I have a Phantom 1.1.1 and after storing it in in my traveling case for a period of a couple of months I have recently tried to fly however I was receiving a red, green yellow indicator lights. At this time I connected my phantom to the NAZA assistant software and I was receiving an Error 25 message I am also receiving an error on the data point for the acceleration on the "z" axis. I have contacted DJI and they informed me they have stopped performing maintenance on the Phantom 1.1.1. After looking into this problem online I have found that taking out the Naza imu and hitting it on the side should fix this problem however I have had no luck in this fix. If anyone has any other information on this problem or what they used to fix the problem any help would be appreciated.
