I haven't flown or used my Phantom 3 Advanced drone in over 9 months. I charged the batteries and transmitter yesterday afternoon. I fired it up last night. All seemed well. The alerts told me to update the controller. I did. It said update successful please restart transmitter.. Well it didn't power on after that..   I did the C1/Other button on the right/power.. It will turn on but doesn't find my iPhone 7plus.. What next? Is there a way to undo the update?

We're sorry to read the troubles. Please make sure the RC is fully charged, then turn off the RC, hold the C1, C2, Record button and toggle the ISO dial at the same time, then turn on the RC, and connect it with APP to update from overall status.

It won't power up that way... It does however power up using C1/shutter together...

Could you upload a short video of the issue? We'd like to check the exact status and see whether it can be figured out remotely.
