After flashing f/w you have to restart the module. Open Main COM port in putty and send AT commands it will gives you the response.
You have to send AT commands.
i try to enter AT on putty but it will not respond anything and blank display as it is,also i change baudrate like,9600,115200,19200 but not get any respond on putty.
and when i was upgrade firmware after select FW file ,module type is not displaying on latest Qflash software.
Hi People, I have a problem with fw update on the M66 modem. The tool QFLASH works totally fine when we have evaluation board with power buttons. Could you please let me know how update of fw is possible when modem is fitted on small PCBs.

When I tried uploading GPIO example firmware, It starts and then I get this error.
my M66 firmware version is M66FBR03A07
I read other posts and as advised by @rahul.mahakalkar , I downloaded Qflash4.19 and then downloading worked. Initally I was using QFlash that came with SDK downloaded from quectel site.
