Make sure you pick 256k
we did all settings were correct but some faults in the program/windows fuckt it up 
Will check everything today thank u guys for your support :-)
if it works again will let u know

I have tried to upgrade one jala's but during flashing there was a error in Atmelstudio
I guess the chip is now empty Usb still working and sees the unit but its not hashing any more
do you guys got a solution to reprogram the chip ?
Please pm if you do or post this it on this thread

I didnt have to unplug the jtag cable it started mining after a less than 1 minute pause even with the cable and dragon plugged in and on. this is why a heatsink is absolutely need to flash, its starts ASAP after a flash (at least with the dragon).
This might be off topic, but in terms of the LED's what do they mean? Because two of my Jalas running have only 2 LEDS, where as this new one that just came into today, has 4 LEDS, all flashed with the same firmware (1.2.5CK)
the ones with the 2 LEDS - 1 LED in the front, and 1 LED in the back next to the power plug
the one with the 4 LEDS - 1 LED in the front, 1 LED in the back next to the power, and 2 LEDs next to Atmel chip

Yikes! I can tell you from experience that once the magic smoke comes out mysterious little boxes with blinking lights, they no longer tend to work. 
I'm sorry you seem to have bricked your unit.
this happens if you dont use the hardware accordingly, so be sure to always check that the pins are correctly mapped. I'm sorry you seem to have bricked your unit.

Look at Q10 (the middle FET on the second row) - it looks like desoldered from the heat, so you may have had overvoltage all over the board ... or it's just from the picture's angle
Looks like the FTDI chip has fried. That is bad news, because it pretty much means you won't be able to get your unit to talk to a PC anymore, assuming that is the only damage done.
Was that the only chip that smoked? Something must have shorted it out to get that to happen, maybe a dodgy USB connector, loose metal somewhere on the board...
The FTDI chip is hooked to the 3.3v power supply, the Atmel labelled chip and the USB port only, so the point of failure has to be one of those, or somewhere between them all.
I suppose there is one possibility, if the Atmel processor fried and managed to dump current through the FTDI chip that could cause smoke, but chances are both would have smoked and it wouldn't light up anymore.

Maybe it doesn't like the fan unplugged
Where's your heatsink?
