I am trying to upgrade to RG520NNADAAR03A03M4G_ failed

Hello @US_michael
What kind of Firmware tool version and operating system version are you using?
The latest firmware tool that I know is QFlash v6.5, and Quectel literature recommends the use of Windows 10 64 bits…

If you need the Qflash tool, I can send it to you.


I use Qfirehose to upgrade,thank you for help!

@US_michael Ok, is nice to try to help, indeed.
Have a great day :wink:

Check the release notes for your firmware for required QFirehose version.

Dear @US_michael
RG520NNADBR03A01M8G and RG520NNADAAR03A03M4G_ are different, they are two projects, RG520N-NADB and RG520N-NADA.
RG520NNADBR03A01M8G_01.001.01.001 is the latest firmware for RG520N-NADB, please check your current firmware via AT+QGMR.

RG520NNADBR03A01M8G cannot be upgraded to RG520NNADAAR03A03M4G_

Can you send me the firmware RG520NNADBR03A01M8G? thanks!

Dear @US_michael
They are different project, so you can’t upgrade.
I have sent the RG520NNADBR03A01M8G to you via Message, please check.
