We are using Quectel 5GM2EVB and an RM520N-GL module.
QFlash finished the flashing process but after the reboot, we no longer see the device in the Device Manager.
Is there an emergency download mode that could be used to reflash?
Thank you.
Dear @Marcin_Jaszczuk
Could you share the original firmware and target firmware? Did you try to power on and retry? Could you share some screenshoot? like the device manager, your module and EVB.
Hi Silvia,
Thank you for getting back to me. We actually found a solution, w followed the steps outlined in
I bricked RM500Q-GL with ATS command so Windows 10 no longer sees USB; is there a way to flash firmware? - #4 by Peter.Zhu-Q for a similar module and it worked.
I forgot to update this thread.
Support is no longer required, thank you.

Please help regarding this issue
Dear @ankit1
Please share the screenshoot, thanks.
Dear @ankit1
Please upgrade the firmware, is there any problem on your device? Or is it a engineer sample?
I tried but it fails always i locked my bootloader with a cutom signed fw . So now mynew fw with same specs but not signed by that sign is not flashing
Dear @ankit1
What do you mean of custom signed fw?
Is it enable secure boot?
(post deleted by author)
Yes secure boot is enabled . Due to secure boot firehose is not working and also sahara mode fails .
Dear @ankit1
If enable secure boot, please contact with your supplier to get the firmware.
My supplier is not providing firmware . Does any way to flash custom quectel firmware of this model by erasing whole data of module
Dear @ankit1
Sorry, we don’t have this.
