Well here, I think, there are two options.
Option 1 - dump ration modem. A temporary "treatment" is known (safety is not guaranteed! At your own peril and risk!) - put the phone in the freezer for a while. Then get it and immediately immediately flash it (some right there they plug in the cable from the laptop and sew). The principle of operation is very simple - the contact geometry changes with the temperature, the “broken” connections converge again.
Normal repair - in the workshop to do the repair.
Here, of course, the question arises - why did it work fine before the firmware? As far as I know, the fact is that a number of contact “legs” of a modem are used only for the purposes of firmware, and not during normal operation. If these "legs" have defects / dumps, then ... We get what we got.
Option 2 - the modem is out of order. It is possible (but I haven’t heard about it) that my not entirely correct actions (pressing "Update" instead of "Restore" on the phone with Jb might have been pulling out the cable during the firmware, etc.) or just some randomness The modem's software system's “area” turned out to be where the IMEI, firmware, etc. are stored. But I have not heard about such cases of error -1 ...
