How I fixed my "QD loader issue"

Post by daniel.bedard » Sun Jun 16, 2019 7:20 pm

To solve my QDloader issue on windows that appeared after some mods I tried...

I updated driver on the QDloader device with the driver for "USB composite device" driver.

Then the different devices from the modem appeared!

I then updated the driver on the modem port with "MI_03" in the hardware ID with the "Huawei WWan Broadband Modem" drivers I previously downloaded.

This allowed me to return the modem to factory by doing:


Then my modem was back at Factory so I could resume or retry to re-brand / change the identity of my modem.

This worked on my EM7455 that I was trying to re-brand while I introduced errors that caused the QDloader problem.
