1. Pay attention to checking the device manager. During the upgrade process, you will be prompted to insert a new device, and there will be no device driver for the first upgrade;
2. Pay attention to the USB cable. During the upgrade process, the speed of the USB cable is relatively high. You need to choose a better-quality USB cable to avoid poor contact.
3. You need to run the upgrade tool with administrator privileges (sim7000 qdl v1.43 only for update)
4. Uninstall and reinstall the upgrade tool (sim7000 qdl v1.43 only for update)
