EM12-G QDLoader

Hello there
I have EM12-G that after start shows only 1 device: Qualcomm HS-USB QDLoader 9008
With VID/PID: USB\VID_05C6&PID_9008&REV_0000
I have tried to flash it with QFlash v4.18, but no luck, i get error:

How to flash FW to this module, any advice? Thanks for answer!


  1. Please first confirm that the EM12-G model information in your hand and the target version information you want to upgrade belong to the same type of EM12-G model. If the EM12-G model is different, the upgrade will fail.

  2. Use the qflash tool to select the USB DM port and select 115200 baud rate for upgrade.

I hope it was helpful. Thank you.

hello there, I’m having the same issue with simcom sim 7600g r2 when i try to flash to it will come up with failed to connect to Sahara server or failed to open serial port.


Any ideas?

Thanks for answer!
