Firmware Failed to Update or Install on P4800

FAQ #2959 Updated February 22, 2018

Question:

I tried to update the firmware on the P4800 and it failed. Now the unit does not respond.

Answer:

When a firmware upgrade fails and / or the P4800 won't start up, re-do the firmware upgrade through the front panel RS-232 port (instead of the rear panel RS-232 port). Force the firmware upgrade by going to File menu and selecting "Firmware Upgrade."

This is the only known instance where the front panel RS-232 port acts differently than the back panel RS-232 port.

If this still does not resolved the issue, contact Shure Service to have the P4800 repaired.
