9780 can't install any app

[ Edited ]



I have an important issue with my 9780 device. For any application we have done, it's impossible to install it either from javaLoader or web Loader.


  • From webloader: it displays an error 909: "Echec de l'authentification de l'application"
  • From javaLoader: it displays: "Error: invalid signature"


But I can install the same cod to my Torch and Curve devices.

I tried reinstalling the device software (os, plateform



Is this issue known?

Thanks for any answer
