I only want to understand the solution you propose to me and not denigrate what you propose to me. ...

Sorry for overreacting.
Be honesty to you is not easy fix device remotely.

In another device, this sim card works. Happened after the firmware with formatting UMI S2 device. I believe that you need an image of nvram.img, do you happen to have it?
