Teltonika FM1204

Dear Friends

We have problem with upload_cfg command for Teltonika FM1204.
We can do it well for Teltonika FM1100, but it is not working for FM1204.
We prepared profile and command for FM1204.
We sent command to device, and nothing happened.
In FM1204 console there was no information about received SMS, about profile update.
We done the same things for FM1100, and we had info about sms in console, profile was updated.

Has anybody had such problem with FM1200, FM1202 or FM1204.
From my knowledge all Teltonika dvices have the same protocol, so it should work.
