At least. don't use the -F option, because that probably will brick your radio

That error, "Target doesn't answer", is covered on the product page under the FAQ tab... relevant section pasted below:
AVRDUDE Error: Target doesn't answer
This error indicates a problem between the programmer and the 9X. It has nothing to do with the USB connection to the computer. It is generally caused by the following:
  • You don't have the 9x powered on. This programmer requires the target (the 9X) to be powered.
  • One or more of the spring pins is not making contact. This could be a simple alignment issue, or the screws are too loose. Flux residue or oils from your fingers could prevent a signal, so cleaning the pads and pins with 99%+ alcohol can make the difference. Inspect the pins and pads
  • Your 9X is a so-called "V1". See the "My 9X is a V1 (or V2 or V3)?" in the pre-sales section above.
  • A defective board.
Unfortunately, there's no simple way to test for a defect other than ruling out the other possibilities, so go over everything three times then please contact us for further assistance.

Generally very good advice. NEVER use the -F option!

However, in this case, it can't cause a problem because a connection to the target doesn't exist :) It can't solve the issue either, so NEVER USE IT!

It could have caused a problem if he used it when flashed the radio the first time. Remember he said that after flashing it went blank and never responded again..
A bricked radio will display the same error. Not saying it is the case here though..

What settings do you have in companion?
Exactly what file did you flash?
What chip does your radio have?

Matzeeg3, did you go through the troubleshooting items I posted?

My guess is you didn't have the radio on. Flashing an unpowered target can erase it, but not program it.

Well, I only see a picture of Avrdude's output,not one of the configuration settings..

Please try adding -B 100 to the extra arguments field. Try doing a reading of the eeprom or firmware instead of trying to flash the radio..

It looks like you might have some connection problem. Could you please post a picture of your 9x mother board.
Also check that no pogo pins are bent on the smartieparts board, or that their springs are locked and not making contact.

You could also try eepe instead of companion.. Please download it at www.er9x.com

Some info here about new processor if needed: (viewtopic.php?f=95&t=3819&p=74105#p74046).
Do you know that your processor is bad ? :?:

Would be better to upgrade to the Atmel - ATMEGA2561-16AU chip: (viewtopic.php?f=95&t=3819&p=71554#p71554).

is the atmega2561-16u compatible to OpenTX? (not eepx or er9x)
Pictures attached

I have no idea if openTX supports the m2561. This chip does allow for more features. But I believe openTX is not being developed or maintained for the 9x stock board anymore. Er9x is.
It doesn't even support some features like the multi protocol module.. I personally think that you would be better off with er9x..
Can't see anything wrong with your board :(

The major differences I already told you. Er9x is still maintained, so you have more chances of having new features, or support for more hardware implemented.
Er9x supports the 4 in 1 Multiprotocol module.
Er9x supports the addition of extra hardware like extra switches.
In my opinion er9x has a much better user interface and it is much easier to navigate the menus and find the options we need without having to scroll through many menus before you find the one you want. But this one is my opinion of course.
if i decide to stay on opentx will the atmega a post will be the right or do i need the 16a Version? i don´t find informations for that
Atmega128-16AU
