Firmware won't upgrade . Help please

[Swazimavic]

Good evening.
Please could someone help. When I try upload the latest firmware on my phantom4 using the DJI assistant 2 it freezes at 55 % and the error code says 0x022403. I have also tried using the DJI go 4 app but it also freezes at 99%.. I have tried several times using both methods with the same results. Any help would be greatly appreciated. Thanks in advance

Try going back into the dji go app, with everything turned on and connected. When you go into camera view you will probably see a red warning message (disconnected or weak transmission or similar). Tap that message and you should then see a screen with a red triangle and beneath the opportunity to upgrade the RC firmware. Whilst that is doing its thing, connect up your drone to assist2 and you should see the latest firmware to download. When both are finished, turn it all off and then on again. Next thing to do is the revised IMU update, and hopefully all will good with the world. Credit to @JohnnyD913 for saving myself and many others for posting up this tip.
