I would like to try reinstalling the firmware. I also need the USB drivers since I have a new laptop. Some instructions will help. I did the update 3 or 4 years ago, and I am rusty.
I can share with you my drivers and tools EP06-ela + all tools and drivers it includes all drivers, documents and tools for Quectel modems, and firmwares for my modem, till this month (Dec 2025). I hope that it can help you.
Have a great day
