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
