That happens if you start the Stage and press a particular button combination simultaneously.
What happens, if you pull the plug and restart?
If you should end up in System Maintenance, pull the plug once more and start again.
I have the same problem. I don't know how to fix it.
When trying to upgrade my Kemper Head to OS version 7.4.1 up, I got the following message:
nanoboot: burnFromUSB()
ERROR: unable to locate firmware file on USB device
failed to update firmware
what have I done wrong?
No Idea to fix that problem
Are you following the steps as outlined in the How to document included in the download package? Or are you trying to start from USB memory stick, which is an undocumented procedure?
I'd tried to start from USB memory stick like i always did before
Meanwhile Kemper support team has helped me and everything works again (probably the intermediate step over version 7.3.2 was missing).
Hi Franz,
I have the same issue! Please can you describe the steps to solve (gerne auch auf deutsch)?
Thanks a lot!!

I got this error code when my USB stick malfunctioned (I have never had one die while using it.... a first !).
The solution is to replace the bios.
Get a new usb stick. Format it in you pc to fat32
Place the kaos.bin (from the zip file you download from https://www.kemper-amps.com/downloads/6/Op…-System-Updates) into the root of the drive.
Make sure the Kemper is switched off.
Put usb stick into kemper. Press and hold both < > switch the kemper to tuner.
It'll reinstall the bios. it takes a while. I think that this has happened enough that Support should start helping guys here in the comments where the bios has gone during an update.
I got the info from https://www.soundside.de/support/KPARecovery.htm
Thank you
I've seen this error code a few time over the last couple of weeks both here and on Facebook.
I think it would be cool if an official fix / steps for when this happens could be posted by someone from kemper when someone posts this issue.
I tried 3 different USB sticks and could not revert back from 7.5 beta to 7.41.
Got the same message.

Try the 7.3.2 bios. Its available for download in the 'older software versions' of the download page.
When my usb stick failed and borked my kemper during the recent 7.4 update debacles, I put this version on, and then let Rig Manager handle the updates.
