Does the EM9190/EM9191 have a **FORCE\_USB\_BOOT** pin? I want to enter **9008 mode**. I forgot the **AT!ENTERCND** password, and I want to try restoring it to default. Are there any other methods?

have you checked specification for the pin assignment?

You might need to contact distributor to level-3 unlock the module in order to set the AT!ENTERCND password

I can no longer contact the original dealer. How can I recover the password?

then i don’t think you can level-3 unlock the module to reset password

BTW, do you have any business contact with any Semtech FAE?  
if yes, you can discuss with him to unlock this module
