Newtec MDM2200 satellite modem firmware?

Question

network hardware

Hello. The following situation happened: 4 years ago I bought a kit of Kitenet equipment, but in the end the need for it disappeared and for 4 years this kit was actively covered with dust, but enthusiasm tends to appear unexpectedly, so not so long ago I decided to use the services of the Lansat satellite Internet provider. After talking with technical support, we decided that the transition with this equipment is possible, after which I zealously set about setting up a satellite station. It was not possible to use the standard tweeter, because for 4 years it was safely lost, so I had to resort to using the ku band satfinder. Satellite Yamal 401 at orbital position 90* East. So here's the gist: Brought the signal to a level of 13.7dB, when trying to initialize the modem at the stage of uploading the firmware (it costs 2.2.6.14, loads 2.2.6. 15) after 30-35 percent, the process resets to zero and repeats cyclically. I did not find instructions on the Internet, so I decided to ask here, because I have already broken my whole head. If the problem is with the transmitter, is there anywhere to find materials for self-repair, because, alas, there are no service centers in this direction in my locality.
Are there any ways to upload firmware to this (MDM 2200) modem in addition to uploading from a satellite?
Thanks in advance.
UPD: I turned on installation cerrier mode, the firmware from the satellite was uploaded, but the initialization does not work anyway, writes Network login failed
