To the guys who have had problems... can I ask exactly what happens if you plug the program box into the ESC, what comes up on the screen? Anything, or is it blank?

I've just been testing out on a spare esc I have. A couple of things I have noticed.

Firstly, it took two attempts to flash the latest V1.13_131106 firmware to the program box. The first attempt spacked out in the middle of the update, resulting in just a row of white blocks across the program box screen. Closing down the V3.43 software, restarting, and then reflashing the program box solved that problem.

Secondly, with the program box now with V1.13_131106, I updated the esc to V3.2_140627. The update completed fine, however if you turn the esc off, and then turn it on with the program box connected, the program box displays the "Please Upgrade Software" and I'm unable to turn the esc off at the button. This may not be the same problem, but it's the closest to what I can replicate for a bricked ESC.

So, whats the fix. It's simple, and I already mentioned it. Downgrade the program box to V1.11_120331_V3. Unplug it all from the esc, start up the V3.43 software in program box mode, then go to the upgrade option and select that firmware. Click upgrade, and it will downgrade the firmware on the program box. If it stops mid stream, just shut down the software, unplug the box, plug it back in (getting the blocks) and restart the process, making sure to reflash with the correct V1.11 firmware.

Plug the box into the esc... and bingo, now it all works again. I strongly suggest everyone to try that first, and see if it fixes the issue.
