Hi, I made a mistake to update Wavecom Wismo Q2406B board with firmware 657e\_full\_Q2406, but with no luck … I receive some errors: 00:00:00 FLASH Management : Load flash values 00:00:00 Error\_Handler Wavecom : 0x10 16 - AD I try to downgrade to 657b but I don’t find the firmware… The bad thing it’s that I didn’t made a backup … Can someone help me with a working firmware for this model? Thanks! Stefan ---

This seems to be old module… Better you contact your distributor to resolve this issue… But one point, as per my understanding it support 6.57e. -Alex ---

Are you sure the application build in the same firmware version as that of the module? -Alex ---

No, I’m confused … I don’t understand where I’m wrong … I know that I have Wavecom Wismo Q2406B board, because it’s written on it … It’s there any solution to find right firmware and application for it? Thanks! Stefan ---

I don’t know much about Q2406B, but for other SWI product we use ATI9 command to know more about application and firmware. -Alex
