Dfuse - Unable to find devention device... Bad fir

Sorry if this has been posted before but i searched and none seemed to have this problem. I have a 7E im trying to upgrade.

Im running Win8 64 and have only got the v1.41 of Dfuse to open up. When i plug in the tx windows chimes to say its recognized and ive updated it to the driver that included with dfuse. When i open Dfuse, it seems to recognise the STM Device in DFU at the top and displays the vendor id etc of the tx. However the upgrade button is greyed out and in red at the bottom it says "Unable to find devention device... Bad firmware."

Any tips to get past this issue?

Can you upload a screenshot?

Ahh, that would probably be it then. I cant seem to get 1.5 or above to work on win 8 64 even by changing the compatibility.

I will keep trying.

Okay got the 1.5 version to work by removing my keyboard usb! All flashed to dev3.0 now.

Is it normal for the tx to make some little noises once its flashed? It almost sound slike a computer hard drive thinking.

I took the rf shield off with the intention of doing the diode shorting to get greater range but fk me that think is small, and im not a good enough solderer to do it. Didnt want to short either of the very close diodes. Of course it couldnt have been one of the bigger ones thats out in the open a bit more could it!

The diode must be shortened - does not matter if it stays on the board or not. So you could use something what is called "Leitlack" in German - a liquid color containing metal parts which will make an electrical connection when dried. You just have to draw a line between both ends of the diode.

would "Silver Conductive Wire Glue" from ebay be similar?

Looks as if it should work, but I have no experiences with this.

So after playing around with the tx i noticed that on the screen it says under the battery voltage "150 mW", now is that standard on the 7e or have i managed somehow to actually do the mod? I havent adjusted the tx.ini as i didnt think it worked and i aborted my attempt. I did get a tiny ball of solder on an adjacent diode but i checked and it didnt look like t bridged to the other end. Hmmm.

Are you using the stock radio module or an added module when you see this? What are you flying?

What does your tx.ini file show?
