Greetings!
I have Hubsan X4 H501S PRO, HT906T control panel. After a long break (4 months) took the flight , but found that the control panel does not receive telemetry information from the copter H501S. Produced procedure "Bind to Plane" ,but a remote control still not routinely received telemetry. Searched hints on the forums, stopped on the advice taken from the website of the manufacturer manual and files programs firmware ( https://www.hubsan.com/eur/index.php?main_page=support: H501_Upgrade_Software.zip) and update the firmware FC, TX, RX, which took action according to the firmware instructions of this model, but the procedure for updating RX is not performed. I followed the steps as in the YouTube video: https://www.youtube.com/watch?v=FxO4ID-W0No I appeared on the screen: upgrade rx mode v2 then after starting the program on the screen appeared power on RX, after powering on H501S no other information appeared. Video after connecting the power appears "select file and down", I have this information does not appear

HT906T control panel=H906T control panel

HT906T control panel=H906A control panel

sorry for mistake!

Make sure your model is not a h501s-s it has different firmware

H501S
