The "meta USB COM port for modem handshake" is more than an error—it’s a reminder that low-level communication is a fragile pact. Two processors, speaking over copper and silicon, must agree on timing, voltage, and protocol in the span of milliseconds. When they fail, the error is not a bug, but an honest admission: I waited, I listened, but no one answered.

Leave the device plugged in, minimize the bypass tool, and immediately run your repair software using the newly opened COM port. Summary Checklist for Troubleshooting

The meta mode handshake happens only for a few seconds. If the software is waiting, but the phone has already booted past the preloader, the port will disappear. Thus, the full error means: The software attempted
