I received my prime yesterday. I was happy ^^
The first thing I did is updating firmware through the connectivity kit. The calculator entered recovery mode (v13), the progress bar progressed fine, when, at about 4/5 to the end, the connectivity said "update failed", and the machine did not respond at all. I pushed the little reset button on the back, and now the machine won't turn on at all...
What am I supposed to do next, please ? :'(
EDIT : I managed to start the recovery again ([symb] + reset) after a few try.
EDIT2 : and launching Updater.exe did the rest. Sorry for this useless thread
