i have 2 p3p. my main p3p has the latest fw. my backup has 126 fw and no camera! the main p3p has come up with esc error, i believe it is front left motor. have ordered a set of four motors to replace them all. so meanwhile i took the camera off of the main p3p which has the latest fw and installed it on the backup p3p which has fw 126. it flies just fine with rc 158 and dji go app 283. in the "about" tab it does show the versions i just mentioned. now, here is the problem: i went to update the fw from 126 to 140 but the log file says failed as the fw is older or same as existing fw. this obviously is not true as it has 126!!! i have tried 132, 140,160, and even the latest fw but they all give the same result. i am wondering if the camera that came from my main p3p which had the latest fw 196 is the cause of not being able to update fw on backup p3p with 126 fw??? any ideas would be appreciated.
