[G4 Q&A, Help & Troubleshooting] liyafe1997:
MY G4 had been hard bricked servial weeks. I am finding some ways to unbrick it via usb.

Now I found some mbn files (use in QFIL) for MSM8992, form Lenovo X3c50/X3c70 and Xiaomi MI4C.

But those seems not working for G4 in QFIL.

Here is the log in QFIL:
