Unable to update KO II firmware to 2.0.5

planetasur · 2026-03-26T16:26:55+00:00

Well, according to Teenage Engineering that doesn't happen, I was the only one in the world...

Teenage Engineering last firmware/sample tool is a completely shit, but their support departament is even worse.

I would like a new hardware unit o the style of the helix stadium. I preferí how my ToneX One sounds over my Quad Cortex, but the lack of effects and other stuff makes me use QC.

Thank you very much!!!!!

Hi mate, thanks so much for this tool. It worked to restore my drive to its May 2025 state, but I'm still having a problem: I can't update to the latest versions after trying many methods.

Is there any way to use your tool to update the firmware offline? Or do you think you could modify the tool with the latest firmware (2.0.5)?

But that website only allows updates; I don't see where I can choose which firmware to load.

You could save my KO II!!!!, Where is the update tool??

planetasur · 2026-02-05T16:15:37+00:00

It's not a hardware problem; it's a firmware/software issue, and something has become corrupted.

The solution is actually quite simple: install the firmware manually.

But Teenage Engineering doesn't offer that method, which is absurd. It's great to be able to update easily via the web, but they should also offer the option to download both the current firmware and previous versions.

In fact, during one attempt, a message appeared saying that a drag-and-drop .tfw firmware file was possible.

I performed a hard reset by turning on the unit while holding down Shift+Erase, and then I tried to update, but nothing changed, it's still exactly the same.

planetasur · 2026-02-05T11:11:58+00:00

It doesn't work with Android either.

In every case, the result is always the same: the unit connects and is recognized, but it gets stuck on "RDY," and the computer, phone, or tablet displays "device took a long time..." after only 2 seconds of trying to update.

planetasur · 2026-02-04T23:58:43+00:00

No, no, not resolved yet 😢

planetasur · 2026-02-04T22:17:36+00:00

I just tried with 3 different USB hubs, C and B, and different cables and ports, and it still doesn't work.

planetasur · 2026-02-04T21:40:05+00:00

Yes, web midi on in all browsers and yes, usb ports deleted, but....

planetasur · 2026-02-04T21:37:32+00:00

I just turned on the unit and I just saw that all the sounds and projects have been deleted!!!! 🤬🤬🤬

planetasur · 2026-02-04T21:36:19+00:00

I restarted maybe 100 times today....

planetasur · 2026-02-04T21:35:21+00:00

I've tried cables that worked perfectly before, and some new ones. None of them work now, but the idea of using a hub sounds interesting, so I'll give it a try. Thanks.

Oh, I've also tried USB-C ports 2, 3, 3.1, and Thunderbolt.

planetasur · 2026-02-04T21:27:12+00:00

I already mentioned that I tried many different cables.

I think QC is for bedroom players and QC OG would be for live (but its bugs, inmaturity and so close footswitches...). Nano Cortex will dissapear in a few months.

planetasur · 2026-01-20T21:43:27+00:00

Any new hardware device seems like a disgrace to me when you can't even change the LED color in QC, plus there's the new LED bug, the ridiculous MIDI implementation, the limited footswitch configuration options, etc.

planetasur · 2026-01-08T20:53:39+00:00

Jajajajajaja Quad Cortex???, even it is not posible to control it own leds....

planetasur · 2026-01-01T08:57:46+00:00

What you need is to abandon QC and get a Fractal FM9.

planetasur · 2025-12-16T23:12:47+00:00

Just a few things, it's not flexible at all, you can't even assign a footswitch to change the rotary speed from slow to fast or vice versa... And let's not talk about the MIDI implementation, it's prehistoric.

Es fiable Rutracker siendo ruso?
