USB stick not recognised for update (recognised for backups etc though).

Laurens · Sep 4th 2014

Hi,

my first post around here, as I'm still fairly new to the Kemper, but I'm having an issue with updating already, unfortunately.

So, I formatted a 16GB USB stick on my computer, put it into the Kemper to have it formatted for the Kemper, put it back into the computer and put the update file (kaos.bin, IIRC) in the correct folder. All as instructed in the update folder.

Then, when I plug the USB stick into the Kemper (doesn't matter what mode it's on), the Kemper seems to get stuck. The tuner no longer moves, I can no longer adjust parameters, or whatever. When I switch from the tuner to the browser (e.g.), it just acts as normal again and recognises the USB stick; however, I get no option to update the Kemper. I can backup rigs and whatnot just fine.

FWIW; I'm using the unpowered Rack-version, it's on 2.4.something and I'm trying to update to the latest firmware.

Kind regards,
Laurens

1) Format the USB stick on the Kemper
2) Plug USB into computer
3) Copy kaos.bin into OS folder
4) Unmount USB stick
5) In browser mode, plug in USB stick and wait for a few seconds

The Kemper is sometimes finicky about USB sticks, but since yours is being recognised by the device, shouldn't have much trouble getting this done.

Yes, "Format the USB stick on the Kemper" is always a good advice in this cases.

The OP had the stick formatted on the Kemper.
I'd try again (re-format the stick).
If it fails, use another stick.

As mentioned by Ingolf, I got it formatted on the Kemper. I'll try again though and insert it while in browser mode and get back with my findings.

Yes, I read that. I was just giving a step by step of what to do now. Since the USB is recognised by the Kemper, that at least is a good sign. Sometimes you may even have to just take out and plug in the USB stick again, or copy a file again, etc, and wait for a few seconds for the Kemper to give you the update option

The way mine always seems to work is to switch the system off with the USB in (new firmware already on the stick) and then turn it back on.

I tried again and it didn't work again, but then I used another stick and with that, it worked. Really strange, because the other one works with any device (from PC to Mac to PS3 and whatnot). Ah well, got it to do what I needed, so that's the most important thing.

Could it be the formatting, though? I formatted the other stick on my Mac in Mac OS Journaled, and the one that worked was an old one I had laying around that was formatted on Windows in FAT32 or NTFS (not sure).

Good it works now. I've seen this happen a few times with different sticks.
I'm pretty sure it's nothing to do with the the existing format as they're re- formatted in the profiler.

The one that doesn't work is an Emtec, for future reference.

Thomann use these: https://www.thomann.de/gb/thom…tick_kemper.htm#bewertung
I'm having the same problems but if they use the toshiba 8gb I reckon they're a good bet. Fingers crossed.......

I have a no name 15 year old 512mg USB stick/Mp3 player that works like a charm on the Kemper to update the KPA and back up etc.

THe Profiler can only deal with sticks that were FAT32 formatted.

This doesn't seem to be the case hjscheffler?

FAT is only used with some outdated sticks with a maximum size of 2GB. These sticks cannot be FAT32 formatted. Apparently the Profiler works even with these old sticks.

Yep
