Sorry due the hardware limits of the X2000, there is no good way to do full update.
There is the differential update package EG120KEAAAR01A11M2G_01.200.01.200 available for X2000 EU version. You can choose to update to this version.
there is no good way, or is it not possible at all?
Sorry for asking again, it's just really important to me.
It's hardware limitation, and it's not possible to update the modem using the full upgrade package
Sorry but we would suggest to contact quectel for further assistance.
