where can i get 6.52 firmware to reflash my q2406b?

I need firmware 6.52 to reflash my q2406b module. Currently it’s like half dead, couse it doesn’t respond any command. It only keeps sending WIND and CGEV response.
I have ask my distributor but they can provide it. Infact they don’t understand what I ask for, they only know to sell, but they have no after sale service. I also have search all this forum and doing ‘google’ but I can not found ones.
Anyone have those firmware please be kind to share with my, at least let know what is the link to download.
Or maybe there is another solution to fix the problem.
Thank you.

Any luck if you get the whole SDK package and use the firmware inside?

Good luck


If things are so bad, the only solution is reflashing with DwlWin. For Q24 you need firmware in form of special E2P files, where SDK is not a valid source. Your distributor can ask SW about package needed for Q24 reflashing by DwlWin.
I think, i have such package somewhere, cant remember firmware version…
