Hi guys.

I'm having a new phantom 4 pro introducing error 0x020103 during upgrade.
I heard there is a .bin file to solve this problem but I could not find it.

Can someone help me?

Hi, Josjr, I had shared the link to the .bin file via PM. Please follow steps below.
1. Power on the drone, ensure it is not upgrading yet;
2. Copy the file to the SD card, insert it into the drone;
3. Pay attention to the camera indicator, it will change from red/green light to solid green, the whole process might take 1 minute;
4. Once it finishes, update to the latest firmware.
Hope it helps.

thanks!!!!!!!!

thanks!!!!!!!!

Hi, got your PM, please copy the file to the root of the SD card, it would be better to just leave the bin file in it.

Thank you.

Hi Ryan, I would like to help, I had PMed you the Dropbox of the bin file. But please notice that it can only solve the same error code for Phantom 4 Pro and Adv. It won't work if it is not the same case. So please confirm it first. Thank you.

Hi idinabdi, could you please share the screenshot of the error message that you got for a double check? Look forward to your reply.

Sorry for the late reply, Hatem. The error message that you got is not the same case as the OP.
Please try to update the firmware again by the DJI Assistant 2, you can wait for the DJI Assistant 2 prompts you to update after connecting. If the error persists, please kindly click the "Upload Error Log" and provide me with your DJI account, I'll try to double check your case with the engineers.

I'm running into a similar problem with a brand new Phantom 4 Advanced. The DJI Go 4 app says: "Battery signal error. Please check the battery connection.". The battery level shows an overall voltage, but 0% battery life and no serial number or firmware version or anything. When I try to refresh the firmware from DJI Assistant 2, I get the error code: 0x020b03 alongside a battery error. I have tried the following:

-Discharged the battery completely and recharged to 100%
-Restarted the DJI Assistant 2 app, the drone, and the DJI Go 4 app
-Uninstall and reinstall DJI Assistant 2
-Factory reset using DJI Assistant 2
-Firmly push the drone battery into the drone as it is powering up
-Tried with and without a micro-sd card
-Tried powering up with the drone connected to the DJI Go 4 app with the OTG cable
-Tried firmware refresh from DJI Assistant 2 app from a Mac computer
-Tried firmware refresh with another microUSB cable

Any Ideas?

I have same problem as OP. Very frustrating. may I have the .bin file please?

Thank you.

I have the same problem. Can somebody share the .bin file with me please?

Please, please can you help with the same fault as I cannot even get DJI assistant 2 to re flash the original firmware. It comes up with the same error code as mentioned here. Can you help me with the use of that bin file please. Many thanks to all. You have been a great help to my friends as well.

Cheers Dave

I am getting error code 0x020b03 after trying to refresh P4P firmware to 1.05.0600 and now drone is beeping constantly.  DJI Assistant 2 gets to exactly 29% every time then fails, saying "Battery update error.  Please disconnect and re-insert the battery.  Aircraft will try repairing automatically.".  Please help!  Would love to try this .bin file/SD card method ASAP   Thank you!

Hi, I have the same problem. how can i get the .bin file?
Thanks
