle. With the advice of this forum I saved it by starting in TE boot mode and installing new firmware.
I'm now having the same black screen problem. HOWEVER- now when I load a firmware file onto the OP1 and press the com key as instructed... nothing happens! The OP1 just sits there on the instructions screen as if i didn't press the com button. I've tried factory reset and formatting drive to no effect. I have tried firmware file versions 218, 220, and 225. My OP-1 will not seem to continue the install process on any of them. I am wondering if anyone has come across this problem? Any help is greatly appreciated. I am considering sending the device in for repair but being as I am short on funds- thought I would reach out as a last attempt!
