SOLVED - Help.. New firmware has broken my Kemper

steveness · Feb 26th 2015

Hi

I've just upgraded to the latest firmware 3.0.0.10845.. all appeared to be going OK until it reloaded after completing all the checks.

I got the following 2 messages (see attached)

Now the kemper just hangs with the Kemper Profiler message on the screen..

Can anyone point me in the right direction on how to raise a ticket ?

Cheers
Steve

Format a flash drive. Put Kaos.bin in root. Boot Kemper while holding < and >. Problems should go away.

Best

I'll give it a try.. thanks

steveness · Feb 26th 2015

Alas I still get the same messages after booting from the flash..

steveness · Feb 26th 2015

I've managed to boot it back into action using previous release of firmware.. I've raised a ticket with support so let see what happens.

Thanks for letting me know how to boot from flash, much appreciated

Cheers
Steve

Welcome. Maybe try redownloading 3.0 and trying again? Possibly could have been corrupted?

steveness · Feb 26th 2015

Hi.. Yeah, I've just tried that, and a different flash drive.

I can load up v2.7.3 fine, but if I try v3 it fails every time with the same software error

Hope they can sort it for you!

Try the new one posted (3.0.0.10856).

steveness · Feb 26th 2015

Hi Mike, has this only just been made available ?..

The version I used I only downloaded a couple of hours ago !.. I will try this one now

steveness · Feb 26th 2015

damn.. nope, 3.0.0.10856 gives me a software error too..

Try this put the FW in the root directory and not the Update folder turn the kemper on holding the 2 page buttons down this should load it. I had this problem about a year ago when I did a FW update

Install or reinstall the firmware
Switch the main knob to off
Download the latest KPA firmware
Get an empty fat32 formated USB stick
Copy the unziped firmware file 'kaos.bin' to the root folder of the USB stick
Plug the USB stick into the KPA
Press and hold both '<' and '>' keys
while still holding both keys - switch KPA to tuner
Something like 'booting and installing' will be displayed
Wait until the firmware is reinstalled.

Hi Guys

Yep, tried all of that but I still get the software error with V3.

V2.7.3 boots and works fine using the above method.

Hans has just contacted me from support, so fingers crossed we should get to the bottom of this issue soon.

At least I'm not stuck with a dead kemper as V2.7.3 is working fine

Thanks for your help guys

Cheers
Steve

Sorry that didn't help let us know what fixes it when they sort it

Zhuravlik · Feb 26th 2015

I think the downloaded firmware is corrupted . Are you tried download it with another browser ?

regards

steveness · Feb 26th 2015

I'll try downloading using chrome, but I've downloaded 2 different versions of 3.0 tonight (3.0.0.10856 and 3.0.0.10845) and both had the same result

I'm just trying to upgrade from V2.7.3 to V2.7.4 as I type.. once I've done that I will try again to v3
