Hi all,

Just got my sk-360 all installed in my trex 500 and proceeded on to installing the software and hooking the system up via usb,following the instructions.

i noticed the firmware was 1.03 and the latest version is 1.10, so i went to update.

heres the problem...

when installing updates,the green bars got about half way when all of the sudden i dumb thumbed and thought i could turn of my tx because it was down to 9.5v...well as soon as i did that the window closed and another one appeared saying "UPDATE FAILED".

now every time i go to update it to v.1.10 i get an immediate "update failed"......????

what do i do?

Possible no recovery . . .
Hey MapleLeafs,

I am pretty sure that the firmware upgrade for the SK360 is like the firmware upgrade for any other type of hardware. There is a loader portion in the firmware that allows it to load and upgrade to the next level of firmware, which is what you were doing. If it did not get to the point where the loader portion got loaded, when you go to upgrade it again, the code needed to load the next version will not load, which is the problem you are having. I do not know if I explained it so you can understand, but basically, you are screwed. You will need to get in touch with the company and probably have to send the unit back. There might be a chance that the company has a back door where they have a special way to reload the firmawre from scratch (in the field), but usually it has to go back to the company where they have a machine that will program the EPROM with the loaded. Not good news, but at least you do not waste time trying to keep upgrade the firmware, but definitely call the company as soon as you can.

Regards . . .

Try scaling back a few updates, and then go up one update at a time. I had to roll back to 1.03 or something, then 1.04, then 1.05, then I was able to install 1.10, mines was doing the same thing at first.
