Īctually i would rather not being a kid here and likely to share the source code of it. I am here not to explain more about how to or ' how not to' Use this but i was actually here to share my internal work too. In the end You all use the calculator which i have attached here. a command windows will open and you will type the same same command. In Putty ,On your left categories you choose Terminal and choose 'force on' for both Local echo and local line editing.and back to Session window and choose Serial and the required COM port of PC UI application. Using Dc unlocker its automatically detect the available COM port and simply you put this command AT^NVRDEX=50503,0,128 in the end and enter. So Thats why i simply prefer to use 'Putty' or you can also use DC-Unlocker While Using Huawei Code Reader you will get hash1 and hash2, its actually the same pattern if you copy that in a notepad and put a single space between and after each 2 character, it will be like 32 pairs of hexadecimal values ( in programming language you can say that a string of 95 characters) You will get the same patterns from all of the above mentioned tools.

Its the same if you use 'Huawei Code reader' or 'Dc-Unlocker' or 'Putty' or 'Huawei terminal'.

You just type this and get the required pattern and thats it. So the whole scenario goes around a single command that is 'AT^NVRDEX=50503,0,128' WITHOUT quotes in the below mentioned tools. and this has been tested on the following devices successfully as i heard from more and more people now a days. So you guys say it so called v4 unlocking codes. so i am about to proceed with no more extra or comprehensive details of how you extract NV data but i am attaching screenshots. You Guys familiar with Unlocking codes in to your 3g/4g modem devices.
