Hi everybody. I've just updated my Kemper Head to the latest operating system (PROFILER Operating System 7.1.2 Release for Head), coming from OS 6 "stable".

I've tried to import the new presets following the OS 7 Addendum, in particular entering the System Preferences and pressing the Factory Presets soft button. Unfortunately I don't have that button (it was present on OS 6) so I decided to import presets manually using the Rig Manager.

Since I was concerned about the fact that the button was missing (maybe something went wrong during the updating process?), I've tried a fresh install from the recovery menu (init flash, then booted directly from the pendrive in order to flash the kaos.bin file). Everything went fine but the Factory Presets soft button is still missing.

I've then imported manually all the OS 7 rigs and presets via Rig Manager.

Anyone experiencing the same issue?

By the way, I've already logged a ticket.

Oh, that explains everything. Thanks Timo.

Would it be possibile to downgrade to the previous stable version of the OS, including rigs? Unfortunately I cannot find the binary anywhere

I tried importing presets from System menu but nothing happened.

If I perform the init flash before doing that, after finishing the importing task the profiler reboots but, again, no rigs.

I did not try importing presets for upgraders, though. I’ll do it and let you know.

Thanks

Yes, and actually it works If I manually import them but the point is that I’d like to have a clean system that works as it’s supposed to be. I can’t tell if this behaviour is due to the latest update or something going on on my unit. That’s why I’d like to downgrade e start over

Hi, I’ve just installed the new firmware release but unfortunately factory rigs are gone. Tried importing them via System Menu, performing init&restore as well as init flash from maintenance mode even though I know this is not suggested by some of you. Tried reinstalling kaos.bin from usb pendrive booting with pages button. No luck.

I would like to restore the previous stable version of the firmware but I don’t have it anymore and Kemper site does not provide it anymore.

Can someone please share it to me? Version 5.5 would be fine I guess.

Thanks in advance

I see, thank you. In the meanwhile I’ve opened a ticket and they replied it’s normal as I’ve described It. Good to know

Hi everybody, I have a question for you.
Last night I was browsing through some rigs using the Rig Manager, thus the chosen profiles were presented with the black solid background on the Profiler display.
Looking at it from an angle (my laptop was just beside the KPA, on the right, and I was sitting in front of it) I realized that the display exibited some sort of faint vertical lines (less contrasted) in particular on the black box where characters composing the rig name were present.
Sitting in front of the KPA and looking at the screen, it is perfectly fine with no stripes at all.
Contrast/Brightness settings as per factory settings.
So the simple question is: could be a bad symptom? How about yours?
