Trying to update the 34461A DMM Firmware from V2.17 to 3.02.
The unit appears stuck showing "Updating Firmware, do not power down."
It has been more than 1 hour??
I disconnected the USB key (formatted FAT), powered down the unit.
It came back with an error message saying the FW update failed, running FW 3.02 and a beep every few seconds...
The message appear after each start-up.
Lucky for me the keypad was working, so I downgraded back to FW 2.17 using another USB stick (FAT32).
That worked no problem.
The FW update utility does not detect the 34461A connected via USB unless the IO Library is installed... Not sure I saw this was required...
I installed the FW Version 3.02 over USB using the update utility, everything seems to be working now.
I hope this could help others with similar issues.
