Did you tried igel.com igel.com or fwu.igel.com/files/IGEL_OS_11/updates/lxos_11.04.130_public.zip fwu.igel.com/files/IGEL_OS_11/updates/lxos_11.04.130_public.zip ?


I downloaded the ZIP File and imported it to UMS. But the Import Firmware window stays empty. So im not able to select a FW to import.


Can you forward Screenshots?

(view the screenshots inside the IGEL Community on Slack, join below)


Hope they help, just let me know if you need some other’s

Steps before Screenshots: System -> Import… -> Import Firmwares


That‘s where the issue comes from. Please do the following:


Upload was successfull! Thx for your help 👍:skin-tone-2:

For my knowledge, for what kind of FW was my way to import?


You are welcome! For Profiles, that you could use new Feature sets there.


sorry to come back, but I can’t select the new FW in the Profiles, see Screenshots


No worries. You first have to update a device, then after hitting F5 in UMS Console, it should be available.


Ok, will do that…

Worked as you explained. Thx again for your fast reply


TIP: As part of your workflow for adding new firmware, spin up a VM with IGELOS OS (just select 90 day trial license) and then update to new firmware, do initial testing with the VM … Then delete the VM and remove from UMS….


I get this same error when downloading the firmware from within UMS. Firmware download of IGEL OS 11-11.04.200 failed!

Does it work when downloading the zip from myigel.biz myigel.biz and import it manually to UMS?kb.igel.com/endpointmgmt-6.05/en/firmware-archive-zip-file-universal-firmware-update-31599849.html
