I’m trying to update the firmware of RC7630, by run the one-click tool download from [https://source.sierrawireless.com/resources/airprime/software/rc76xx/rc76xx-firmware-release-10,-d-,0/#sthash.O27ZknIX.dpbs](https://source.sierrawireless.com/resources/airprime/software/rc76xx/rc76xx-firmware-release-10,-d-,0/#sthash.O27ZknIX.dpbs)  
I want to connect to DOCOMO so downloaded _RC76xx\_Release10\_DOCOMO\_7630.exe_

But, it returns following error message when running the update tool:

Thank you for advice, but seems no help.  
After typing “AT!BOOTHOLD” I got a OK response and then the module is disconnected from PC, looks like the AT command is working, but the update tool give the same error as before.

After AT!BOOTHOLD, module should be in DM only mode which is download mode.  
So there should not be any AT command port
