hi
i have get an spark with a L3D Cube. So the spark works with the default programs but its impossible to connect to the WiFi. So i have read that it maybe is a good idea to flash the deep update. I installed the spark line command on Ubuntu 12.04 like its told under “install on Ubuntu”. The line command works as i can get out (via USB connect" the id of the spark. So i tried to update but get this error:
So i don’t know what to do now but for now i can’t do anything with the spark. Did someone have the same issue or an idea what can be done?
thx for help in advance

didn’t exactly know if its correct (or how i can control it)
ipls give me a hint whats going on
AFAIK the missing DFU suffix doesn’t matter, you can ignore this, but I’m not sure if you really refered to my tip, since the command line you quoted there was actually @kennethlimcp 's suggestion.
Some additional reasons why it might not connect to your WiFi:
Possible error in credentials/security settings (set data again - PWD max. 32 char)
The Core doesn’t support 801.11n and higher (change router settings)
The Core can’t connect to channels greater than 11 (change router settings)
Check for radio interference.
If you got a uFL Core, check your antenna.
What security settings are you on (open, WEP, WPA, WPA2, Personal or Enterprise)?
But your additional reasons are good because there i have a few issues which are set in my WLAN Router. So i will change the Router and test and then i report if its the solution.
I have WPA2-PSK with AES as encryption (hope this is possible).
Do the chip need SSID Broadcast?
yes yes yes it works great - the reason was the channel and the 801.11n protocoll
so thank you so much for helping. Thiese things can be really frustrating. You don't have an error or something like that it does nothing you seat there and look in this flashing nothing
thx to all of you but especially to ScruffR
