So i got a new inspire 1, now forced to upgrade, followed the instructions, and it sat for 45 mins, ipad said updating etc, but never changed from 0% for 45 mins, then stopped, i can't do anythign with it now, it is flashing yellow, my controller no longer sees it, and i am sitting here looking at a brick.

Power the craft down.....Power it back up.......Power it down...... Read the .txt file on the micro sd card, if it says "cancel", you're good to go.

If not, delete the .txt file and try it again.

cheers steve, back on track. after 45 mins then crashing, talked to dji support, told me to go ahead and update controller, and it will be fine after 45min, which is strange, made no real noise etc, got hot, but did what they said, and its working again and says its latest firmware. just a bit scared now to fly it! haha. really stoked their help instantly helped me, not used to that.
