PfSense 2.3 and Huawei E8372 - Making it Work

devianceluka

my Huawei E8372h-153 is not responding to AT^SETPORT? command. It throws ERROR only, so I cannot change the mode.

The following command is used to unlock some AT-commands, but result depends on the current firmware version loaded
AT^DATALOCK="OEM code"
I can try to generate a code for you if you will PM me an output of
AT^NVRDEX=50502,0,128 and AT^NVRDEX=50503,0,128
I do not own such a modem myself, so I can only try.

Send:AT^DATALOCK="OEM CODE"

Recieve: ERROR

Send:AT^DATALOCK?

Recieve: ^DATALOCK:1
Recieve: OK

Send:AT^NVRDEX=50502,0,128

Recieve: ERROR

Send:AT^NVRDEX=50503,0,128

Recieve: ERROR

Please reply as soon as possible, I'm waiting for you!

Send:AT^NVRDEX=50503,0,128

Recieve: ERROR

This means that your particular modem is blocking access to this command as well. Without this information I have no idea how to generate the OEM code.
As I mentioned earlier, result depends on the firmware the modem is running. Please post the firmware version you're running (available from ATI command), just for our information.

I finally got excited when I saw you could do it. Now I'm back to the starting point. :-(

As far as I know people were successful with datalock unlock on 21.xxx.99.xx.xx firmware.
I suggest to try changing the fw.

What I do not fully understand is this:

for DATALOCK="OEM code", one should input OEM code from AT^NVRDEX command correct? So it's the NVRDEX command that is not working.
all I need is OEM code? With this code and DATALOCK command - I unlock other AT commands?

What if I write a small script that bruteforces OEM code in DATALOCK command?

Thanks for still sticking here and helping. I really appreciate it!

1. The output of AT^NVRDEX command is used to generate an OEM code by a special tool.
2. Generally - yes. Potentially one can reset or change the OEM code, but this requires ^NVWREX command being working.

Andrew, how sure are you that AT^DATALOCK has a 8 digit code in it? My script, that tried every possible combination from 99999999 to 00000000 just finished and every single combination throws ERROR. Can you please help me on what to do next?

I know that some commands are locked in some fw versions. I suppose that with particular 'bad' fw version the modem may just refuse the right code. I suggest to load the generic (non-operator, not branded) firmware.

Good news, long story short: I got the OEM code and I get "OK" when I enter it with AT^DATALOCK.
But bad news is, that:
"
AT^SETPORT? = Recieve: ^SETPORT:A1,A2;A3,A2
"
AT^SETPORT=?
AT^SETPORT="A1,A2;1,2,3"
AT^SETPORT="A1,A2;A3,A2"
AT^U2DIAG=0
" = all throw ERROR

What now?

I can only repeat what was said earlier:

I do not own such a modem myself, so I can only try to help basing on my previous experience with the similar modems.
I know that some commands are locked in some fw versions. I suggest to load the generic (non-operator, not branded) firmware. No guarantee it will help though.

And as always - please mention the firmware version used in all [un]success stories.

It works on e3131 . Thank you

The only thing to work I had to modify the file lte.cfg
