That's exactly what I was saying. I've never had this problem. But I know enough to follow the damn instructions and fix it instead of complicating the crap out of things and posting nonsense. CTRL+C is the only way you break CFE boot, by the way. And, you have to be quick. I've always started by hitting the keys before applying power, because they boot that quickly.... and I was lucky a couple of times to get it on the first try. A boot loop could mean more than one thing, though, but whatever. Good luck, fix the dang thing, or not..... send it here if you can't seem to figure it out, or not. You're wearing me out.

So sorry, I can't help the ADHD and the fact that I'd probably already have the thing de-bricked instead of doddling around wasting time. Feel free to send it here, if you can't do it.

At this point you can’t recover it using serial. Only jtag.
Not really worth it unless you are doing it for the fun of it.
You’d have to flash a good cfe using jtag and then you can use serial to flash the firmware.
