Browse Source 
With some debug in qmi.sh using following patch, some errors are visible
in the registration step

During the boot of the system, modem could not start automatically its
network registration.

As the while loop checks only "searching" pattern, uqmi.sh script quits
searching loop and continues whereas the modem is not registered

Other issue, after X seconds modem stops searching.

If registration_timeout is not expired, registration can be restarted
