As described to Oliver before, I try to catch a MiTM, and my Android is
near-brick statement..

In my case I observe different behavior of Android phone. When
connected in fastboot mode I can see adb devices output:
0123456789ABCDEF        offline
this fake serial number belong Ragentek j5808 chip.

And I have made symlink /dev/mediatek in udev rules, it's looks like
work, I cal see it wit ls -la (but can't send|receive AT commands via
minicom). 

If I boot normally, the output  of adb devices shown as
X560I1ZR5A241388        offline
this serial belong to real Mediatek Android device.
