BG96 failed firmware update

Hello,

It seems like some of my BG96 modems are bricked after a failed firmware update using QFlash. The 4 COM ports (DM etc) don’t pop-up anymore, and we only see ‘Quectel QDLoader 9008 (COM18)’ in the device manager (is this force download mode?).

I’m using QFlash 7.3 and the firmware update package is ‘BG96MAR02A07M1G_01.202.01.202’. QFlash is busy for 95 seconds and then shows ‘FAIL, DL_Firehose, Time out!’. Baudrate 460800, using the QDLoader 9008 port.

The state of the USB_BOOT doesn’t seem to change the state/mode of the BG96 modem.

How can we flash the firmware in these devices?

Thank you.

Could you please show me the screenshot of your device manager?

This is my device manager:
s1

Could you please tell me the FW version before updating?

The firmware version before updating was ‘BG96MAR02A08M1G_01.012.01.012’.

@mikey Any updates on this topic? Do I have to flash the previous firmware into the modem? I don’t have the firmware update packages files for this version.

Sorry for the late reply, this model is not support rollback function so update R02A08 to R02A07 is not supported.
