content: Hello,just downloaded the new firmware software from agilent and updated it with the update tool. The UpdateTool did find the agilent device on the local internet and uploaded it successful. The Agilent 34461A processed it, booted and said, it would Complete the Firmware Update. And now it seems to be frozen in step 1 of the to steps, about 1/5 of step 1 for more than a half hour. Should i wait or should i reboot the device? I am still waiting and hoping that it will finish its Update but i am not sure.regards

content: I think only Keysight can give you qualified advise on this question unless someone else here on the board had the same issue and tried it out.In the last few weeks I have updated three 34461A's and one 34470AAll with the update toolAnd all over the network cable through TCP/IPAnd all of them went well and without any issuesIt did say on the screen, "NOT to Power Cycle" during the update from the PCBut it did not says this anymore after the unit rebooted the first timeA total of two reboots are needed for the full firmware updateSince your first part of the update went well, you might want to try rebooting.If the reboot does not help, then it will probably also not help to wait for another hour.And if all fails, .... will be interesting to read your report

content: Yes, after 3 hours i decided to reboot. Now it is not quite at the spot where it was frozen before, but i have to go to sport and after 2 hours i will see.But it is a little bit strange, i have literally changed not the smallest detail, i nearly used it as it came.Ok, i wait,regards

content: When i came home, after 3 hours, the 34461A was still frozen. I bottled again, but with no luck. Then i switched it off and draw the power connection, waited some seconds and turned it on and it made the 2 steps with the upgrade and booted without problems.Now it seems ok. *luck*

content: Not so big "luck". Even if the firmware update failed and meter became dead, it can be flashed again. Though it won't work from usb flash but only with USB connection to the PC.

content: BTW I remember that have read somewhere (likely in the update instruction) that if updating from some older version, meter won't reboot automatically while updating and manual switching off is needed.
