A customer company has developed an LTE router device using the RC7630 and is in mass production. During use after mass production, normal module booting is not possible due to power stress or external effects, and when connecting the module and PC via USB, only the Qualcomm USB Driver (dload interface port) is connected.

In this case, is there a way to save the module by reinstalling F/W? Or if there is a related Qualcomm tool, please let me know.
