Do I need credits do I need to downgrade my device's firmware?

[Valdemaras]

Do i really need to repeat everything? We will continue this conversation only after you provide your username that you receive after credit purchase, because as i see you are doing nothing just asking questions in circles.

I've tried it, the response is "service is not available for client".

You are getting this message because you are not carefully reading what i'm writing, "Provide us your username too, since without us knowing it, program won't start."

Thanks.
When I tried to unlock my MODEM some days ago, I generated a firmware code by IMEI and credits were deducted, Is this firmware code useful at all?

If you want to upgrade firmware from original updater and it asks for firmware upgrade code, then useful.

What do I do?

[Valdemaras]

You repeat the process is what you do.

[Oluwatobi Oloye]

When repeating the service, do I put an invalid SIM or valid SIM in the MODEM?

You put no sim because it's irrelevant for flashing.
