ALTERNATIVE TO DC-UNLOCKER , if you guys don't want to use above mentioned dc-unlocker for any particular reason & privacy issues then totally its your choice , you can ignore the above method of typing the command in dc-unlocker but instead You can use "PUTTY" already included in huawei files attached here ..

just do some configuration before you use putty any further, open putty choose connection type as "serial" and select com port number , in my case its 7 as you can see in below pics,

under terminal sub category choose "force on" for both local echo and local line editing then go back session category and click open then a terminal window will open . this is where you communicate with your modem device and listen to them by sending commands , you just type the same command as said before . this command >> AT^NVRDEX=50503,0,128 and copy the whole data from terminal and paste it in here at this forum and then go to upgradation process of firmwares.
see pics for more explanation .

For UNlocking ... after you get the unlock code and changing the sim of other operators , you can go to your device portal 192.168.x.x and put the code right away or you can download "Huawei HiLink" android app from playstore and open it >> setting icon at right top >> device >> unlock
or you can also unlock it by using at command >>AT^CARDLOCK="apka 8 digit vala unlock code" ..thats it

No worries at all if you see such type of error like the picture shown here below , or anything related to not detecting modem, or this firmware upgradation is hectic process? No. not all, its not like android firmware and OS upgrade that is complex and limitation with kernel and downgrades but no complexity with zong modem devices so far, zong modem firmware changes is just a few clicks of your mouse game and its simple .... if you need drivers or huawei tools in case if you don't want to use dc unlocker and you want to use "putty" for sending commands & establish communication with modem or use "huawei terminal" , any alternative you can use, just download all from here https://www.dropbox.com/s/r8i450xoov...0files.7z?dl=0 but these tools that is probably you will not need further if you follow my guidelines properly. Just few items you will need in huawei files that i mentioned earlier .

>> in case if you needed this step which you use when you connect your device to your pc is to switch it to Debug Mode. this will give you access to additional available COM ports which you say it serial COm ports which later we use to unlock the modem, you can switch your device to debug mode easily by clicking on sw_debug_mode.exe which is included in this link.. https://www.dropbox.com/s/69y3hoxxdt...20mode.7z?dl=0
