Every time i try to put the iso in the usb with etch droid a error message says that the writing process is stuck,

I tried 2 linux distro and is the same so i assume is not about the distro and may be something about app compability cause some times the app has troubles even before the "stuck" error appears things like crashing or redirecting me to the menu of the app all of this happens with the same steps pressing the button to write the image onto the usb select the iso file and then or loads and "stuck" or crashes or just back to the main menu

(yeah english is not mi main language sorry about errors or lack of technical language or if is hard to understand me)
