Updating procedure huawei e220

The Huawei E220 is a Huawei HSDPA access device (modem) manufactured by Huawei and notable for using the USB interface (USB modem).

Technically it is a modem, USB and (due to the CDfs format) virtual CD-ROM device.

The dashboard is the program that you use to connect to the network.

This is the same dashboard that your provider tweaked to add subscriber-only restrictions and functions. The dashboard is said to work with any provider AS LONG AS you have the correct information like APN, Number, etc of your network provider.

Updating the modem's Dashboard does not remove or affect the network-lock (that may be in effect with modems purchased subsidized from a service provider) that prevents you from using the modem with any service provider.

However updating the modem's firmware may remove this network-unlock or even the opposite, turn a network-unlock free modem into an unlocked one.

As mentioned above, after the firmware update, the modem stopped detecting 2G networks.
