Aircraft locked. Update needed. Does not update!

[IceFireSoul]

I do not know what to say. I recently got the new DJI Phantom 4 Pro Plus. Great machine, but...!

Day 1

It was flying okay after activating. I updated the remote. Kept flying. Remote found a new version again.

Day 2

I was able go fly once. On the second try it all ended. I am getting ""Aircraft locked. update to the latest version." . I missed a wedding. Went to buy an otg cable as I didnt have mine with me ( never ever needed it on the field). Updated the drone and now...

It keeps saying that there is an update AND it cant update - the update button is greyed out. W*F?

It may meen that the RC and AC are not on compatible revs, did you update the AC too? You might also try a factory data reset, I would pull any SD card out of the RC and check the Erase SD card checkbox.
