KPA just arrived, not able to complete OS boot :-(( HELP!!!

  • Hi everybody,


    my name is Fabio, I live in Genoa, Italy.


    I've been waiting the Kpa to be released since May and eventually arrived home today.


    To my deepest disappoint it can't complete the OP boot:


    I turn it on following the instructions, the loading screen regularely appears, the


    loading bar goes up to around 80% then the screen gets slightly less lit and the loading bar


    disappears and stays that way forever, "kemper profiling amplifier" remains on the screen...


    I know that kemper team is at NAMM, so I'm not expecting instant support.


    Any ideas? Does anybody have the same issue.


    most probably it is a software problem, I don't know........ so sad right now


    thanks


    Fabio

  • Thank you for your feedback guys, really appreciated



    Joeblob: I've read it but my problem seems a bit different, I'll re-read it anyway


    Guitarnet70: I don't know, the box was nearly perfect and cosmetically the unit seems immaculate..



    I think all I can do at the moment is to wait for K team reply to my assistance request and then decide


    whether to send it back and have a new unit...

  • Hi Niklas,


    I contacted Kemper support, they told me to boot from a FAT32 formatted usb stick with the new firmware


    (turning the unit on while pressing exit), but did not worked, I reported that to Kemper support on friday and


    currenty waiting for their response, hopefully tomorrow .


    It's a bit frustrating to have this fantastic new toy and not being able to use it ;(


    ciao

  • Create an "OS Update" (written exactly like this) folder and put the kaos.bin file inside and try again. Not sure that a boot from external storage works if the OS is in the root directory...

  • Put the latest FW into the root folder of the stick
    Turn KPA off
    Hold the two buttons below the exit button < and >
    While still holding this buttons power on the KPA (but only to Tuner mode)
    Install latest firmware

  • guitarnet: I'll try that, even though Kemper support told me to put the kaos.bin directly on the root directory


    armin: already tried that and not working for me


    thanks for your input guys! really appreciated

  • not working as "will not load latest firmware" - or "will stop at 80% the next starting up"?


    If the second case than you may have corrupted rigs - try to erase the flash - as explained in my Toast ..." thread.

  • HI Armin,


    it apparently does not load the latest firmware from the usb stick, (shouldn't the kemper advise that it is booting from usb?, does some message like" firmware update" or "usb loading" apperar on screen when it load something from usb? )


    -I turn it on (on tuner) while pressing > <


    the loading bar goes up to around 80% then the screen gets slightly less lit and the loading bar


    disappears and stays that way forever, "kemper profiling amplifier" remains on the screen...


    -I turn it on (on browse) while pressing exit


    same result...


    (I tried the above putting the kaos.bin file directly on the root directory & putting it in a OS Update folder)


    ;( ;(

  • Even if you put NO usb stick into the KPA - it should display 'booting and installing form usb device'.


    All you need to do is:
    1) switch the KPA off
    2) press and hold all the time the two buttons < and >
    3) while still holding the two buttons switch the chickenhead to tuner
    4) Now you should see the display message

  • It does not display this message...


    I tried several times your procedure but no success


    I turn it on, the loading bar goes to around 80% then disappear, I turn it off, press&hold <>, switch on to "tuner"


    but still same result: the loading bar goes to around 80% then disappear...


    It might be an hardware problem, I don't know...

  • Since we are both no native speakers - it's important to hold < and > ALL the time not only to press it once and then turn the switch.
    The message will be displayed immediately - before the KPA boots.


    If you hold the keys and turn the knob and nothing happened then the keys may be defect or whatever - can you activate the maintenance mode (hold softkey 1 = top/left obove the display) while starting the KPA?

  • Yes, that button - but this will not work on all firmware versions.
    The < and > should work always - as immediately after you hold and press the buttons and then switch to tuner (before you see any boot progression bar).


    Does it display anything in case you press (and hold) the system, rig or quick buttons?
    These buttons pressed during the boot sequence reset different stuff in the KPA - this will be displayed before 80% is reached.


    If you get no other message then I expect that some connection cables are loose or whatever - you need to send this box back.
