Congrats! I hope my upgrade works today as well. 4 more hours until I go home.
Your update method is not possible on a P4. You must be referring to a P3A or P3P.. There is no bin file for the P4 listed on the DJI P4 support page. All updates are made thru the app or assistant 2 software.You DO NOT have to update the bird first. I just updated everything this evening, no issues. First, I did the controller with tablet over wifi, tablet connected to controller with USB cable. The bird is not even powered on. Next, put the BIN file on the SD card, fed it to the bird, powered on the bird, updated no problem. The controller was turned off. I then checked the SD card txt file, all was good. Wiped the BIN and txt file, reinserted the card in the bird, turned on everything, ready to fly. I have done this so many times without any issues, yet I keep seeing posts with all kinds of failures.
If you are using the DJI Assistant app, then you are not going to fix the problem. The app does not work properly and DJI knows that.

Such an important feature, you would think this is a priority to get working correctly.
This is painful. Follow exactly the steps, downgrade everything...no problem...then upgtade bird first then RC with absolutelly no problem, all Success but still No Signal, no Image and "Firmware is of the lastest version" "Abnormal" "Aircraft encoder error".
Everything else seems all good, Aircraft responds RC perfectly, Green lights everything... no signal, no image.
I bought far way from home since in Brazil doesn't have official dealers, I don't know what to do anymore.
Your images of the process should be stickied. They are by far the clearest visual of how everything should be hocked up and working.Ok I have had a breakthrough with updating the RC and Bird. I had to use my girlfriends iPhone 6s in order to update. I don't know what the problem is but if I try to update on my iPhone (6s Plus) I keep getting the continue download problem where it gets stuck on 0%. I have no idea, anyway, I am going to plug my phone back in now and check all my settings, calibration e.t.c Out of interest what device do you have ?
I will plug my phantom into my laptop in a sec and see if it finally detects the firmware on DJI assistant 2. Good luck with yours later. Pics below.
