I have an Evo 1 and it said i needed to do a update a few weeks ago. I did an over the air update and it said RC failed. I did not have time to rerun the whole process so have not flown since. Today I turned on the bird and controller expecting it to tell me update was still needed. I waited about 2 minutes to be sure it was all connected up and had wifi and cellular data, etc. No firmware update message appeared. I am a little skeptical about trying to fly it now as i dont know if the rc will have a communication failure, etc. I went into the general settings, then to Firmware Version and it says as follows:
