--- Quote from: BloodyCactus on July 01, 2014, 06:56:14 pm ---did you test the usb stick by saving a screen image to it to make sure the ds4k can see it properly? on my ds2k, I had to wait a bit before putting the usb stick in, too quick and it did not seem to load. tried again, waited like 30 seconds after the button presses then put it in and it recognised it correctly right away. --- End quote --- The stick works, I saved a png screenshot. I also waited a couple of minutes, still channel one only goes solid without first blinking. When I used DS4000update_00.02.01.00.03.GEL, the channel 1 LED did blink first and then went solid. After a couple of minutes all lights lit. I restarted and nothing changed in the firmware or TB. I did use riglol first though. Don't know if thats the wrong order? In short: DS4000Update.00.02.01.00.03.MrKrabs.GEL on a stick didnt work for me so far... Cheers |

I tried another USB stick and then it worked. Prolly something in the firmware loader doesn't agree with certain USB interface chips. |
