The installer downloads and checks the complete firmware set before changing your board.

Recover or resume an installation
If the screen is blank after preparation, that is expected: the temporary bridge is running.
To enter S3 download mode: hold S3 BOOT, tap S3 RESET, then release BOOT. Use the S3 controls, not the C5 controls. Select the USB JTAG/serial device when asked.
Restoring only the S3 does not update or verify the C5. A complete install and startup check are still required.
A direct connection.
Your browser talks to Cerberus through USB. Board identifiers and progress stay in this browser unless you save a report. Reports include board MAC addresses; keep them private. No account, desktop installer, or expansion board is required.
