CRADLEPOINT CBA850 WITH MC400LP6 MODEM (SIERRA MC7455)

[kelteknw]

Good afternoon all,

Im trying to enter engineering mode on this modem and I cannot for the life of me understand why I keep getting the error message.

I was finally able to use the livedvd to access sierrakeygen myself, however when ever I send the:
AT!OPENLOCK=[response from generator]

I get "error"

step 1.
atterm
ATENTERCND="A710"


step 2.
AT!OPENLOCK?
it spits back the challenge code

step 3.
I enter the challenge code into sierrakeygen
it spits back generated response

step 4.
I send command back to modem:
AT!OPENLOCK=[response from generator]
"error "

error every time, am I missing a step?

it should be sent like in the image below with quotes
That image/tool is using the OPENMEP so change yours to OPENLOCK if that is what you are doing.
