    I know people were having some issues with a “boot loop” on version 8.6xx but we have been running on 8.6_511 (bios 1.2.3 and 1.2.5) without an errors.  We are running WMS 3.1 as well.  I recently tried to update one of the 3040’s to version 9.0_xx and initially it worked.  I loaded the Citrix package and tested, and everything worked (even the VPN), but I could not get a resolution higher than 1920×1080, I tried on a 4K monitor and Dell Ultra Sharp 2560×1600, but only 1080p.  So was a double checking everything in the config within WMS, made some minor tweaks…and then it has no picture at all, after the initial Dell plash page, the monitor(s) go blank (you can see the screen “shutoff” but not go into sleep mode).  We can hit F2 and F12 to either adjust the BIOS and we even tried a restore using the Dell USB Boot.  We tried down grading to 8.6_511 which despite working on BIOS 1.2.5, still no picture.  Is there another menu using a function key that we can get to, to actually check the display settings, reset them?  We have tried a BIOS reset, and the Factory Default setting in the BIOS, still nothing.  We tried a second 3040 (I know…) but upgraded the BIOS to 1.2.5 running 8.6_511 no issues.  Then we allowed it to upgrade via the WMS Config to 9.1.1131…and it appeared to be “working” (the upgrade at least), but after it rebooted twice (loaded the Citrix and Zoom packages)…same thing as the first one…reboot loop.  The Dell logo comes up, disappears, then you see the black screen backlight shut off, but the monitor is still on…then after a bit it just reboots, you see the Dell logo again…and it just keeps repeating.  We have tried loading from a USB, not that is appears to be the issue, but we even tried to downgrade the BIOS and despite the check mark in the BIOS allowing us to downgrade the BIOS, when you boot with F12, select BIOS Patch…it shows 1.2.5, we select the new/old BIOS from the USB drive (we tried 1.2.4 and 1.2.3) it flashes super fast about analyzing the file, but it is so fast, I had to record it in slow motion on my phone and see what it was saying…it jumps right past like it is in the incorrect file(s) and won’t allow us to downgrade the BIOS.  As you can see, we have tried a lot of things…kind of out of ideas…I was hoping maybe someone had some of the same issues and might be able to help.  Thank you.

    Two things to test.
    1. attach a different keyboard (different brand)
    2. try to flash the unit with the USB Firmware tool and a Merlin image.

    We can certainly try a different keyboard?  Have you seen issues like this with keyboards?  At this point, I am willing to try anything.  We did try the flash the unit using the Merlin ThinOS, we tried an 8.6xx one and the newest 9.1311 and still nothing.  I did see where you can wipe the local storage devices, it appeared to be for when you may be no longer using the devices…if we were to wipe the device, can you still restore via USB?  The device is “ping-able” once it boots, but we aren’t able to VNC into the device.  Thank you for the suggestions, we can try a different keyboard…we have been using the Dell keyboards that came with the 3040’s.
