I was restless as I needed to go online at that moment but there was no device that I could use to get my PC connected to the internet, during my confused state, I realized I have got an MTN modem that I had hardly use. While other network sim was inserted, I plugged and played the modem on my PC via its USB port only for me to discovered that the 10 attempts for unlocking most zte and huawei modems have been used up.
While still thinking of what to do, I hit Google and visited some webpages on all sorts of datacards unlocking issues and problems relating to mine, I was able to do the following to have my modem unlocked, flashed, re-unlocked, upgraded and re-installed. These are the three steps I followed and yours should be similar:
1. Re-calculate the modem unlock code
2. Flash the modem
3. Download and Upgrade the modem model firmware
4. Download and install a customized dashboard
#1. Re-calculate the Modem Unlock code
You can calculate your modem unlock code manually or automatically. You can download this software if you want to generate your modem unlock code manually, download this Manual Modem Unlocker or this Automatic Modem Unlocker that will initialize and read your modem up from its COM Port. Please know that you will need this unlock when you’re resetting and flashing your modem.
#2. Reset the Modem
Download, extract and run this software for restting and unlocking huawei modems

Underneath “SERVICE” on the left side, tick “RESET MODEM” thereafter, you should click “READ MDM DATA” you will then need to wait for few secconds and finally click “Unlock”

#3. Download and Upgrade and the modem model Firmware by Flashing
Even after following the above steps, your modem will be showing 10 of 10 used, invalid sim or network selected or something similar to this statement.
You’re going to need to down the specific firmware update for your modem or datacard model. This you can easily get and download free from DC Files
When you get to the webpage, select your modem make (huawei) from the drop down menu and click the icon. The next and third page will be where you will be able to select the model of your datacard and the most recent firmware update respectively
After a successful download of the file which is about 7.41MB, this software size varies, depending on your modem make and model, unzip and install
This your modem firmware update wizard will search for your device for some seconds, and its shows another page displaying the configuration and IMEI number of the modem
The next steps flash your modem and you will see a message “The wizard is ready to update your Data Card” on your comuter screen from the page environment displaying four warnings
Click start to authorize this process and you will be prompted to enter the modem unlock code you got from step 1
After like 3-5 minutes, your modem should have been flashed and a new copy of the firmware installed
Once the process completes, you will see a successful update message as you can see from the image below

You might also be asked to enter an unlocking code again, at this time your modem counter had been reset to zero (0) of ten (10). You re-use the manual or automatic approach in step one above.

Benefits/Importance/Advantages of Flashing and Installing a Different Firmware and Dashboard Updates
As you could see from the image above in my newly fixed huawei E156G data, in front of the 3G 62120 there is the word “turbo”, this is not just having literary meaning, it simply means speed at which the modem alongside with its firmware and dashboard are working. Before I did this, MTN and AIRTEL was so poor in my location, but after this, they are now rocking with amazing speed

I was equally experiencing fluctuating server downtime, but after this fixing, update and upgrade, it has been minimized
