and now i'm inside the editor...

if it says that it can't get the DeviceID string - that probably means that there's no reply from the bootloader
this can happen if the x0x is running the firmware, or if there's no bootloader at all

"(auto) unknown FW" <- this means that c0nb0x failed to autodetect the firmware, which can happen if you are skipping the normal procedures, which happens when the x0x doesn't reply in any of the expected ways (or doesn't reply at all)

and then how do you solve this situation?
I do not understand anything ...
I need specific files? software? Drivers?
link they please

I have an idea: if I remove the chip firmware that does not work well from my xoxbox ... I buy one on the internet and the replace it??
then does it work??
you can do this thing?
where I can find it?

yes, basically if your cpu has gone corrupted (that's my diagnose) ... you can buy another one
you then unplug the old cpu from the socket, and plug the new one

willzyx sells them: http://www.willzyx.com/products/atmega1 ... controller
x0xsh0p too: http://www.x0xsh0p.de/sh0p_e/template/index.html (type Mikroprozessor in the search bar to find it)

before using c0nb0x my xox worked great ...
Now why did this happen??
I can not explain it! conbox recognizes the port ... but then it stops! xox did not played in any func

the USB works independantly, because it's on a dedicated chip (the small FTDI chip which is surface-mount on the IO Board)
so it will always be "recognized" by your computer, even if the x0x cpu is broken or not functioning

as for why this happened - i can't explain exactly
but flashing firmware is a delicate process
the cpu has 16 kilobytes of flash
both the firmware and the bootloader share this space, and if the bootloader is not write-protected - it can get overwritten or corrupted

in my experience so far, it seems the x0x cpus are never write-protected, sadly

Antto in your opinion, if I buy a new chip firmware and I mount it on the cpu, then return everything to work as before?
what do you suggest I do?
thanks for your time!

to clear any confustion ... "firmware" is the software (program/code)
"chip" is the actual component (the micro controller, or CPU as i called it for simplicity)
so "chip firmware" makes no sense

if you wanted to ask whether buying a chip from one of the two sites i linked to earlier would help - yes, hopefully
a new chip will have a working bootloader (and firmware)

however, i cannot guarantee anything
it is possible to corrupt the bootloader again, it's always possible (since usually it's not write-protected)
it rarely happens, but it does :?

if you know someone who has an AVR programmer, and knows how to use it - you could ask him for a favour to try and fix your chip (by attaching it to the programmer, erasing it, and programming the bootloader on it)
otherwise buy a new one which comes with the bootloader already on

yes, that's the right cpu, but, you should be aware that these are general purpose micro controllers and you can buy them from many places, however, they usually come "empty" .. in other words - there is no bootloader by default

the x0xb0x uses a custom bootloader which is specific to it so you have to buy that chip from someone who has specifically programmed it with the x0xb0x bootloader

so you should make sure that this chip comes pre-programmed with the x0xb0x bootloader .. so ask the seller

because otherwise you will buy an empty chip, and you will end up having 2 non-working chips, which is not what you want

yeah

or search on your own, there could be more places to buy from
it should be from someone who is selling x0xb0x kits and parts, and you should still ask him explicitly whether the chips come pre-programmed with the x0xb0x bootloader
