I was able to successful fdt the spk file and the card is acting like it is working. However when I try to upgrade to sierra Generic firmware 02.24.05.06 I end up in LPW with IMSWITCH=1 set. I have restored to the spk version 01.08.07.00 and I am NOT in LPW or IMSWTICH=1.
@danielwood do I need to download ubuntu live 18.04 for your script? My other laptop is ubuntu 16.04 and I have a live usb with ubuntu 16.10. Do you think your script will work with those versions of ubuntu? Should I change the VID, PID, USBCOMP before using the script?
@panachoi what utilities did you use to upgrade to the latest generic? Sierra exe and the fdt/fdt2 do not work for me, leaves the card LPW and IMSWITCH=1.
I think I am close but not sure what combo of utilities will let me upgrade.
I am trying to get the generic firmware on the 7455 so I can connect with sprint.
EDIT: I think I am in some kind of boot loop . I can briefly putty into the 7455 before is recycles.
Here is what I can pull before I get disconnected:

@danielwood maybe my only hope is to try your script?
