Hubsan Official Forum

Hello, greetings, I hope you can help me, I have a problem trying to update the firmware of my drone h501s, I had done it before and had no problems, but now if I have problems, download the latest firmware for my h501s from the official website of hubsan (https://www.hubsan.com/support/files/upgrade/H501S%20Latest%20firmware.zip), and followed the instructions in this video (https://www.youtube.com/watch?v=wWTfFXs695c ), but I have a problem, when trying to do the binding, as shown at the end of the video my h501s does not do what it should do, keeps the lights off and after a few seconds makes some sounds, it's as if it had stayed in the step that is shown in this video (https://www.youtube.com/watch?v=wWTfFXs695c) at minute 12:50, what can I do?

Same issue. I have an H501S (Standard) and I bought and installed the 14 dbi panel antenna. Then I followed Hubsan's YouTube video (https://www.youtube.com/watch?v=wWTfFXs695c&t=795s) to upgrade the firmware. When I get to the third step, I get a timeout error.

Having the same issue too. Trying to install "H501A-FC-V1.1.46" but keep getting the error "update error".

Solved my issue. I realized I have the H501SS not the H501S. The video for that is : https://www.youtube.com/watch?v=hk9Cgg-qP0M
I had to just use the H501A Upgrade Tool to upgrade the FC to 1.1.36. It gave me a timeout error, but i just had to repeat it a few times and it finished successfully, and my drone is back flying now!!!
