just another lg g7 bricked

Hi,

I have a lg g7 (lmg710n) bricked that I am trying to fix.

It shows nothing on the screen, I only was able to enter 9008 mode by shorting the two tests points and plug it in my win 10 PC.

I followed the steps presented in the first post and got to step 17 - download. I am stuck here with Download Fail:Sahara Fail:QSaharaServer Fail: Process Fail

Can anyone help pass this step?

Update 1

- QSaharaServer works in the first few 1-3 seconds after entering the 9008 mode.

- I deactivated driver signature enforcement in Windows 10 (google it) and put Windows in test mode

- FireHose Fail issues fix: use QFIL (run as administrator)

from QPST

...but now I have another issue:

{ERROR: ReadPort:5333 Could not read from '\\.\COM4', Windows API ReadFile failed! Your device is probably *not* on this port

Update 2

- still at the same error.. most probably I need to find a proper Qualcomm driver
