omg, it works again!
first of all, i can confirm that update is not possible with third party cable (this is not good because we need to take care of original cable now)
second - update is not works on Mavericks even with original cable. i was able to mount Kasina, delete original firmware and copy new firmware. but then device became unresponsible. and only way to recover it was to use updater utility.

i think all of this must be covered in info section about firmware update.

The core functions are in a protected memory space so any firmware update should not prevent the Kasina from functioning. The update would simply be unsuccessful. At least that is the plan.

The manual updates have been in progress over the last few weeks. I don't know if they will make it to other languages any time soon.

USB cables are rated differently for power and data.

Not true. The USB cable included with the Kasina is a very standard USB-A to Mini-USB-B cable. There is nothing special about it. That being said, there's no guarantee that a 3rd party cable will work as some are made with less-than-good tolerances. We included a good cable so that you wouldn't have problems, but I have updated my firmware with many different cables I have lying around and it's been fine. Again, though, I have found cheap cables in the past that would not work with my external hard drives and things. You should definitely make sure you always buy verified cables if possible.

second - update is not works on Mavericks even with original cable. i was able to mount Kasina, delete original firmware and copy new firmware. but then device became unresponsible. and only way to recover it was to use updater utility.

I know there are some issues with updates on Mac. Interestingly, it's flawless on Windows. We are definitely looking at ways to make the firmware updating on Mac as flawless as on Windows.

So, the firmware update utility did work for you on Mavericks? Man, a lot of Mac users lately which is good (Mac is my primary platform too). Mac has a tendency to create all kinds of hidden metadata files that pollute drives. This has to be at least part of the problems when coming from the Finder. Another microcontroller platform I use has the exact same issues with firmware updates on Mac.

I didn't say there was anything special about our cable, just that there are USB cables with different ratings.

Actually charge and data are pin connections so if the Mac recognized and mounted the Kasina then it is a data cable but maybe not a good one. Hard to say.

third party cable was not completely noname. it was supplied with bluetooth speaker and i used it many times with different devices. do not know why it can't work with Kasina.
