Teletype update firmware help (solved)

Hi,
i bought two ansible to work with my teletype.
So i need to update the firmware of my teletype.
i tried… and now have a black screen…

i’ve installed the drivers for the AT32UC3B device. ok
i ve downloaded the new firmware.

After i’m not sure to understand all.
when it 's been said run cmd as Administrator. i suppose that it means to run the update_firmware.command file from the ms dos prompt (c:) ?

when i do that it opens a text windows saying:
" #!/bin/sh
cd “$(dirname “$0”)”
dfu-programmer at32uc3b0512 erase
dfu-programmer at32uc3b0512 flash teletype.hex --suppress-bootloader-mem
dfu-programmer at32uc3b0512 start "

after i cd to the the dfu-programmer folder an try to execute from the msdos prompt :
dfu-programmer at32uc3b0256 erase
dfu-programmer at32uc3b0256 flash whitewhale.hex --suppress-bootloader-mem
dfu-programmer at32uc3b0256 start

Sometimes it seems to work,and sometimes it says that dfu-programmer is not a command…

i 'm completly lost, and lost a teletype…

thanx for your help

when it says “dfu-programmer not a command” it seems you are not in the dfu-programmer folder.

cd to dfu-programmer folder and run:

dfu-programmer at32uc3b0512 erase
dfu-programmer at32uc3b0512 flash teletype.hex --suppress-bootloader-mem
dfu-programmer at32uc3b0512 start

the second group of commands in your post are for white whale.
