Hi everyone,

I am trying to upgrade a MC7710 to the latest firmware and it has decided to die on me.

I was previously on:  
Firmware: SWI9200X\_03.00.11.00AP R4152 CARMD-EN-10527 2011/12/20 14:52:19  
Bootcode: SWI9200X\_03.00.11.00BT R4152 CARMD-EN-10527 2011/12/20 14:44:40  
Hardware version: 203F1000 (this may be reporting wrong)

And I was planning on going to  
Firmware: SWI9200X\_03.05.24.00ap r5792 carmd-en-10527 2013/05/02 13:35:47  
Bootcode: SWI9200X\_03.05.24.00bt r5792 carmd-en-10527 2013/05/02 13:28:17

I installed all drivers and then proceeded with the upgrade which failed. I attempted again and it failed again.

This is the error I am getting on a Windows 7 Enterprise 64 bit:

The only thing showing in device manager is the: “Sierra Wireless DM Port (COM 14)”

Is anyone aware of what I am doing wrong or what I can do to recover from this?

Considering it is able to switch modes I am hoping it is still recoverable.  
Thanks for all your help.

Here is a bump to see if anyone has any ideas?

I have got my company contact to request support from Sierra Wireless but so far all they have done is send a link to the software that I used to brick device.

Anyone at all? Is there any recovery method anyone knows of?

QMI all the way.

Hi all,

For reference, I have resolved my issue. It appears I was using a poor quality USB PCI-E dock. I had a colleague visit from another country with a different style dock and it worked first time.

Thanks.
