RM500Q-GL Firmware update failure

Hello Quectel Support,

I recently flashed my RM500Q-GL with the new firmware version RM500QGLABR01A01M4G_01.001.01.001 via QFLASH. Upon powering the card back on I only detect a QDL port. I am able to get an at port for about 3-5 seconds after powerup. I ran the ATI command and confirmed the new firmware image but it just powers down quickly and I am unable to see the device again. I used USB drivers v2.1 on a WIndows 10 machine. How would I solve this issue?


You can try the latest USB driver v2.2.2 see if issue can be recovered.
Just for reference, powersupply insufficient would caue this issue.

Hello there,

I have this same issue with the same related product, but after updating the usb drivers you linked the problem still persists.

Do you have any other solution?

Thanks in advance,
Kind Regards
