Hi @leon.bao, do we need to boot the module into EDL for allowing the Firehose flashing tools (QFIL)? When so, is there a utility that facilitates a software-triggered transition to EDL via DM port (win11)? Or better, is there a preloader or signed firehose assistant tool for the Firmware?
Hi,@mister.bagger
Usually, QFirehose doesn’t require the module to enter the EDL mode. You just need to select the correct directory name of the firmware package.
Hi @leon.bao,
Is firmware RM520NGLAAR03A03M4G_A0.301.A0.301 the latest version?
Is there no newer version?
When so, can you send me the link please?
Thank you,
What you own now is latest. Much appreciation.
