EM7455 upgrade states success but does not work

[Paul Gildea]

Hi,

I'm trying to upgrade an EM7455 to the latest Verizon firmware. The libqmi
firmware updater returns that it is a success, but when the modem reboots
it is booting into ATT, so the modem comes up in low-power and is unusable.

Subsequent upgrades yield the same result. Switching carriers and switching
back to Verizon also does the same, other carrier images work fine. I don't
have physical access to the modem so can't take it out to reflash it. Any
idea of how I can solve this?

!IMPREF:

preferred fw version: 02.33.03.00
preferred carrier name: VERIZON
preferred config name: VERIZON 002.079_002
preferred subpri index: 000
current fw version: 02.32.11.00

current carrier name: ATT
current config name: ATT_002.070_002
current subpri index: 001

fw version mismatch
carrier name mismatch
config name mismatch

Thanks,

Paul
